In October 2001, South Africans were enumerated to collect information on persons and households throughout the country, using a uniform methodology.
Household data collected included data on each household and each person present in the household on Census night, as well as data on services available to the household. Data on household residents, and residents of hostels and the other types of collective living quarters was also captured, as well as data on individuals who spent census night in institutions and hotels.

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:
• A sample consisting of all mortality information for the households in housing units drawn in the 10% sample of households.

Face-to-face [f2f]

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
---------------------------
作为二零零一年普查质量检查的一部分，于二零零一年十一月进行了一次人口普查后的调查（PES），在大约一个月后。调查员重新访问了科学选择的近1%的普查登记区域，进行独立计数。根据PES的调查结果，对已发布的普查结果进行了低估调整。除了覆盖范围检查外，PES还涉及对人口基本特征的独立重新测量。有关此过程的详细信息可在以下出版物中找到：
