Workshop on Improvement of Civil Registration and Vital Statistics in SADC RegionBlantyre, Malawi, 1 - 5 December 2008
Introduction The UN international data collection
process is based on sending a set of questionnaires to national statistics authorities.
A great deal of 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)
New characteristics of VS questionnaire: Pre-filled with available data from past years
for each country Password protected to avoid changes in
format which can impair data processing and validation
Currently being revised to reduce burden on countries

Demographic Yearbook (DYB) Metadata:
Table called “coding scheme” requesting information of the quality and methods of vital statistics being sent to DYB
None of the SADC countries filled in the metadata “coding scheme” in this year’s data collection

Demographic Yearbook (DYB) Sources of variation in 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 statistical definitions of vital events.

Demographic Yearbook (DYB) … Sources of variation of data reliability
(and thus affecting international comparability): Differences in geographical coverage and
national groups. Diverse tabulation procedures Official estimates, frequently from sample
surveys: subject to sampling errors, non-sampling errors and completeness issues.

There’s a fair response within SADC region for general mortality and natality data.
But it is low for the rest of subjects. E.g. Malawi, Namibia, Swaziland, Zambia and
Zimbabwe provide mortality and natality tables but no other subjects
Quality Gaps in historical data
Response and quality of data provided to DYB
Workshop on Improvement of Civil Registration and Vital Statistics in SADC RegionBlantyre, Malawi, 1 - 5 December 2008
Informed public policy decisions Enabling of social studies to test
hypotheses Better representation of countries in the
international setting International comparability Global dissemination of data by UNSD
Importance of collecting and providing data
Workshop on Improvement of Civil Registration and Vital Statistics in SADC RegionBlantyre, Malawi, 1 - 5 December 2008
Information not collected within the country
Information collected within the country, but not reported to UNSD
Information collected and reported but because of lack of metadata, it cannot be published
What are the challenges for providing data?

How to improve level of response from countries to DYB?
Factors endogenous to DYB Factors associated to national circumstances and civil registration system
The DYB seeks to promote the dissemination and utilisation of national data at the international level.
How to improve quality of data provided to DYB?
What are the benefits to countries of responding to the DYB system?
Discussion of ways forward
