one or more specific stages of his life cycle. Working life

migrants are migrants who spend their entire working lives in the city but intend, and eventually do, retire to their home village.

A permanent migrant is committed totally to exchanging a rural for an urban way of life. An undecided migrant has no clear intentions

either to stay in the city, or to return to the village.

11. The complexities connected with these concepts and definitions in practice render migration measurement, data collection and comparisons difficult.

III. DATA COLLECTION

12. The principal sources of data on both internal and international migrations are population censuses and demographic sample surveys. Other sources are administrative records and population registers.

13. The internal migration data from censuses and surveys are of two types, the 1st type are data obtained through direct questions on related topics and data derived indirectly trom census questionnaires not necessarily collected for the purposes of measuring internal migration. The 2nd type come from net internal migration estimates derived from the difference in the population counts in two censuses.

14. The four types of direct questions most often used to derive

information on migration censuses are: place of birth, place of

last residence,- duration of residence in the place of enumeration

and residence on a specific date before the census. Information

derived from surrogate measures such as age and sex distributions is predicated on the assumption that the movement is selective with respect to these variables. Thus, area variations of these variables enable conclusions to be made on. rates of mobili ty, subject to some reservations: age and sex distributions also depend on other components of population change such as fertility and mortality. The part attributable to migration after taking into account natural increases is difficult to evaluate in most African countries because birth and death rates are not known with certainty.

15. The indirect methods of internal migration estimation have

been classified into two broad types by shyrock and associated (in

the methods and materials of demography) as:

(a) National Growth Rate method

(b) Residual method comprising the vital statistics method and the Survival ratio method.

The full discussion on the methods of measuring internal migration has been done under the agenda item 7 and also can be found in the

E/ECA/STAT/WG/MS/8 9/ll

document ECAr Statistical Information bulletin for Afr

16. The sources of international migration data are

those of internal migration„ The administrative records^{the same}are^{? ?} sources for the direct measurement of international mi

include entry/departure cards or forms completed at ir

borders, residence/work permits issued to aiip

ica, n° 1

gration and ternation^l general

population registers and registers of aliens. Frontier control

data are generally most important source of international

migration statistics, but in many African countries tjhe frontier

control records are too deficient to provide Satisfactory

indications. Thus population censuses and/or sample purveys are the major sources of the available statistics on th£ stock and characteristics of international migration, '

17. There are differences between international migration data obtained, in census or survey and the data compiled friom frontier

control records: I

Frontier control records provide the total jof arrivals

and departures on a continuing basis. j

Census or survey data do not provide the tot^l volume of immigration since they do not include those who died or

returned to their countries of origin or| places of

previous residence before the census reference period.

nor do they provide information on emigration.

Census and survey data, unlike the administrative

study of the characteristics

distribution within a country,

13, Census data on international migration are obtained on tl:e basis of census questions on place of birth, nationality or country of citizenship, place of last previous residence or residence at a specified past period and duration of residence lor year ~f

19. The major difference between the use of census o\r

source of data on international migration is that a ! census c^n provide data for small areas but it is not a suitable1 source f•-■r

detailed information such as reasons for migration. On the oth-rr

hand though a national sample survey cannot provide Ismail areas

statistics, it offers a suitable means for in-depth study of

international migration. !

20. The collection of data on both internal and international

migration in Africa is seriously affected by the non uniformity on

concepts, definitions and classification. Because thelse data are

often based on different definitions and collection syjs terns, it

E/ECA/STAT/WG/MS/3 9/11 Page 5 is difficult, and sometimes impossible to compare data on migrant f low^ between oa.i v of countriss -

IV. ISSUES ON MIGRATION STATISTICS

21. Within the framework of even a restricted concept- of migration as given earlier, there are a number of subsidiary conceptual and procedural problems because one cannot- give each term a wholly

precise meaning; on the other hand, a lor. of compromises have to

be made between the ideal and the feasible in the real world of

empirical research. The above definition for migration indicates that short moves - from one apartment, to another in the same-

building or in the same lawn - are not considered. Only moves of some reasonable minimum distance should qualify as migrations.

Although the tabulation of moves by distance covered is obtainable with exact information on points of origin and points of

destination, it is a difficult and laborious process to produce

this kind of detail. Operationally, a migration is often defined

as a change of residence from one civil division to another; then,

given that, civil divisions of the same class vary widely in size, shape and length of border, it is clear that this criteria for

identifying migrants lack uniformity,

22. Persons who move during a migration interval and died should, strictly peaking,- be counted as migrants and their moves should be counted as migrations. However, since information on migration is

usually obtained after the end of the interval and from persons

still living at that time, both the number and the moves of

migrants who died in the interim are likely to be excluded.

23. In applying the definition of international migration given above in some African countries, difficulties arise because a large

number of boundaries were demarcated during the colonial period

without regard to whether or not they divide ethnic groups. Many types of mobility from rural to urban involve the crossing of international boundaries without, reference to the™. Also F because

of the extensive lengths of the boundaries, most not protected by

natural terrains, and because of the frequency of the movements, it has not proved feasible to record all movements across thsm.

24. In international migrations, data based on the intended or actual length of stay or absence enables classification, but. in many cases, intention do not materialise and stated intentions about length of stay are not recorded, do not always coincide with actual length of stay,

25. ■ The question on birthplace is the source mostly used by

African countries to gather information on migration and for classifying birth-places as rural or urban, and people as migrant

DATA BASE

1 ■ Objectives

31. The economic commission for Africa St.at.isr.ics Division ^ n collaboration with substant-ive divisions of ths orqanizatioR n~s

established an integrated statistical data base containing social, demographic and economic data. This data base is an information system where statistical data are compiled, processed and

disseminated. The main objectives of the data base are:

1. To compile statistical data in a computerized form, 2. To provide ECA statisticians, economists,- and

demographers with direct and speedy access of African statistical data and to provide them with data processing and analysis services.

3. To automate the publi cations of ECA!s statistics 1

information.

4. To disseminate comprehensive and up-to-date statistical information to users including data collected from various international data banks.

5. To provide assistance services to member countries wc.o plan to set ur> statistical data banks.

6. To give users other types of services which are required

fro

2. Organization

32. The ECA statistical data base is organized in three levels of data bases integrated into one system of information. The level

I data base is a country profile which produces a snap shot vi -.w of the socio-economic condition of any one African country or

region. Level II contains the bulk of detailed statistical d?ta

using standardized international classi f ications . concepts . a net definitions. The data being voluminous.- is kept off-line en

magnetic tapes and is used on demand or as input to update levels

I and III. The level III data base contains selected time series data for on-line application which is capable of answering the most

frequently sought data.

3. T mple™entation

33. The implementation of level I depends on levels II and ITr,

To date this data base is not implemented. For level II, fors^n

trade statistics and national accounts data are operational. The foreign trade data using the Standard International Trade

E/SCA/STAT/WO/MS/8 9/11 Page 8

Classification, contains over 20 million entries on magnetic tapes.

There are over 25,000 national acconnr.s dara ir^inding s^cto^l

deflators.

31, The level III data base is time series containing data valu^

for up to 26 years from 1965 to 1990 for a given statistical series. The data contained are for aggregates and selected item-:, which are frequently souaht by users. The "African Statistic?1- Yearbook", "African Socio-economic Indicators", "Foreign Tra^-r Statistics for Africa: Summary Tables Series C:', "Foreicrn Tra^-:

Statistics for Africa: Direction of Trade Series A". tr^

Statistical tables for the "Survey of Economic and Social Conditions in Africa" and various country tables are produced frc^

the level IIi data base.

35. To date the level III data base contains over 151,000 tim^

series data on trade, national account,?, acriculture, industr"-

price , population .. health , educata on , labour , finance . transpor- and communication and vital statistics. Each data is identified by statistical series identifier - Depending on the type or' statistic.?, other parameters are also used to uniguely identify th-L- data series. These are the mode of observation, the reporting

country, the partner country. and the base vear, The *>ode c r

observation is used to give more description or the characteristic^

of the series as each statistical dories could be observed differently. Each statistical data is flagged by a footnote to indicate in broader terms the source and type of data as official national data, estimates by the reporting country, provisional

data, etc.

36. The bulk of statistical data is contained in one detail data

file and more description of the pertinent data fields, series identifier, mode of observation, the reporting country, partner

country and the unit of observation are contained in the other data

files. The detail statistical data set is linked to these master

data files via the series identifier, mode of observation

reporting country, partner country and the unit of observation

codes or variables. These fields are also used to identify da^-a entries in the different data sets,

31 . The level III aata base is bui ix and. maintained using Imaae 3000 data base management system a product of Hewlett-Packard and custom written programs. Imaae 3000 is used to define, create . access and maintain the data base.

38. Custom written programs, are developed to fill the gap between

the requirements of the statistical data base and the features-

available with Image 3000 data base manaaement s-'ste^.

VI. ESTABLISHING A STATISTICAL DATA BASE ON MIGRATION

1. Ob "i e c t i v e s

39. The most, fundamental goal in developing a migration statistics data base in a country or reerier- is to supply policy makers, programme planners and researchers with statistics on internal and

international migrations. The data base should be used in an

integrated —anner to exolain the outcome of the economic and social policies at all desired levels.

40. The migration statistics data base is an information system

where users are able to enter data which could be retrieved at will

and obtain information in respect of users demand. The data base will have a system of classification for migration statistics according to international classification of migration, concepts and definitions. The system of classification proposed for the data base is shown in Annex I, This classification can be fully developed for each African country.

41, In general the main classifications for migration statistics

are: -

1. Internal migration

- Inter-Urban migration (Rural and Urban migration) - Met migration per specific area

- No. of migrants by sex and age

- No. of !r.iaranr.s by kind of economic activity

- No. of migrants by reason for leaving (cause of migration

- Mo, of in and out. migrants by sex and age ion.

) Total No. of immigrants

f immigrants by sex and acrey s

- Mo. of immigrants by kind of economic activity - Mo. of immigrants by reasons for leaving (cause of

migration;

- No, of emiarants by sex and age

- Mo, of emigrants by kind of economic activity - Mo. of economicca1y active emigrants by sex 3. Total financing of migration.

42. The migration statistics data base will contain country data according to standard logical record structure maintaining the Sim.ilar to the organization of the Economic Commission for Africa Statistics! Dar.e Base. r.ni s -da t a baT v could be organized in different da-a files. The detail numerical data could be time 5.= ?-i^5 dar.e bui 1 r in one dar.a file, Each locrical record contains

- The — 1 gr a7" ion s t ar-is ^ ics classification code

- Additional info?:"mat!on on how the series is defined such as sex. growth rate etc. (the mode of observation)

- The countr" or reaion of the oriain of the miarant - The country or reaion of destination of the migrant - The unit of measurement

A series of numerical data value along with some descriptors to identify if the data is actual official, provisional, estimated, projected etc.

43. In addition to these variables other variables such as the vear or raria~ of vears for which the data is recorded, the date of update r the base year if appli cabi e, etc are also included.

44. The other data files wii1 contain the most relevant variables along with their full r.ext description in both English and French.

These files "ive the description of

- The Statistical series - The mode of observation

- The reportina country or reaion or the oriain of the migrant - The destination counrry or region of the migrant whenever

a p xy • i_ o a b 1 e and

45. These files are hierarchical!y connected to the numerical data file usina the same variables. This type of hierarchial organization will conserve storage space and enable fast retrieval of data. The variables used in these data files are used as search items to retrieve the numerical data. These files also give the necessary full description of the statistics.
