History of Census Taking in Zambia Pre Independence 1911 - First Census but covered non Africans only Other Census that followed were in 1921, 1931, 1946, 1951, 1956 and 1961 (All non African) No count of African was made during the period Estimates of Africans were based on the tax Payers Register First attempt to count Africans was through a Demographic Sample Survey which was conducted in 1950
Just before Independence, there was need for a complete Census thus the first Census which included Africans in 1963. Post Independence So far Five Censuses have been conducted in 1969 (4, 661, 331), 1980 (5, 661, 539), 1990 (7, 759, 117), 2000 (9, 885, 591)and the just ended 2010 (Preliminary Figure of 13, 046, 508).
Availability of Census Data Complete Census raw data files are accessible outside the Zambia Statistical i Office The Office provides 10 percent of the data set to the general public upon request A few Universities such as the University of Zambia, Pennsylvania State (African Census Project) and the University of Michigan have been able to access the full sets with strict t conditions and for Academic purposes only.
Availability of Census Data Data is normally ygiven out in the ASCII format with a corresponding Data Dictionary The Dissemination of Results in done though Reports or Publications CDs Website
Census Documentation Enumeration Forms 1969 - Single form used to collect data 1980 Single form used but it had some characteristics on Fertility, Economic Activity and Housing collected from all urban areas and some selected rural areas. 1990 Single form used, but had an Agriculture module attached which was used to create a frame for the Subsequent Agriculture Census
Census Documentation Cont. 2000 Two forms were used 1. Household form 2. Individual Form 2010 A single form was used to collect both the Household characteristics and information on the Individual Data for all Censuses is electronically captured
Documentation After data capture, the office undertakes to document the Census process and instruments Since 2009, CSO has been implementing a National Data Archiving (NADA) System. So far 25 Surveys including two Censuses have been archived. NADA can be accessed through a link to the CSO website which is www.zamstats.gov.zm
Documentation cont. Census Instruments The documentation includes Census instruments and this has explanations on all the questions More detailed explanations are given on topics such as Education and Economic Activities. Codebooks: Zambia has not produced any codebooks so far. The various codes used in the Censuses are normally attached to the Enumerator s instruction manuals.
Documentation Cont. Technical Reports and data processing 1969, 1980, 1990 and 2000: All the Censuses have analytical l reports in publication form and these reports are maintained by the office. In the past, there was no systematic documentation on the edits and imputations specification, but for the 2010, the documentation is being done and will produce a user guide on edits and imputations performed on the data
History of Micro Data Zambia undertakes Traditional Censuses, that is personal visits by Enumerators to households The scope of work is normally 100 percent Collects both De Jure and De Facto population A key respondent is identified in each household Period of collection in on average 1 month Forms are brought to Centre within a month of completion
Contents of Micro Data The Census Micro Data includes: Identification variables (Province, District etc) Household structure t (membership status) t Demographic and social variables International Migration Education Economic Activities Fertility and Mortality Civil Registration Household and Agriculture variables
Harmonization All the Censuses have tried to International recommendations as much as possible In 2010 the following publications were heavily used Principles and Recommendations for Population and Housing Censuses, Revision 2 p g, Handbook on Census Management for Population and Housing Censuses,
Harmonization cont. Handbook on Population and Housing Census Editing, The Census Data Capture Methods and S the Post Enumeration Surveys The use of International recommendations has made it possible to compare the Censuses although there are some variations in some instances
Sources of Variations Geographical re-demarcations Revisions made internationally on certain concepts (e.g. definition of household member) Changes in the certain systems within the country (e.g. education system) Variations that relate to expansions of categories (e.g. Relationship to head, Marital Status, Disability, etc)
Completeness of the Enumeration p Efforts are made to have a 100 percent count Some measures are being used to assess the coverage errors e.g. currently the Post Enumeration Survey for the 2010 Census is being implemented Completeness Publications The reports produced include the Descriptive tables, analytical l reports, Thematic reports etc.
