Current Population Survey, September 2017: Volunteering and Civic Life Supplement

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey on the topic of volunteer service, which was administered as a supplement to the September CPS questionnaire. The Corporation for National and Community Service jointly sponsored the supplemental questions for September.
The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.
All persons eligible for the labor force items of the basic CPS were also eligible for the volunteer supplement. Altogether, 147,268 interviews were conducted during the period of September 10-19, 2017. Proxy responses were allowed if attempts for a self-response were unsuccessful. The supplement contained questions about the household member's participation in volunteer service from September 1, 2016, to the date of the interview. Household members were queried about the frequency of volunteer activity, the kinds of organizations they volunteered with, the types of activities they chose, whether any volunteering was done in a foreign country, and involvement in their community.
Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

本数据集包含两份调查问卷的应答数据：一是基础版当前人口调查（Current Population Survey，CPS），二是以2017年9月CPS问卷为蓝本增设的志愿服务主题补充调查。美国国家与社区服务公司（Corporation for National and Community Service）为本次9月补充调查的问卷内容提供联合赞助。
CPS为月度开展的劳动力调查，旨在提供美国人口经济状况与就业活动的即时估算数据。具体而言，该调查可估算全美总就业人数（含农业与非农业就业）、非农业自营劳动者、家政从业人员及非农业家庭企业中的无酬帮手、工资薪金雇员规模，同时可测算总失业人数。CPS数据采集的是调查前一周的相关信息。
所有符合基础CPS劳动力相关条目应答资格的受访者，同样具备参与本次志愿服务补充调查的资格。本次调查在2017年9月10日至19日期间共完成147268份访谈。若受访者无法自行完成应答，可由他人代为作答。补充调查的问题涵盖受访家庭成员在2016年9月1日至访谈当日期间的志愿服务参与情况，具体包括志愿服务频率、参与的志愿服务组织类型、所从事的志愿活动类别、是否在境外开展志愿服务，以及社区参与度等内容。
本次调查包含的人口统计学变量包括年龄、性别、种族、西班牙裔血统、婚姻状况、退伍军人身份、受教育程度、职业以及收入水平。
