Collaborative Multi-racial Post-election Survey (CMPS), United States, 2016

web-based surveyETHNIC_QUOTA was a variable used in the data collection only, so that the data collection vendor could assign cases towards the quota targets of each racial group towards the counts. The Principal Investigators do not necessarily recommend using this variable for analysis, rather they recommend scholars use the self-reported race and ethnicity of respondents to create their own estimates for race. However, the ethnic quota variable can be used, but this variable assigns each respondent a primary race/ethnicity group, again, just for the purposes of the quota count.The restricted-use dataset contains geographical information which has been masked in the public-use dataset. The variables ZIPCODE and C342 contain zip codes, and CITY_NAME and C347_CITY contain the name of cities. The day-in-date for INTERVIEW_START, INTERVIEW_END, and TIME_304 has been recoded to the first of the month in the public-use dataset but is preserved in the restricted-use dataset.For additional information on the Collaborative Multi-racial Post-election Survey, please visit the CMPS website.This collection is related to the following studies: Collaborative Multi-racial Post-election Survey (CMPS), 2012, ICPSR 37132 Collaborative Multi-racial Post-election Survey (CMPS), 2008, ICPSR 35163

本次网络调查中，ETHNIC_QUOTA仅用于数据采集流程，用于协助数据采集供应商依据各种族群体的配额目标完成案例分配与计数。
本研究的首席研究员并不建议将该变量用于分析工作，而是推荐学者基于受访者自行上报的种族与族裔信息，自行构建种族相关的估算结果。
不过，研究者仍可使用该族裔配额变量——该变量仅为满足配额计数需求，会为每位受访者分配一个主要种族/族裔群体。
受限使用数据集包含地理信息，此类信息在公开使用数据集中已被掩码处理。
变量ZIPCODE与C342存储邮政编码信息，变量CITY_NAME与C347_CITY存储城市名称信息。
公开使用数据集中，INTERVIEW_START、INTERVIEW_END与TIME_304的日期细节已被重编码为当月1日，但受限使用数据集保留了原始完整日期信息。
