Afrobarometer Survey 2019 - Guinea

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

The Afrobarometer is a comparative series of public attitude surveys that assess African citizen's attitudes to democracy and governance, markets, and civil society, among other topics. The surveys have been undertaken at periodic intervals since 1999. The Afrobarometer's coverage has increased over time. Round 1 (1999-2001) initially covered 7 countries and was later extended to 12 countries. Round 2 (2002-2004) surveyed citizens in 16 countries. Round 3 (2005-2006) 18 countries, Round 4 (2008) 20 countries, Round 5 (2011-2013) 34 countries, Round 6 (2014-2015) 36 countries, and Round 7 (2016-2018) 34 countries. The survey covered 34 countries in Round 8 (2019-2021).

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

Afrobarometer uses national probability samples designed to meet the following criteria. Samples are designed to generate a sample that is a representative cross-section of all citizens of voting age in a given country. The goal is to give every adult citizen an equal and known chance of being selected for an interview. They achieve this by:

• using random selection methods at every stage of sampling;
• sampling at all stages with probability proportionate to population size wherever possible to ensure that larger (i.e., more populated) geographic units have a proportionally greater probability of being chosen into the sample.

The sampling universe normally includes all citizens age 18 and older. As a standard practice, we exclude people living in institutionalized settings, such as students in dormitories, patients in hospitals, and persons in prisons or nursing homes. Occasionally, we must also exclude people living in areas determined to be inaccessible due to conflict or insecurity. Any such exclusion is noted in the technical information report (TIR) that accompanies each data set.

Sample size and design
Samples usually include either 1,200 or 2,400 cases. A randomly selected sample of n=1200 cases allows inferences to national adult populations with a margin of sampling error of no more than +/-2.8% with a confidence level of 95 percent. With a sample size of n=2400, the margin of error decreases to +/-2.0% at 95 percent confidence level.

The sample design is a clustered, stratified, multi-stage, area probability sample. Specifically, we first stratify the sample according to the main sub-national unit of government (state, province, region, etc.) and by urban or rural location.

Area stratification reduces the likelihood that distinctive ethnic or language groups are left out of the sample. Afrobarometer occasionally purposely oversamples certain populations that are politically significant within a country to ensure that the size of the sub-sample is large enough to be analysed. Any oversamples is noted in the TIR.

Sample stages
Samples are drawn in either four or five stages:

Stage 1: In rural areas only, the first stage is to draw secondary sampling units (SSUs). SSUs are not used in urban areas, and in some countries they are not used in rural areas. See the TIR that accompanies each data set for specific details on the sample in any given country.
Stage 2: We randomly select primary sampling units (PSU).
Stage 3: We then randomly select sampling start points.
Stage 4: Interviewers then randomly select households.
Stage 5: Within the household, the interviewer randomly selects an individual respondent. Each interviewer alternates in each household between interviewing a man and interviewing a woman to ensure gender balance in the sample.

To keep the costs and logistics of fieldwork within manageable limits, eight interviews are clustered within each selected PSU.

Guinea
- Sample size: 1,200

- Sample design: Nationally representative, random, clustered, stratified, multiple stages, probability sampling
- Stratification: Region, urban-rural distribution
- Stages: Primary sampling unit (PSU), start points, households, respondents
- PSU selection: Probability Proportionate to Population Size (PPPS)
- Cluster size: 8 households per PSU
- Household selection: Randomly selected start points, followed by walk pattern using 5/10 interval
- Respondent selection: Gender quota to be achieved by alternating interviews between men and women; potential respondents (i.e. household members) of the appropriate gender are listed, then the computer randomly selects the individual

Mode of data collection

Face-to-face [f2f]

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

The Round 8 questionnaire has been developed by the Questionnaire Committee after reviewing the findings and feedback obtained in previous Rounds, and securing input on preferred new topics from a host of donors, analysts, and users of the data.

The questionnaire consists of three parts:
1. Part 1 captures the steps for selecting households and respondents, and includes the introduction to the respondent and (pp.1-4). This section should be filled in by the Fieldworker.
2. Part 2 covers the core attitudinal and demographic questions that are asked by the Fieldworker and answered by the Respondent (Q1 – Q100).
3. Part 3 includes contextual questions about the setting and atmosphere of the interview, and collects information on the Fieldworker. This section is completed by the Fieldworker (Q101 – Q123).

Afrobarometer是一项比较性的公共态度调查系列，旨在评估非洲公民对民主与治理、市场以及公民社会等议题的态度。自1999年起，该调查以定期间隔进行。随着时间的推移，Afrobarometer的调查范围不断扩大。第1轮（1999-2001年）最初覆盖7个国家，后来扩展到12个国家。第2轮（2002-2004年）调查了16个国家的公民。第3轮（2005-2006年）覆盖18个国家，第4轮（2008年）覆盖20个国家，第5轮（2011-2013年）覆盖34个国家，第6轮（2014-2015年）覆盖36个国家，第7轮（2016-2018年）覆盖34个国家。第8轮（2019-2021年）覆盖34个国家。

样本调查数据 [ssd]

抽样程序
---------------------------
Afrobarometer采用旨在满足以下标准的全国概率样本。样本设计旨在生成一个代表性样本，该样本反映了一个给定国家所有有投票资格公民的横截面。目标是给每位成年公民一个平等且已知的被选中接受访谈的机会。他们通过以下方式实现这一目标：
• 在抽样每个阶段使用随机选择方法；
• 在可能的情况下，使用与人口规模成比例的概率进行所有阶段的抽样，以确保较大的（即人口较多的）地理单元有更大的概率被选中进入样本。

抽样总体通常包括所有18岁及以上的公民。作为一项标准做法，我们排除了居住在机构化环境中的个人，例如宿舍的学生、医院的病人以及监狱或养老院中的人员。偶尔，我们也必须排除由于冲突或不安全而确定为不可到达的地区居住的人员。此类排除情况将在伴随每个数据集的技术信息报告中注明。

样本规模和设计
样本通常包括1,200个或2,400个案例。随机选择的n=1,200个案例样本允许对国家成年人口进行推断，抽样误差不超过±2.8%，置信水平为95%。在样本量为n=2,400的情况下，误差范围降低至±2.0%，置信水平为95%。

样本设计是一种集群、分层、多阶段、区域概率样本。具体而言，我们首先根据主要次国家政府单位（州、省、地区等）以及城市或乡村位置对样本进行分层。区域分层减少了独特的族群或语言群体被排除在样本之外的几率。Afrobarometer偶尔会故意对国家内部政治上具有显著性的某些群体进行过度抽样，以确保子样本的大小足以进行分析。任何过度抽样将在技术信息报告中注明。

样本阶段
样本的抽取分为四或五个阶段：
阶段1：仅在乡村地区，第一阶段是抽取次级抽样单元（SSU）。SSU在城市地区不使用，在某些国家农村地区也不使用。有关任何给定国家的具体样本细节，请参阅伴随每个数据集的技术信息报告。
阶段2：随机选择一级抽样单元（PSU）；
阶段3：然后随机选择抽样起点；
阶段4：访谈员随后随机选择家庭；
阶段5：在家庭内部，访谈员随机选择受访者。每位访谈员在每个家庭中交替采访男性和女性受访者，以确保样本性别平衡。为了将现场工作的成本和物流控制在可管理的范围内，每个选定的PSU内部聚集了八个访谈。
