Current Population Survey, September 2014: Volunteer 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, 152,485 interviews were conducted during the period of September 14-23, 2014. 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, 2013, 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.

本数据集包含两套调查问卷的回复数据，分别为基础版《当前人口调查》（Current Population Survey，CPS）以及作为2014年9月CPS问卷补充模块的志愿服务主题调查。该补充问卷由美国国家与社区服务公司（Corporation for National and Community Service）联合赞助。

CPS为月度实施的劳动力调查，旨在提供美国人口经济状况与活动的当期估算数据。具体而言，其可估算总就业人数（含农业与非农业就业）、非农业个体经营者、家政工人及非农业家庭企业中的无酬协助者、工资薪金雇员人数，同时可提供总失业人数的估算值。CPS采集的数据为调查前一周的相关信息。

所有符合基础CPS劳动力项目参与资格的受访者，均具备参与本次志愿服务补充调查的资格。本次调查于2014年9月14日至23日期间开展，共计完成152485份访谈。若尝试获取受访者自行提交的回复未果，则允许使用代理回复。补充问卷涵盖受访者在2013年9月1日至访谈当日期间的志愿服务参与情况相关问题，具体包括志愿服务频率、参与的组织类型、参与的活动类别、是否在境外开展志愿服务，以及社区参与度相关内容。

本次数据集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、职业与收入水平。
