Policy Ideology Estimates for Canadian Electoral Districts, Municipalities, and 2019 Canadian Election Study Respondents

This repository contains ideology estimates from 2019 Canadian Election Study data for all federal electoral districts, all 2019 CES respondents, and the 250 largest municipalities in Canada. For more detail on our data and measurement approach, see Jack Lucas and David A. Armstrong II, "Policy Ideology and Local Ideological Representation in Canada," Canadian Journal of Political Science. 1. csd_out.dta and fed_out.dta. These are the aggregate ideology estimates for municipalities (csd_out) and federal electoral districts (fed_out). We provide census identifier codes and names, along with the estimated ideology score (median) and 95% probability intervals (lower, upper). 2. individual.dta. This file is for researchers who wish to use our estimates in individual-level analysis. The file includes the CES response ID variable, allowing for a simple merge back in to the main 2019 Canadian Election Study dataset. We provide the mean and standard deviation of each individual's ideology (idmean, idsd) along with 95% probability intervals (idupper, idlower).

本仓库基于2019年加拿大选举研究（Canadian Election Study, CES）数据集，生成并收录了针对所有联邦选举选区、全部2019年CES受访对象，以及加拿大250个最大自治市的意识形态估计结果。若需了解本数据集与测量方法的更多细节，请参阅Jack Lucas与David A. Armstrong II发表于《Canadian Journal of Political Science》的论文《Policy Ideology and Local Ideological Representation in Canada》。
1. csd_out.dta 与 fed_out.dta：二者分别为针对自治市（csd_out）与联邦选举选区（fed_out）的汇总意识形态估计结果文件。文件中包含普查识别编码与名称，以及估算得到的意识形态得分（中位数）与95%概率区间（下限、上限）。
2. individual.dta：该文件面向希望将本估计结果用于个体层面分析的研究人员。文件包含CES受访者ID变量，可直接与原始2019年加拿大选举研究主数据集进行合并。文件中提供了每位受访者意识形态得分的均值与标准差（idmean、idsd），以及对应的95%概率区间（idupper、idlower）。
