Afrobarometer (Rounds 2–9, country-level aggregates)非洲晴雨表（第 2–9 轮，国家层面聚合）

Afrobarometer is a pan-African, non-partisan survey research network that has measured public attitudes on democracy, governance, the economy and society since 1999. This dataset aggregates the merged Round 2 to Round 9 respondent files to the country level: one row is one country in one survey year, and each indicator is the weighted share of respondents giving a particular answer, using Afrobarometer's within-country weights.

Six core items that are asked in comparable form across rounds are hosted: support for democracy, satisfaction with the way democracy works, whether the country is seen as a democracy, trust in the president and in parliament, and perceived corruption in the presidency. Don't-know and refused answers are excluded from the base; the column n reports the number of valid respondents behind the support-for-democracy figure. Round 2 did not ask the 'extent of democracy' question, so that cell is empty.

Round 1 is delivered as a raw file but is not aggregated here: the merged Round 1 file contains no interview-date variable, so fieldwork years cannot be established from the data itself, and its response scales differ from later rounds. The respondent-level files for all nine rounds are included in the delivery.

非洲晴雨表（Afrobarometer）是覆盖全非洲的无党派调查研究网络，自 1999 年起持续测量公众对民主、治理、经济与社会的态度。本数据集把第 2 至第 9 轮的合并受访者文件聚合到国家层面：一行 = 一个国家在某一调查年，每个指标是使用 Afrobarometer 国内权重计算的加权作答比例。

此处托管各轮口径可比的 6 个核心题目：支持民主、对民主运行的满意度、认为本国是民主国家、对总统与议会的信任、以及对总统府腐败的感知。不知道/拒答不计入分母；`n` 列是"支持民主"一题的有效样本量。第 2 轮未问"民主程度"题，该格留空。

第 1 轮的原始文件随交付保留，但未纳入聚合：R1 合并档没有访问日期变量，无法从数据本身确定各国实地年份，且其量表与后续轮次不一致。九轮受访者级原始文件均已随交付附上。
