The data in the South African Census 2001 dataset is a 10% unit level sample drawn from Census 2001 as follows:
1) Households:
• A 10% sample of households in housing units, and
• A 10% sample of collective living quarters (both institutional and non-institutional) and the homeless.

2) Persons:
• A sample consisting of all persons in the households and collective living quarters, and the homeless, drawn for the samples described above

3) Mortality:

Research instrument
---------------------------

Three questionnaires were administered for the South African Census 2001, questionnaire A (for persons in households), questionnaire B (for persons in institutions) and questionnaire C (for institutions). The Household questionnaire covered household characteristics, such as dwellling type, home ownership, household assets, access to services and energy sources. A component of the questionnaire captures fertility data. Both the household and persons in institutions questionnaires collected data on individuals' characteristics, including age, population group, language, religion, citizenship, migration, mortality and disability, as well as means of travel. Economic characteristics of individuals included employment activities and data on unemployment.

Data appraisal
---------------------------

As part of the quality check for Census 2001, a Post-Enumeration Survey (PES) was conducted in November 2001, approximately one month after the census. Fieldworkers re-visited a scientifically selected sample of almost 1% of the census enumeration areas, to do an independent recount. The published census results are adjusted for undercount according to the findings of the PES. In addition to the check on coverage, the PES also involved an independent re-measurement of the basic characteristics of the population. Details on this process are available in the publication:

数据评估
---------------------------
作为普查2001年质量检查的一部分，于2001年11月进行了人口普查后的调查（PES），在大约一个月后。调查员重新访问了科学选定的几乎1%的普查登记区域，进行独立重计。发布的普查结果根据PES的发现对低估进行了调整。除了覆盖范围的检查外，PES还涉及对人口基本特征的独立重新测量。关于此过程的详细信息可在以下出版物中找到：
