Comparative National Elections Project, South Africa 2015 - South Africa

Abstract
---------------------------

This dataset is the election survey conducted in South Africa by Robert Mattes of the Democracy in Africa Research Unit at the University of Cape Town in 2015. The survey collects data using standard questions from two international election studies, the Comparative National Elections Survey (CNEP), and the Comparative Study of Electoral Systems (CSES). The Comparative National Elections Survey is coordinated by the Mershon Center for International Security Studies at Ohio State University (https://u.osu.edu/cnep/). The Comparative Study of Electoral Systems is a collaborative program of research among election study teams from around the world, run by the Center for Political Studies and GESIS, Leibniz Institute for the Social Sciences, in Germany, and the University of Michigan in the US (http://www.cses.org/). The South African study includes additional questions. The study and the earlier 2004 CNEP for South Africa are part of a series of South African surveys conducted by DARU, called the South African National Election Study.

Geographic coverage

The universe of the study is citizens in South Africa.

Kind of data
---------------------------

Sample survey data

Sampling procedure
---------------------------

The survey used a random, nationally representative, stratified, area probability cluster sample. Primary sampling units were census enumerator areas (EAs) selected as a random sample, with probability proportionate to population size. All EAs were stratified by 1) Province, 2) Urban/Rural and 3) Race. Within each EA, a skip interval of 10 dwellings to select a household was used. That is, walking in a designated direction away from the start point, selecting the 10th household for the first interview, counting dwellings on both the right and the left (and starting with those on the right if they are opposite each other). Once the household was chosen, the interviewer randomly selected an individual respondent within the household to be interviewed (altering gender quota). The total number of household in the sample was 1300.

Sampling deviation
---------------------------

If the household was vacant, if the household refused to participate, if the selected person refused to be interviewed, or if the selected respondent is not available after two callbacks, interviewers were instructed to move to the next house in the walk pattern (i.e. every tenth house). They were not permitted to substitute within a household

Mode of data collection
---------------------------

Face-to-face [f2f]

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

The survey collected data using core questionnaires from both the Comparative National Elections Project and the Comparative Study of Electoral Systems, as well as a separate questionnaire developed by DARU.

Cleaning operations
---------------------------

The data was checked and cleaned by the original team at the Democracy in Africa Research Unit. DataFirst undertook further cleaning on the data, including the consolidation of data documentation.

Response rate
---------------------------

The response rate for the survey that the CSES Module appeared in was 34%.

摘要
---------------------------
本数据集为2015年由南非开普敦大学非洲民主研究单元的罗伯特·马特斯所进行的选举调查。调查采用来自两个国际选举研究项目——比较国家选举调查（CNEP）和比较选举系统研究（CSES）的标准问题收集数据。比较国家选举调查由俄亥俄州立大学梅西恩国际安全研究中心（https://u.osu.edu/cnep/）协调。比较选举系统研究是全球选举研究团队之间的合作研究项目，由德国政治研究中心和莱布尼茨社会科学研究所以及美国密歇根大学共同运营（http://www.cses.org/）。南非调查包含额外问题。本研究以及2004年的早期CNEP南非调查是DARU（非洲民主研究单元）进行的南非国家选举调查系列的一部分。

样本调查数据
抽样程序
---------------------------
调查采用随机、全国代表性、分层、按区域概率聚类样本。主要抽样单位为随机选取的普查区（EA），其选取概率与人口规模成比例。所有EA按1）省份、2）城市/乡村和3）种族进行分层。在每个EA内，使用10户间隔选择一户进行访谈。即，从起点出发沿指定方向行走，选择第10户作为第一次访谈对象，计算左右两侧的住宅数量（如果它们相对，则从右侧开始）。一旦选择了家庭，调查员将随机选择家庭内的一个受访者进行访谈（调整性别配额）。样本中的家庭总数为1300户。
抽样偏差
---------------------------
如果家庭空置、家庭拒绝参与、选定的个人拒绝接受访谈或在两次召回后选定的受访者不可用，调查员被指示按照行走模式（即每第十户）移动到下一户。他们不允许在家庭内部进行替代。
数据收集方式
---------------------------
面对面访谈 [f2f]
研究工具
---------------------------
调查使用比较国家选举项目和比较选举系统研究的核心问卷，以及由DARU开发的单独问卷收集数据。
数据清洗操作
---------------------------
数据由非洲民主研究单元的原团队进行了检查和清洗。DataFirst对数据进行进一步清洗，包括数据文档的整合。
应答率
---------------------------
包含CSES模块的调查的应答率为34%。
