Compilation of Vital Statistics at International Level Session 13
Outline • Introduction • UN Demographic Yearbook • How complete are the data sent from countries? • Importance of collecting and providing data • Why are some countries not complying? • Level of response and quality of data provided to DYB • Ways forward
Introduction • The international data collection process is based on sending a set of questionnaires to national statistics authorities. • This process depends on the replies received from countries. • The major vehicle for international dissemination of national population and vital statistics is the UN Demographic Yearbook (DYB).
Demographic Yearbook (DYB) • 6 questionnaires: • Population estimates • Vital Statistics • International migration and travel statistics • Population census • Population census – economic characteristics • Population census – household characteristics Yearly When a census has been conducted
Demographic Yearbook (DYB) • Vital Statistics (VS) questionnaire: • Comprehensive collection of tables distributed in 10 sections: 1. VS summary by urban/rural residence for the last 5 year 6. Infant deaths (deaths under 1 year of age) 5. Deaths 3. Fertility 4. Life Tables 2. Live births for the last 5 year 7. Late foetal deaths (deaths of a foetus of at least 28 completed weeks of gestation 8. Legally induced abortions 9. Marriages 10. Divorces
Demographic Yearbook (DYB) • Other characteristics of VS questionnaire: • New format – pre-filled with available data • Protected against changes to avoid changes in format which can impair data processing • In case of gaps or old data in need to be revised, an extra file can be attached (DYB personnel will process it on an individual basis)
Demographic Yearbook (DYB) • Handout: list of tables in questionnaire, coding scheme
Demographic Yearbook (DYB) • Metadata: • Table called “coding scheme” requesting information of the quality of vital statistics being sent to DYB • Date of occurrence vs. Date of registration • Estimated completeness of registration (>90%, 75-89%, 50-74%, 50%>) • Year to which metadata refers • Basis of completeness of estimate (Demographic analysis, dual record check, other) • None of the ESCWA countries fill in the metadata “coding scheme”
Demographic Yearbook (DYB) • Sources of variation of data reliability (and thus affecting international comparability): • Completeness and accuracy of the data produced by a national registration system vary from one country to another. • In some cases, the registration system covers only certain vital events. • Differences in the effectiveness with which laws pertaining to civil registration are implemented – degree to which the public complies with legislation
Demographic Yearbook (DYB) • Sources of variation of data reliability (and thus affecting international comparability): • Some statistics of marriage and divorce are obtained from sources other than civil registers, e.g. church registers, court registers. • Differences in statistical definitions of vital events. • Differences in geographical and ethnic coverage of the data. • Diverse tabulation procedures • Some VS are official estimates, frequently from sample surveys, subject to non-sampling errors, sampling errors and completeness issues.

Importance of collecting and providing data • International comparability • Enabling of social studies to test hypotheses • Informed public policy decisions • Better representation of countries in the international setting
Why are some countries not complying? • Information not collected within the country • Information collected within the country, but not reported to UNSD • Information collected and reported but with such a low quality that it cannot be published
Level of response and quality of data provided to DYB • There’s a good level of response within ESCWA region for general tables • But not so good for detailed tables. • E.g. Oman, Kuwait, Lebanon, O. Palestinian T., Saudia Arabia, Syrian A. R. and Yemen provide general live births table but not break down by birth order • Quality • Gaps in historical data
Discussion of ways forward • The DYB seeks to promote the dissemination and utilisation of national data at the international level. • How to improve level of response from countries to DYB? • Factors endogenous to DYB • Factors associated to national circumstances and civil registration system • How to improve quality of data provided to DYB? • What are the benefits to countries of responding to the DYB system?
Still pending • How well are countries complying with the international standard? • How many countries comply with intl. standards? – Haoyi • Make maps to show which countries provide which data
