Abstract

For

the last sixty years, African-Americans

have

been

75%

more

likely todie during infancy as whites.

From

the

mid-1960s

to the early 1970s, however, thisracial

gap narrowed

substantially.

We

argue that

the ehmination of widespreadracialsegregation in Southern hospitals duringthisperiodplayed a causal

role in this

improvement.

Our

analysis indicates that Title

VI

of the 1964 Civil Rights Act,

which

mandated

desegregation in institutions receiving federal funds, enabled 5,000 to 7,000 additional black

infants to survive infancy

from 1965-1975 and

atleast25,000 infants

from

1965-2002.

We

estimatethat

by

themselves theseinfantmortahtybenefitsgenerateda welfare gain of

more

than$7 billion(2005$) for

1965-1975 and

more

than

$27

billion for 1965-2002.

These

findings indicate that the benefits ofthe

1960s Civil Rights legislation extended

beyond

the labor

marker and were

substantially larger than

recognizedpreviously.

Over

thenextten years, theinfant mortalityrate

among

U.S. blacks fellto

24

perthousand.

Among

black infants

bom

in1975, roughly 7,000

more

babiessurvivedtoage 1 thanif

the pre-1

965

trend

had

continued. Further, the gap

between

black

and

white infantmortalityrates

(IMR)

narrowed

substantially duringthelate 1960s

and

early 1970s (Figure la). Indeed, these years comprise

the soleperiodoflargereductionsintheblack-whiteinfantmortalitygapsince

World

War

II.'

In this paper

we

establish that

much

of the 1965-75

improvement

in black infant health

was

driven

by

a sharp decline in post-neonatal mortality rates

(PNMR)

in the rural South.^ Figure lb, for

example,

shows

the

number

ofpost-neonatal deaths

among

black

and

white infants due to diarrhea and

pneumonia

inthe stateofMississippi. In the early 1960s, post-neonatal death ratesfor these

two

causes

were

6-7 times higher

among

blacks than whites

and

showed

no

trend toward relative improvement.

Starting in 1966, however, the

number

ofdeaths

due

to these causes

plummeted

among

black infants,

while the

number

for whites

remained

nearly constant. This dramatic trend breakin fatalities forthese

two

causes is important because they contributed to a high fraction ofoverall black infant mortahty

and

effectivetreatmentsforbothconditions

were

well

known

and

widelyused.

We

arguethatthetrendbreakinblack

IMRs

in the

mral

South

was

driven

by

federally

mandated

desegregationefforts thatincreasedaccess tohospital care forblackinfants.

Of

theevents thatledtothe

mandated

desegregation,

two

stand out as central.

The

passage ofTitle

VI

ofthe CivilRights

Act

inJuly

1964

prohibited discrimination

and

segregation in any institution receiving federal funds. Second,

hospital eligibilityfor

payments

underthe

new

Medicare

program

-

begun

July 1,

1966

-

was

conditioned

on

eliminationofthe racially discriminatory practicesthat

were

common

atthe time. Together,the Civil

Rights

Act and

the financial leverage exercised

by

the

Johnson

administration led to the opening of

previously "white-only"hospitalstoblacks

and

theend ofexplicit racial segregationinhealthcare.

'

The

National CenterforHealth Statisticsswitchedfromcoding racebased onthe infant's race to therace ofthe

motherin 1990. Consequently, itisimpossibletoextendtheseseriesbeyond 1990inaconsistentmanner.

"Conventionally, infant mortalityis definedas the deathrateofinfantswithintheirfirstyear oflife. Post-neonatal

mortalityisthedeathrate intheperiodfrom 28daysto 1 yearafter birth. Neonataldeaths are thosethatoccurinthe first28daysafter birth.

(12)

We

implement

a battery oftests to evaluate thehypothesis thathospital desegregationcausedthe

large reductions intheblack-white

IMR

gap.

The

results ofthese tests are strongly supportive. First,the

reduction in the black-white

IMR

gap

began

immediately after integration

and

was

largest in the rural

South

where

blacks' access to hospitals

was

the

most

constrained. Second, within the rural South, the

decline

was

concentrated

among

post-neonatal deaths,

which were

more

preventable than neonatal

fatalities at the time.

Roughly

two-thirds ofthe decline in relative

PNMRs

was due

to a reduction in

pneumonia

andgastroenteritisdeaths,

two

causespreventable

by

hospitaltreatment.

The

most

demanding

test

comes from

a case study of Mississippi. Despite strong financial

incentivesprovided

by

Medicare,

many

hospitalsin Mississippi

were slow

to integrate.

We

evaluate the

impact ofthose delaysusingan event-study approachthat is based

on

detailed,hospital-leveldata

on

the

timing ofhospital compliance with Title VI.

We

find

immediate

and

large reductions in post-neonatal

mortality, especially

among

conditions

most

treatable in hospitals,

when

a hospital in the county of

residence

was

certified as desegregated.

These

gains

were

not shared

by

white infants,

and

they are

robusttoadjustmentforvarious alternativehealth determinants,such asmaternalcharacteristics(e.g.,age

and

marital status), transfer

payments

(including

Food

Stamps),

Medicaid

participation,

and

per-capita

income. Further, the

same

approach findsan

immediate

and

sharp increase inthe fraction of blackbirths

inhospitals,

which

corroborates thevalidity ofthe federal governments' claims ofsuccessful integration.

Thus,the evidence appears inconsistent withalternative explanations, including an innovationinmedical technologyor a

change

blackinfants'

home

environments.

Overall, our analysis indicates that this federally

mandated

desegregation of hospitals enabled

over 5,000 black infants to survive until age 1

between

1965

and

1975 in the rural South

and

25,000 through 2002.

We

estimate thatthe infant mortality benefits alone

were

equivalent to a welfare gainof

$7.2 to $11.1 billion (2005$) for blacks

bom

in the rural South

from

1965-1975.

For

the

1965-2002

period,

we

estimate gains

between

$27.5

and

$41.9 billion.

These

findings indicate that the benefits of

the 1960s Civil Rights legislation extended

beyond

the labor

market outcomes

considered previously

(RobertNash,DirectorofOfficeof Equal Health Opportunity, 1966)

The

South

was

a deeply segregated society throughout the 1950s and early 1960s. This

separation ofracesextended to all areas oflife, including the provision ofhealth services.

A

Journal

of

theNational

Medical

Association survey of 523 hospitals administeredin

1955-1956

foundthatwhile 87 percent ofhospitals inthe

North

had

a "policy ofintegration", only 1 percent ofhospitals in the South

had

one. Further,a 1956 survey of

2400

Southernhospitaladministrators foundthatonly 17 percent

were

wiUing

to accept desegregation, with 62 percent adamantly opposed, 10 percent favoring separate

hospitals,

and

11 percent unwilling to respond

(Seham

1964).

These

policies continued into the early

1960s.

A

1963 survey found that 85 percent of southern hospitals reported

"some

type of racial

segregation or exclusion,"

compared

to less than 2 percent in northern

and

western states (U.S.

Commission

on

Civil Rights 1963:141).

The

pattern ofdiscrimination usually "consisted ofa separate

wing

or floor for

Negro

patients"insingle-building hospitals (U.S.

Commission

on

CivilRights 1966:10).

A

relatively unrecognized^ aspect of hospital segregation

and

exclusion in the South

was

the

federal government's role in supporting itboth legally and financially through the Hospital Survey

and

Construction

Act

of1946, also

known

as theHill-BurtonAct.

Two

decades afteritsenactment, 350,000

hospitalbeds (orapproximately halfofthe existing beds inthe

US)

had

been

constructed underthe

Hill-Burton

program.''

As

Hill-Burton funding

was more

generousinpoorerareas

(DHEW

1966), the federal

government

was

the

dominant

force in the postwar hospital construction in the South.

The

1946

^Reynolds

(1997) and Smith(1999,2005) are notable exceptions.

"

Almond

(14)

legislation that enactedHill-Burtonexplicitlyinvokedthe principleof"separatebut equal" with regardto race. Thisclause

remained

despite thefact that otherparts ofthe legislation

were

amended

and

extended

several times both before

and

after the 1954

Brown

vs.

Board

of Education

decision that "separate but

equal"

was

unconstitutional.^'^

Moreover,

the Hill-Burton

program

funded health care facilities that

specifically excluded individuals

on

the basis of race.'

The

Hill-Burton

Act

was

the only federal

legislation to codify racial segregation

and

exclusion since the 19th century (Smith 1999).

As

Seham

noted in the

New

England

Journal

of Medicine

in 1964,

"To

20,000,000 citizens, discrimination

and

segregationfollowed"

from

theseparate -but-equal clauseoftheHill-BurtonAct.

were

While

black hospitalization

rates forlabor

and

and "Elsewhere"

(largelythe

Midwest

and

West),largegapsexisted intheSouth.

For

residentsoftheRuralSouth,

40%

of

black babies

were

not bora in a hospital with a doctor present, while the

comparable

figure for

whites

was

only

4%.

The

racial disparity

was

still larger in Mississippi;

more

than halfof black infants

'

After the

Brown

decision, Hill-Burton program administrators repeatedly requested that the program cease

followingthe"separate but equal"doctrine. For example, aFebruary 1963

memo

fromtheGeneral Counsel atthe

DepartmentofHealth, Education, and Welfareto theAssistant Surgeon General states, "Theacceptanceofinternal

segregation atinstitutionswhichadmit bothraces isalso,Ibelieve,inaccordwiththeintent of Congressatthetime

when

thelegislationwas enacted,and in this respect alsoCongresshas

made

nochangetothelaw"

(DHEW

memo

February 12, 1963:1). This

memo

goesonto arguethatHill-Burton"administrative officers"have nochoicebutto

continue to award grants to segregated health care facilities "despite any doubts they individually

may

entertain

regardingthe constitutionalvalidityofthestatutes" (ibid).

^

As

lateas August, 1963, theU.S Senaterejected aproposalthatwould haverequired grantsunderthe Hill-Burton

Acttohospitalsthatdidnot discriminateonthebasisofrace (U.S.Court ofAppeals FourthCircuit1963:23)

that "certain persons in this areawill be denied admission to the proposed facilides as padents because ofrace,

creed, orcolor" and reportedto theSurgeon General thatotherfacilities fortheexcluded racewereavailable (U.S.

Court ofAppeals Fourth Circuit 1963:7).

A

total of89 hospital construction projects in 14 stateswere approved

withthestipulation thatonlyoneracewouldbe admittedtothefacility(U.S.Commission onCivilRights

1963:130-131). Ninetypercentofthefundsforthese discriminatingfacilitieswentto all-whitefacilities.

'

We

define the "Rust Belt" states as Illinois, Michigan,

New

York, Ohio, and Pennsylvania. The South is

comprised of 17 states (including Washington DC), as assigned by the

US

Census Bureau.

We

refer to

non-metropolitan and metropolitan counties as the "rural" and "urban" areas ofa state. With the exception of

New

England, counties are classified as "metropolitan" if they are included in a Census Bureau-defined Standard

Metropolitan Statistical Area (SMSA). Race was coded aswhite and non-white inthe Vital Statistics data in this

period. In 1968, the non-white categorywas subdivided and

we

found thatblacksaccountedfor

99%

ofnonwhite

infant deaths intheUrban Rustbelt,Urban South,Rural South, and Mississippi. Thecomparable figure forUrban

Elsewhere is 93%.

We

exclude Rural Elsewhere from the analysis because blacks only accounted for 52%i of

bom

2%

ofwhites.

Panel

B

uses data

on

the

number

of hospital beds available for white

and

"colored" patients

collected

by

the Mississippi

Commission

on

Hospital Care.'°

The number

of hospital beds per 1,000

births allocated to blacks versus whites in the early 1960s is reported." This

measure

of access to

hospital careis relevantbecause certainlife-savingtreatments for infants

were

onlyavailable athospitals.

More

than twice as

many

hospital beds

were

available to whites as blacks in the predominantly white

counties.

More

than five times as

many

hospital beds

were

available to whites as blacks in the

predominantly blackcountiesofMississippi.'^

Low

hospitalization rates

and

bed

ratios reflected the inferior

medical

care available to

blacks

tmder

segregation.

Senator

Javits

of

New

York

stated to the U.S. Senate:

"Segregated

hospitals

and

segregated

wards have

resulted in

over-crowded

conditions

and

substandard

facilities for

many

Negro

patients,"

who

are often "relegated to

basement and

attic

wards."

Javits further

noted

that:

"Often

when

Negro

wards

are filled,

no

additional

Negro

patients are

admitted

even

though

there

may

be

empty

beds elsewhere

inthehospital." (Javits 1962).

That such data were collected annually reflects the degree to whichracial segregation was institutionalized in

'^ There was even evidence that Southerners' commitment to this system was growing as a reaction to the

burgeoning Civil Rights movement. Caro (2002) argues thatthe early stages ofthe Civil Rights

movement

in the

1950s led to increased violence by whites against blacks and a renewed focus on preserving the system of

(16)

First, in 1963, Dr.

George

Simkins, a black dentist in Greensboro,

North

Carolina, joined with black patients and other physicians in suing

two

hospitals

which

denied blacks admission

and

staff

privileges.

These

hospitals, although private,

had

received federal Hill-Burton construction funds. In

November

1963, the Fourth Circuit Court of Appeals decided Simkins v.

Moses

H.

Cone Memorial

Hospital in favor ofthe plaintiffs.

The

court declared that the section of the Hill-Burton legislation

permitting "separate-but-equal" health facilities

was

unconstitutional.''' Furthermore, the majority

opinionstated: "Racial discriminationin medicalfacilities is atleastpartlyresponsible forthe fact that in

North

Carolinathe rate of

Negro

infantmortality is twicetherate forwhites...." (U.S. Court

of Appeals

FourthCircuit 1963:14)'^

In

March

1964, the

Supreme

Court declinedto review the

Appeals

Court decision, leaving it in

place.

The

immediate

resultofthisdecision

was

that

new

applications forHill-Burton funds

and

pending

projects

were

allrequiredto be nondiscriminatory withrespectto admissions, staffprivileges,

and

access

to all portions ofthe facilities (Smith 1999). Since halfofall Hill-Burton grantees

were

private,

non-profits

(DHEW

February 12, 1963),thisruling's impact

was

notsimplylimitedtopublic healthfacilities.

However,

this ruling did not affect segregated hospitals that

had

previously received Hill-Burton

funding.'^ In fact,

lawmakers

cited the Simkins case as demonstrating the

need

for definitive federal

legislation.

Passage ofTitle

VI

ofthe Civil Rights

Act

in July 1964,

which

prohibited discrimination

and

segregationinanyinstitutionreceiving federal funds,

was

the second

landmark

event.'''

According

to the

bipartisanU.S.

Commission

on

Civil Rights,

"Seldom

has anypieceoflegislation

been

sobroadinscope,

sweeping

across departmental, geographical

and

political lines, as Title

VI

ofthe Civil Rights Act of

1964"

(U.S.

Commission

on

Civil Rights 1966;1).

The

passage of the legislation

by

itself led to a

substantial integration ofhospitals inthe South duringthe remainderof 1964 and 1965.

However,

there

'*

Reynolds, 1997refers toSimkinsas "the

Brown

caseforhospitals."

' This viewwas alsoexpressedbythe medical community. Forexample, see

Seham

(1964) inthe

New

England

JournalofMedicine andNash(1968)intheAmericanJournalofPublicHealth.

'^Accordingto the 1963 survey by the

U.S. Commission onCivil Rights,

60%

of segregated healthfacilities had

receivedHill-Burton funds: Reynolds(1997).

'^

In particular, Title VI stipulated that"Patients must be admittedto facilities without regardto their race, creed,

color, ornational origin.

Once

admitted, patientsmusthave access to allportions ofthefacility andto allservices

without discrimination. They

may

notbe segregated withinanyportionofthefacility,provided a different service,

restricted in their enjoyment ofanyprivilege, or treated differentlybecause oftheirrace,creed, color, ornational

remained

pocketsof

noncompliance

in

some

hospitals andin

some

practices (e.g.,integration

of

patients

withinwards),

even

within hospitalsthatclaimedto

comply

withTitle

VI

(ibid).

The

final event

was

the inception ofthe

Medicare

program

in July 1966. Following directions

from

President Johnson, eligibility for

Medicare

reimbursement required that hospitals

end

racial

discrimination.'^

One

observerhas noted: "...Medicare

payments

to hospitals

promised

to be generous,

and

thereby essential. In essence, hospitals

had

to choose

between

affluence through

compliance and

bankruptcy" (Smith, 2005:320).'' Further, in the

months

leading

up

to July, a "Children's

Crusade"

of

750

federal

employees

under the Office of Equal Health Opportunity

worked

to ensure hospital

compliance

withTitle

VI

throughon-siteinspections(Smith 1999:1 13)."°

By

June30, 1966, 92percentofallhospitalbeds

were

in compliance withTitle

VI

(Ibid: 141). In

July

and

throughthefallof1966, the Officeof Equal Health Opportunity

worked

tosecurecompliancein

the remaining hospitals.^' This "quiet revolution"

meant

that insouthern hospitals:

"Negroes

are being admitted

and

treated as

anyone

else for the first time"

1968:246) Notably, Mississippi hospitals

Two

Jacobowitz 1981). For

pneumonia

and

gastroenteritis infections in particular, death could be prevented with timely medical

treatment,^^ in part a resuh ofgreater availabiUty ofantibiotics following

World

War

II (Shapiro et al,

1968). Antibiotics

were

administeredintravenously, togetherwithfluids,inhospitals.

Prior to

World

War

II,

pneumonia and

gastroenteritis accounted for halfofpost-neonatal deaths

for blacks

and

whites alike.^''

By

1965, these

two

causes accounted for under a third of white

post-neonatal deathswhilestill comprising

45%

of black post-neonatal deaths.

The

postwar surge in hospital

capacity financed

by

the Hill-Burton

Program

succeeded in reducing infant mortality, but these benefits

were

concentrated

among

whites

(Almond

etal.2006b).

By

1965, blacks

were

fourtimesas likely to die

from

gastroenteritis

and pneumonia

in the post-neonatal period as whites. Thus, the primary factor

underlyingthe

widening

black-whiteinfantmortality

gap

after 1

(seeFigure 1a)

was

thedivergencein

black

and

white experiences withthese

two

eminentlytreatable afflictions.

D.Implications

Thispaper's goal is to assess

whether

the federally

mandated

integration ofhealth care facilities

caused at leastpart ofthe

improvement

in black infant mortality rates

documented

inFigure 1a. In the

absence ofa

randomized

experiment,

we

proceed

by

presenting aseries ofincreasingly

demanding

tests.

Specifically ifthere is a causal relationship, then the

above

historical context suggests that the datawill

failto rejectthe following hypotheses aboutthedeclineintheblack

1

.

Itshouldexceed the declineinthewhite

2. It should disproportionately occur in the areas of the country

where

3 .

Itshould disproportionately occur

among

causes of death that are

more

4.

Among

the causes of death that are preventable with hospital access, it should respond

regard to gastroenteritis,

Emery

(1976:204) writes that the mortality rate relates to "the eariiness [or]

A.

Data

Surprisingly

few

studies exist of long-run trends in therelative health of black infants overtime.

In addition, the existing research is based

on

highly aggregated data, both across regions

and

overtime,

which

provide little information

on

theprecise location

and

timing ofinfant mortality changes

by

race.

Consequently, evidence on the specificfactorsunderlyingsignificantchangesinblack-whiteinfant health

outcomes

issparse

and

often anecdotal.

To

document

the location

and

timing of improvements,

we

entered data

from

the

1955-1975

publicationsoftheVitalStatisticsoftheUnited States.

Drawn

from

standardcertificates oflive birth

and

death, theycoverthe universeofbirths

and

deathsintheUnited States in eachyear.

We

entered annual,

race-specific (white

and

non-white) seriesfor ruraland urban areas of eachstate.

Our

focus is

on

infant

mortality rates, the ratio ofinfant deaths within a year ofbirth to thetotal

number

oflive births in that

year (expressed as deaths per 1,000 live births),

and

we

also distinguish

between

deaths in the neonatal

and

post-neonatal periods.

As

discussed in the previous section,

we

focus

on

the Rural South,

Urban

South,

Urban

Rustbelt,

Urban

Elsewhere,

and

Mississippi.'^

We

also obtained individual-level electronic mortality data for the years 1960-1975."^

Unfortunately, analogousnatality micro-dataare available only beginningin 1968. Nevertheless,

we

can

use the 1960-75 mortalitymicrodatatogetherwith natalitydataaggregated

by

urban

and

ruralregions of

each state. This enables us to analyze trends in mortality rates

due

to

pneumonia and

gastroenteritis.

These

causes accountedfor

39%

ofallpostneonatalfatalitiesinthe 1960-65period.

B. Trends inBlack-WhiteInfantMortalityRatesby Region,

1955-1975

Figure 2 plots the difference in black and white infant mortahty rates

by

1955-1975. Clearly, large gaps ininfant mortality rates existed throughoutthecountry. In thefirsthalf

of

the period, the difference

between

black

and

whiteinfantmortahty ratesdisplays

no

obviouspattern

-remaining roughly constant in

some

regions

and

actually expandingin others.

Between

1965

and

1975,

however, the racial gap

narrowed

in all regions.

The

timing ofthis convergence is consistent with our hypothesis that federally

mandated

integration ofhealth care facilities

begun

in the

mid-1960s

caused an

improvement

inblackinfant mortalityrates.

Examination

of the regional pattems in mortality gaps provides a

more

demanding

test.

Specifically,

we

expect that the decline should be greater in regions

where

segregation

and

restricted

access

were

pervasive. Again,these mortalityseries supportthisprediction. For

example

among

thefour

regions, the largest decline

from

1965-1975 occurred in the Rural South,

where

the pre-existing

disparities in access

were

the greatest (recall Table 1). In this region, the racial gap declined

by

11.4

deathsper 1,000births, closing fullyhalfoftheinitial disparity.

To

putthis

number

in context, it

means

that4,700

more

blackinfants

bom

in 1975 survived toage 1 than ifthe 1965 black-white differencestill

heldin 1975.^^ InMississippi,

where

pre-1965 access differences

were

especially glaring,the decline

was

16.4deaths per 1,000births."*

Finally, trends in the racial

gap

outside the South track each other well throughout the entire

period.

These

regions also experienced anarrowing oftheracial

gap

inthe 1965-75 period,albeit

35%-40%

smaller than the decline in the Rural South.

The

next

subsections furtherprobethe validity of

our hypothesis

by

and

decomposing

the mortality

intocategories

C. Trends inBlack- WhiteInfant MortalityRates by

Ifthe equalization ofhospital access

between

blacks

and

whites indeed caused the black-white

infantmortality gaptofall,

we

would

expectthisreductiontobe concentratedinthe post-neonatal period.

To

evaluatethispossibility,

which

The

numbers

regressions,

and

the weight is the

number

of black births in the black-white regressions.

The

standard

Table 2 presents the trend breakregression results forpost-neonataland neonatal mortalityrates

inthe

two

setsof columns. Within eachsetof columns, resultsforblack

and

whitemortalityrates

and

the

black-whitedifference are

shown,

although

we

focusour descriptionhere onthe difference regressionsin

columns

(Ic)

and

(2c) dueto space constraints.

The

panels ofthe tablecorrespond tothe fourregions in

Figure2andMississippi.

The

rural Southstands outfor several reasons. First, the pre-1

965

black post-neonatal mortality

rate

exceeded

the white rate

by

15.2 deaths per 1,000 live births. This racial difference

exceeded

the

average blackpost-neonatal mortality rate in each regionoutside the South. Second,the estimates

show

thatthe

gap between

black and whitepost-neonatal mortality rates

was

increasing

from

1955 to 1965 at

the rate of0.18 deaths (per 1,000 live births) per year. Thus, conditions for blacks

were

apparently

deterioratingrelative towhites.

Third, there

was

a largetrendbreakof about 1.4deathsper yearafter 1965. Thisimpliesthatthe

black-whitemortality

gap

intherural South decreased 14deathsper 1,000 births

more

through 1975 than

ifthe pre-1965 trend

had

prevailed. This

improvement

is

comparable

to the pre-existing racial gap.

Moreover,

itimplies that 5,900 additional infants survivedtoyear 1 through 1975 than

would

have

been

expected

from

pre-1965 trends.

The

racialgapinpost-neonatal mortalityratesalso

narrowed

intheother three regions.

However,

theblack-white trendbreak in therural South is 2.5 times largerthan in the

Urban

South, 5 times larger

than in the

Urban

Rustbelt,

and

9 times larger than in the

Urban

Elsewhere.

Among

these regions, the

(22)

magnitude

ofthe trend break corresponds to the deficiencies in hospital access inTable 1: largest in the

urban South followed

by

the urbanrustbelt

and

urban elsewhere. Finally,

we

notethat the largest

black-whitetrendbreakafter 1965

was

forMississippi,

where

accessgaps

were

greatest.

After 1965,both whites

and

blacks enjoyed

improvements

inneonatal mortality, althoughblacks'

gains

were

larger. Interestingly, the closing of the racial gap

was

roughly equivalent across the four

regions. Further, for blacks in

Urban

areas outside the South, the post-1965 reductions in neonatal

mortalityexceededthe post-neonatal ones.^^ Forpresent purposes,

we

note thatthelargest reductions in

both mortality

and

black-white gaps

were

achieved during the post-neonatal period,

and

that the

magnitude

ofpost-neonatal

improvements

corresponds toavailable

measures

ofhospitalaccess.'"

D. TrendsinBlack-WhiteInfant MortalityRates by

Region,

by

pneumonia

and gastroenteritis.

As

noted,

we

isolate these deaths because they

were

Because

the data reporting cause of death are available

beginningin I960,''

Estimates in

columns

(2c) indicate that largereductions inpreventable deaths occurred in

the South that

dwarfed

improvements

for whites. Moreover, the decline in deaths due to these causes accounted for roughly two-thirds ofthe entire relative decline in the post-neonatal mortahty gap.

The

pattern forMississippiis similar. Thus, althoughgastroenteritis

and

pneumonia

accountedforunderhalf

^'

A

comprehensive

accounting ofneonatal mortality trends (especially inMississippi) is beyondthe scopeofthis

paper,howevertheyarelikely tobeatleastpartiallyduetotheinitiationoftheFood Stamps program

(Almond

2006a) and theextension ofthe Maternal and Infant Care

Component

ofthe Maternal and Child Health Services

Program (Chay andGreenstone 2000; Gold,etal. 1969;Sokoletal. 1980;PeoplesandSiegel 1983;Chabot1971).

Chay

and Greenstone (2000)

show

that this measureofaccesswas increasingintheyears priorto 1965 for rural

southernblacks, but this trend acceleratedafter 1965. In regression specifications analogous to those underlying

Tables 2 and 3 for the fi-action ofbirths in hospitals, the estimated post-1965 trend break for blacks in therural

South is large and significant.

To

the extent that this measure reflects the availability ofhospital care to black

infants after 1965, this availability improved at the time

when

post-neonatal mortality rates for Southern blacks

For 1959-1970,

preceding

B. AlternativeExplanations

For another factor to explain the post-neonatal mortality results, it

would

have

to exert an

immediate

effect

on

post-neonatal deaths (especially

among

preventable causes)

and

vary across

Mississippi counties in the

same

way

as the

Medicare

certification dates.

These

are

demanding

criteria.

Nevertheless, this subsection briefly considers alternative explanations for the paper's findings, in

particular the

major

changes in social welfare

and

public health

programs

resulting

from

the

War

on

Poverty.

The

Medicaid

program, initiated in 1966, provided

money

to poorer families for medical care.

However,

Mississippi did not begin its participation in

Medicaid

until January 1, 1970,

by

which

time

most

ofthe reductions in black post-neonatal mortality in Mississippi

had

already occurred. Similarly,

overthis period the

AFDC

program

appears to

have

played a

much

smallerrole in Mississippi than in

otherstates.'"

Moreover,

our event-studyestimates are essentially

unchanged by

adjustment for

county-leveltransferpayments,includingboth

AFDC

and

Food

Stamp

payments.''^

and

MCH

expenditures (per

child) in Mississippi

were

less than half the national average in 1969 (Davis

and

Schoen

1978:146).''^ Also, whilethe proliferationof

community

health centers duringthe 1970s has

been

found

to decreaseinfantmortality, especially

among

blacks, there

were

only 51 such centers inthe entirenation

as of 1968

(Goldman

and

Grossman

1988). Further,

community

health centers did not provide the

aggressivemedical treatmentthat

would

have

been

required

by

infantswith

pneumonia and

diarrhea.

Finally, changes in birth technology

do

not coincide with the timing of the infant mortality

reductions forblacks in Mississippi (see footnote 22).

Moreover,

technological innovations are widely

thought to impact early infant death resulting

from

premature

and

low

birth weight births,

which

is not

consistent with the striking reduction in preventable post-neonatal infant deaths

among

blacks in

Mississippi.

In

summary,

we

areunabletoidentify a viablealternative explanation fortheevent studyresults.

Our

conclusion

from

the Mississippi data is that the federally

mandated

integration of health care

facilities played a central role in the sharp decline in blacks' post-neonatal mortality rates.

To

put the

results in

some

context, the Table 3 estimates imply thatjust 6 years after successful integration,

V. Interpretation

How

large

was

the mortality reduction caused

by

mandated

integration

and

what

was

the

associated welfare gain?

Answering

these questions requires additional assumptions, but informs the

importance of the health effects here

documented and

how

they

compare

with effects

from

other

government

interventions.

The

case for a causal impact of

mandated

integration is strongest in the rural South (where

ex-ante access disparities

were

greatest)

and

for causes of death

known

to be treatable in hospitals.

lowerin 1967,

and

soon untilit

was

6.6 deathsper 1000births lowerin 1975.

The

multiplication ofthese declines in the

PNMR

by

the annual

number

of blackbirths in the

rural South implies that roughly 4,700 additional survived

from

age 1

month

to age 1 year during the

years 1965-1975

and

25,300 infants

from

1965-2002.'*'' Alternatively, it

may

be reasonable toascribe the

entire post-1965 trend break inpost-neonatal mortality (i.e. post-neonatal deaths

from

all causes) to the

mandated

integration. Inthis case,these

numbers

would

rise to 7,100

and

38,600, respectively.''^

These

calculations suggest that the

mandated

integration of hospitals in the rural South accounted for

16%

(based

on

preventable causes only) or

25%

(based

on

all post-neonatal fatalities) ofthe national 7.5 per 1,000declineinthenationalblack

PNMR

between

1965

and

1975.

An

alternative

means

to assess the

magnitude

ofthese gains is to ask

how much

blacks in the

rural South

would

have

been

willingto

pay

(WTP)

forthese reductionsininfant mortality.''^

To

develop

an estimate of

WTP, we

use Ashenfelter

and

Greenstone's (2004) upper

bound

estimate of $1.9 million

(2005S)asthe valueofa statistical life(VSL)."*'

With

thisvalue

and

a

3%

discountrate,

we

estimate that

blacks in the rural South in 1965

had

a

WTP

for the reduction in infantmortality that occuired

between

1965 and 1975 of$7.3 billion (forpreventable cause post-neonatal fatalities)

and

$11.1 billion (for all

cause post-neonatal mortality).

Among

all black residents ofthe rural South, the

WTP

per

capita

was

$1,400

and

$2,100 (for preventable

and

all-cause

PNMR

reductions, respectively). If

we

keep the

reduction inblackpost-neonatal deaths constantatthe 1975reduction for the

1975-2002

period, there are

additional gains of $20.1 billion (preventable causes)

and

$30.8 (allpost-neonatal causes) for the

(Garrow 1986 andCaro 2002). Additionally, itmight beappropriate to addthe reductioninthe black-white post-neonatal mortalityrateintheruralSouth,althoughthiseffect isn't statistically significant. Therewerealsopre-1965

These

in infant mortality likely underestimate

(potentially substantially) a

VI.

Conclusions

Passage ofTitle

VI

ofthe Civil Rights

Act

marked

a reversal offederal policy with respect to

race. Inprohibiting discrimination

and

segregationin allinstitutionsreceiving federal funds,

and

through

its vigorousenforcement

by

the

Johnson

Administration, blackaccess to hospitals intherural South

was

quickly

and

dramatically expanded, withlargebenefits interms ofinfant lives saved.

We

conclude that

the benefits of 1960s Civil Rights legislation extended

beyond

the labor market

and

therefore are

substantially largerthanhas

been

recognizedpreviously.

These

findings are relevant for current discussions regarding the efficient allocation of public

resources in developing countries.

More

than a third ofchildren in

low-income

countries

do

not receive

treatment for acute respiratory infections and only half receive proper care for diarrhea (Jha et al.,

2002:2037). This paper illustrates that health treatments are sought out

when made

available

and

can

and immediate

benefits.
