The 1915 Iowa State Census Project

The 1915 Iowa State Census is a unique document. It was the first census in the United States to include information on education and income prior to the United States Federal Census of 1940. It contains considerable detail on other aspects of individuals and households, e.g., religion, wealth and years in the United States and Iowa. The Iowa State Census of 1915 was a complete sample of the residents of the state and the returns were written by census takers (assessors) on index cards. These cards were kept in the Iowa State Archives in Des Moines and were microfilmed in 1986 by the Genealogical Society of Salt Lake City. The census cards were sorted by county, although large cities (those having more than 25,000 residents) were grouped separately. Within each county or large city, records were alphabetized by last name and within last name by first name. This data set includes individual-level records for three of the largest Iowa cities (Des Moines, Dubuque, and Davenport; the Sioux City films were unreadable) and for ten counties that did not contain a large city. (Additional details on sample selection are available in the documentation). Variables include name, age, place of residence, earnings, education, birthplace, religion, marital status, race, occupation, military service, among others. Data on familial ties between records are also included.

The 1974-1979-1980 Canadian National Elections and Quebec Referendum Panel Study

This study is a continuation of the 1974 Canadian Election Study, which consisted of extensive personal interviews with a national sample of 2,562 respondents following the federal election of July 8, 1974. Immediately following the federal election of May 22, 1979, 1,295 of the original respondents were successfully contacted and interviewed, thereby creating a 1974-1979 panel study. In addition, a new national sample of the l979 electorate and a supplementary sample of young voters (aged 18-23) were drawn and personal interviews utilizing the same questionnaire were conducted with respondents in these samples. After the federal election of February 18, 1980, 1,748 respondents in both the panel and cross-section samples were contacted by telephone and reinterviewed. No new respondents were added to the 1980 sample. When the Quebec referendum was called for May 20, 1980, a decision was made to contact by telephone Quebec respondents originally sampled in l974 or 1979 and interviewed in 1980. Of these respondents, 325 were successfully contacted and reinterviewed. Approximately half of the interviews were conducted immediately prior to the referendum, and the remaining half immediately afterward. The 1974 post-election survey covered a wide range of topics related to citizen participation in politics. The 1979 survey continued the theme of citizen interest and involvement in politics and probed respondents' attitudes about regions, provinces, and national unity. The 1980 telephone interview asked about vote choice in 1980, party identification, and the issue of energy. Questions on the Quebec referendum centered around the respondents' views on constitutional options for Quebec.

1980 and 1990 Industrial Structure Measures

The major objective of this research project was to analyze differences among race-sex groups in their distribution across industrial and occupational segments and in the rewards that they receive from these positions. Two sets of analyses of the causes and results of the differential distribution among Black women, Black men, white women, and white men are provided, and the redistribution of these groups across labor market positions is also examined.

1988/1989 Maricopa Household Travel Study

AAU Campus Climate Survey on Sexual Assault and Sexual Misconduct

In 2015, the American Association of Universities (AAU) and member institutions designed and implemented the first Campus Climate Survey. This survey aimed to assess the prevalence of sexual assault and sexual misconduct in American universities, as well as how the campus climate may be related to or contribute to misconduct. One of AAU’s goals in designing this survey was to provide academic institutions with the information they need to create or modify policies that address the problem of sexual misconduct on campus. The survey was implemented again in 2019.   The Campus Climate Survey is considered the largest survey of its kind, with over 150,000 students from 27 colleges and universities completing the 2015 survey, and over 180,000 students from 33 colleges and universities completing the 2019 survey. It includes a mix of undergraduate and graduate and professional school respondents, as well as respondents from both public and private institutions.   Additional Resources from AAU: Report on the AAU Campus Climate Survey on Sexual Assault and Misconduct (January 17, 2020) Press Release: AAU Releases 2019 Survey on Sexual Assault and Misconduct (October 15, 2019) Methodology Report for the AAU Campus Climate Survey on Sexual Assault and Sexual Misconduct (April 12, 2016) Press Release:  AAU Releases Campus Climate Survey on Sexual Assault and Sexual Misconduct (September 21, 2015)

ABC News/Washington Post Poll Series

Investigator(s): ABC News/Washington Post Since 1981, ABC News and The Washington Post, both separately and together, have commissioned public opinion polls to collect information on the American public's attitudes and opinions on various issues. These surveys, conducted by Chilton Research Services until mid-1999 and subsequently by Taylor Nelson Sofres Intersearch, gather information in the form of monthly and special topic polls. Monthly polls solicit respondent information on the presidency and on a variety of other political and social issues. Special topic polls focus on specific events or issues that are of timely significance.

AP VoteCast Series

AP VoteCast is a survey of the American electorate conducted by NORC at the University of Chicago for The Associated Press and Fox News. Developed by The Associated Press and NORC at the University of Chicago, AP VoteCast is a new way to survey voters. The Associated Press and Fox News, among other news outlets, use the data to explain election outcomes and the mood of the electorate in their election night coverage. VoteCast debuted for the 2018 midterm elections after years of testing and development and was used again for the 2020 Democratic primaries, 2020 presidential election, 2020 special Senate elections in Georgia, 2021 gubernatorial election in Virginia, and 2022 midterm elections. In 2024, it covered the presidential primaries and caucuses and will be covering the presidential election in November. VoteCast was designed by NORC at the University of Chicago and The Associated Press to provide a new approach to understanding elections. Using a random, probability-based sample of registered voters to carefully calibrate a very large sample from opt-in, online panels, VoteCast delivers the best of both methods – the accuracy of probability-based surveys combined with the scale provided by an opt-in survey that interviews tens of thousands of people quickly. Because VoteCast is not based on in-person interviews at the polling booth, the adaptive methodology meets voters where they are and accurately captures voter sentiment no matter how people choose to vote. It provides results in every state holding a statewide election, which means VoteCast delivers a broader portrait of the American electorate than any other election survey. The Associated Press and NORC are committed to transparency of VoteCast’s methods and results, as well as continual improvement of the VoteCast methodology.
