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).

4
Demographic Yearbook (DYB)

• Questionnaires
• Population estimates
• Vital Statistics
• Population census
• General characteristics
• Economic characteristics
• Housing
• Household characteristics
• International Migration and travel

Yearly
When a census has been conducted
Pilot test
5
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 rates
4. Life Tables
2. Live births
8. Legally induced abortions
9. Marriages
7. Foetal deaths and Late foetal deaths
10. Divorces
6
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

7
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 years data collection

8
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.

9
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.

16
How complete are the data sent from countries?

• Last 10 years

17
Response and quality of data provided to DYB

• Theres 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

18
Importance of collecting and providing data

• 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

19
What are the challenges for providing data?

• 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

20
Census

• Questions recommended on Vital Statistics (core
  topics)
• Children ever born alive
• Children living
• Date of birth of last child ever born alive
• Household deaths in the past 12 months

• 2007 Swaziland Census
• Household deaths in the past 12 months

24
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?
