2016 Latino Immigrant National Election Study (LINES), [United States] (ICPSR 38129)
The 2016 Latino Immigrant National Election Study (LINES) is a panel study of Latino foreign-born residents of the United States, with telephone surveys of nationally representative samples of respondents fielded in 3 waves over 2016-2017.
The first survey in the 2016 LINES took place during the general election campaign (August and September of 2016). Interviews (N = 1,800) were conducted in English and Spanish, although nearly all respondents opted for Spanish. Because many of the initial telephone numbers dialed were either out of service or otherwise unusable, the American Association for Public Opinion Research (AAPOR) "Response Rate 1" calculation is low (.034). However, in cases when an eligible immigrant was identified based on the initial screening questions, only 12 percent opted not to complete the survey. On average, an interview that fall lasted approximately 25 minutes.
After the 2016 election, 576 immigrants took part in the second survey wave, which was fielded during the presidential transition period (a 32 percent re-contact rate). At this time, an additional fresh sample of 260 Latino immigrants was added to the study, again to help gauge and ameliorate any potential respondent attrition biases. Finally, in the summer of 2017 (July through early-September), a third wave was conducted, with all 1,800 immigrants from the pre-election baseline survey being eligible for interviewing. In this period, 31 percent of these immigrants (N = 554) were surveyed; this included 321 respondents who had taken part in the second wave and 233 who had not. To increase the sample size at this time and address attrition over time, 500 fresh immigrants were surveyed. In total, 2,560 immigrants took part in the 2016-2017 LINES: 1,800 from before the election, 260 during the presidential transition period, and 300 in the summer of 2017.
The questionnaire instrumentation used in the study was largely adapted from item wordings in the 2012 American National Election Study (ANES). The survey focuses on immigrant civic engagement and political socialization, including items on immigrant attitudes, opinions and electoral and non-electoral political behavior.

Study ICPSR 00013 contains county-level returns for all elections to the same national and state offices, plus one additional state-wide office, usually attorney general or secretary of state.
This data collection provides summary information about candidates contesting elections and special elections anywhere in the nation, political party name and ICPSR party ID code, and the number of votes received by each candidate in the constituency for elections between 1788 and 1990. The information also include election for which returns are available solely at the constituency level and not found in the country-level files of elections returns described above. For detailed information about candidates and contests, please refer to study Constituency Statistics of Elections in the United States, 1788-1990 (ICPSR 7757).
This release further include 1990 data from the District of Columbia election for United States senator and United States representative.

Elections for these offices were postponed until the 1990 general election. The three offices are currently local District positions, which will turn into federal offices if the District becomes a state.

Community College Civic Outcomes Survey, Spring 2015 (ICPSR 36833)
The Community College Civic Outcomes Survey, Spring 2015 study examines the individual and institutional factors associated with greater civic agency, capacity, behavior, and knowledge among college students. In Spring 2015, two surveys were digitally administered at nine community colleges. These nine colleges were purposively selected for diversity in terms of geography, campus setting, size, and the racial and ethnic composition of their student bodies. From a total of 98,838 recipients, 4,788 usable surveys were returned, for an aggregate five percent response rate (response rates varied from two to 13% among the nine colleges). This data includes a sample of 3,897 from those surveys collected.
The Civic Outcomes Survey (COS) was administered to students, and included questions related to voting, political and community engagement, civic knowledge, and leadership development. The Institutional Questionnaire (IQ), was admitted to each college's liaisons to The Democracy Commitment (TDC), and included questions related to college-level factors known to influence student engagement. These questions assessed for institutional intentionality towards civic engagement through college missions and strategic planning, as well as academic and faculty focus on civic involvement. Both instruments were previously tested in a small regional pilot and were subsequently refined to allow for greater response variability. Demographic variables include race, income, gender, and enrollment status.

Detroit Area Study, 1957: Leader Survey (ICPSR 7107)
This study investigated political activities and attitudes of 77 Republican and 72 Democratic precinct leaders in Wayne County, Michigan. The interviews focused on county-, district-, and precinct-level organization and activities as well as on related perceptions, attitudes, and behaviors of the party leadership toward the party structure at each level. Questions probed the respondents' living experiences before coming to Detroit, and their behavior regarding changes of residence since coming to Detroit. The use of phones within the home was also ascertained. Items assessing various influences on the respondents' political attitudes and behaviors were included in the interview. The respondents were asked to indicate the mass media on which they depended most heavily for political information, and how often politics was discussed in meetings with family, friends, neighbors, and other groups to which they belonged. The strength of the respondent's political party affiliation and perceptions of differences between the major parties on various issues were also explored. Questions were asked about the importance and frequency of voting, the respondent's knowledge of and involvement in local party politics, knowledge of precinct workers and the state party chairman, and general attitudes toward politics and political figures such as Adlai Stevenson and Dwight Eisenhower. Also studied were the respondent's opinions regarding several controversial issues, including national health care, school integration, ending the selective service system, and monetary aid to countries that were not anti-communist. Background variables established the respondent's age, sex, race, educational level, marital status, occupation, social class, political affiliation, number of children, religious preference, and relationship to the head of the household. Demographic information was also collected on the respondent's father.
