The American National Election Studies (ANES) has surveyed American citizens before and after every presidential election since 1948. The survey provides the public with a rigorous, non-partisan scientific basis for studying change over time in American politics.
The interactive graphs below illustrate the changing American electorate and some of the factors that may motivate voters’ choices at the ballot box. Mouse over the graphs for more detail.
Since its establishment in 2013, a total of 137 posts have appeared on the Center for Political Studies (CPS) Blog. As we approach the new year, we look back at 2017’s most-viewed posts. Listed below are the posts that you, our dear readers, found most interesting on the blog this year.
There are political issues and then there are moral political issues. Often cited examples of the latter include abortion and same sex marriage. But what makes a political issue moral?An extensive literature already asserts a moral vs. not moral issue distinction. Yet, there is no consensus in how to distinguish between moral and non-moral political issues. Further, trying to sort issues into these categories proves challenging.
By closely investigating all known cases of state-backed cross-sector surveillance collaborations, our findings demonstrate that the deployment of mass surveillance systems by states has been globally increasing throughout the last twenty years. More importantly, from 2006-2010 to present, states have uniformly doubled their surveillance investments compared with the previous decade.
In 2012, Barack Obama received 93% of the African American vote but just 39% of the White vote. This 55% disparity is bigger than vote gaps by education level (4%), gender (10%), age (16%), income (16%), and religion (28%). And this wasn’t about just the 2012 or 2008 elections, notable for the first appearance of a major ticket African American candidate, Barack Obama. Democratic candidates typically receive 85-95% of the Black vote in the United States. Why the near unanimity among Black voters?
Both parties moving toward ideological poles has resulted in policy gridlock (see: government shutdown, debt ceiling negotiations). But does this polarization extend to the public in general? To answer this question, Iyengar measured individual resentment with both explicit and implicit measures.
The enthusiasm for both Trump and Sanders’ messages about the influence of money in politics brings up an important question: Is policy driven by the rich, or does government respond to all? Political scientists have long been interested in identifying to what degree wealth drives policy, but not all agree on it’s impact.
Exploring the Tone of the 2016 Election by U-M undergraduate students Megan Bayagich, Laura Cohen, Lauren Farfel, Andrew Krowitz, Emily Kuchman, Sarah Lindenberg, Natalie Sochacki, and Hannah Suh, and their professor Stuart Soroka (2017)
Political economists often theorize about relationships between politics and macroeconomics in the developing world; specifically, which political or social structures promote economic growth, or wealth, or economic openness, and conversely, how those economic outcomes affect politics. Answering these questions often requires some reference to macroeconomic statistics. However, recent work has questioned these data’s accuracy and objectivity. An under-explored aspect of these data’s limitations is their instability over time.
In a recent piece in the Washington Post, we addressed some common misconceptions about what the Swedish crime data can and cannot tell us. However, questions about the data persist. These questions are varied but are related to two core issues: (1) what kind of data policy makers need to inform their decisions and (2) what claims can be supported by the existing data.
Ryan’s overarching hypothesis boils non-compromise down to morals: a moral mindset orients citizens to oppose political compromises and punish compromising politicians. There are all kinds of issues for which some citizens seem resistant to compromises: tax reform, same-sex marriage, collective bargaining, etc. But who is resistant? Ryan shows that part of the answer has to do with who sees these issues through a moral lens.
Ballots list all candidates officially running for a given office so that voters can easily choose between them. But could the ordering of candidate names on a ballot change some voters’ choices?
Since 1948, the ANES- a collaborative project between the University of Michigan and Stanford University- has conducted benchmark election surveys on voting, public opinion, and political participation. This year’s polarizing election warranted especially interesting responses.
The initial release of the 2016 American National Election Studies (ANES) Time Series dataset is approaching. Since 1948, the ANES- a collaborative project between the University of Michigan and Stanford University- has conducted benchmark election surveys on voting, public opinion, and political participation. This year’s polarizing election warranted especially interesting responses. Shanto Iyengar, one of the project’s principal investigators and Stanford professor of political science, noted, “The data will tell us the extent to which Trump and Clinton voters inhabit distinct psychological worlds.”
To learn more about the study, we asked Ted Brader (University of Michigan professor of political science and one of the project’s principal investigators) a few questions about this year’s anticipated release.
When was the data collected?
The study interviewed respondents in a pre-election survey between September 7 and November 7, 2016. Election day was November 8. The study re-interviewed as many as possible of the same respondents in a post-election survey between November 9 and January 8, 2017.
The ANES conducted face-to-face and internet interviews again for 2016. How are these samples different from 2012? What are the sample sizes and the response rates?
The study has two independently drawn probability samples that describe approximately the same population. The target population for the face-to-face mode was 222.6 million U.S. citizens age 18 or older living in the 48 contiguous states and the District of Columbia, and the target population for the Internet mode was 224.1 million U.S. citizens age 18 or older living in the 50 U.S. states or the District of Columbia. In both modes, the sampling frame was lists of residential addresses where mail is delivered, and to be eligible to participate, a respondent had to reside at the sampled address and be a U.S. citizen age 18 or older at the time of recruitment.
The response rate, using the American Association for Public Opinion Research (AAPOR) formula for the minimum response rate on the pre-election interview, was 50 percent for the face-to-face component and 44 percent for the Internet component. The response rate for the face-to-face component is weighted to account for subsampling during data collection; due to subsampling for the face-to-face mode, the unweighted response rate would not be meaningful.

The re-interview rate on the post-election survey was 90 percent for the face-to-face component and 84 percent for the Internet component.
Are there any other aspects of the design that you think are particularly important?
I’d emphasize the effort to collect high quality samples via both in-person and online interviews for the whole survey as obviously the most important design aspect of the 2016 study, helping us to learn more about the trade-offs between survey mode and potential benefits of mixed mode data collection.
Are there any new questions that you think users will be particularly interested in?
Along with many previous questions that allow researchers to look at short and long term trends, we have lots of new items related to trade, outsourcing, immigration, policing, political correctness, LGBT issues, gender issues, social mobility, economic inequality, campaign finance, and international affairs.
What do you think some of the biggest challenges were for the 2016 data collection?
With increasing levels of polarization and a highly negative campaign, some Americans were much more resistant to participating in the survey. Many seemed to feel alienated, distrustful, and sick of the election. Under these circumstances, we worked hard with our partners at Westat to overcome this reluctance and are pleased to have recruited such a high quality sample by Election Day.
What are you most excited about when you think of the 2016 ANES?
The 2016 contest was in many ways a particularly fascinating election, even for those of us who usually find elections interesting! The election ultimately centered on two highly polarizing candidates, and people of many different backgrounds felt a lot was at stake in the outcome. Thus, not surprisingly, there was energetic speculation throughout the year about what voters were thinking and why they supported Clinton or Trump. The 2016 ANES survey provides an incredibly rich and unparalleled set of data for examining and testing among these speculations. I expect it will take some time to arrive at definitive answers, but I’m excited to release this wealth of evidence so the search for the truth can begin in earnest.
Is there anything else you’d like to share?
I would note that future releases will include redacted open-ended comments by respondents, numerical codings of some of the open-ended answers, and administrative data (e.g., interviewer observations, timing, etc.).
As of October, the latest national polls, predicted that the 2016 Election results will reflect the largest gender gap in vote choice in modern U.S. history. Today, according to NPR, “An average of three recent national polls shows that women prefer Clinton by roughly 13 points, while men prefer Trump by 12, totaling a 25-point gap.” If these polls prove true, the 2016 results would indicate a much larger gender gap than what was observed in 2012, where women overwhelmingly supported Barack Obama over Mitt Romney.

University of Texas at Austin Professor Tasha Philpot argues that what really may be driving this gap to even greater depths, is race. For instance, here’s the same data from the 2012 Election, broken down by gender and race.

Often overlooked in the discussion of the gender gap, race figures prominently into many American’s political identities.

Philpot recently participated in the panel “What We Know So Far About the 2016 Elections” at the University of Michigan’s Center for Political Studies. In her talk, “Race and the Gender Gap in the 2016 Election,” Philpot outlined the potential sources for the gender gap and emphasized the role that race is playing in widening the gap.
Using data from the ANES 2016 Pilot Study, Philpot compared opinions from white and black men and women on several issues such as government spending, inequality and discrimination, and evaluations of the economy. While there were noticeable differences strictly between men and women, the real story became clear when Philpot sorted the results by gender and race. Small gender gaps exist among both whites and blacks, but the most remarkable difference of opinions on all issues is between black women and white men.

Evaluations of the Economy

On most issues, black women and white men fall on opposite sides of the political spectrum. Philpot concludes that it’s an oversimplification to consider the gender gap as merely a gap between men and women, when, in reality, the observed gender gap is largest between white men and black women.
What We Know So Far About the 2016 Elections, was held on October 5, 2016 at the Center for Political Studies, University of Michigan. The panel also included the following talks:

ICYMI (In Case You Missed It) this post details the Election Research Preacceptance Competition, organized by Arthur Lupia and Brendan Nyhan. Lupia discussed this initiative at the “Roundtable on the CPS Special Issue on Transparency in the Social Sciences” at APSA 2016 on Friday, September 2, 2016.
How can scholars study politics most effectively? The Election Research Preacceptance Competition (http://www.erpc2016.com) is an innovative initiative that will test a new approach to conducting and publishing political science research during the 2016 election.
Entrants in the competition will preregister a research design intended to study an important aspect of the 2016 general election using data collected by the American National Election Studies (ANES). A condition of entering the competition is that entrants must complete and register a design before the ANES data are released. Many leading academic journals have agreed to review scholarly articles that include these research plans and to review them before the data are available or results are known.
This is the last in a series of posts celebrating the 65th anniversary of the American National Election Studies (ANES). The posts have sought to highlight some of the many ways in which the ANES has benefited scholarship, the public, and the advancement of science.
As part of the 65th anniversary of the American National Election Studies (ANES), the ANES team created an interactive timeline. The timeline charts the history of the project with annotated notable dates and historic photographs. Here, we highlight three of the many entries.
The timeline begins with the inception of ANES. In 1948, social psychologists Angus Campbell and Robert Kahn and the University of Michigan’s Survey Research Center (SRC) surveyed the national electorate. The 1948 survey served as a pilot study for, and many consider to be the first implementation of, the ANES.
1964 – The Feeling Thermometer
The 1964 wave of the study pioneered the feeling thermometer. This unique question format asks respondents to gauge their feelings on a scale from “cold” to “warm”. Feeling thermometers have since been included in all ANES waves, with their use spreading globally and to all academic fields
1996 – Comparative Study of Electoral Systems
The independent Comparative Study of Electoral Systems (CSES) project coordinates the inclusion of common sets of questions in post-election surveys around the world. ANES first incorporated CSES questions in its 1996 wave, moving from national barometer to global participant in the process.
Please consider further exploring the interactive timeline to be reminded of some of the many significant moments throughout the history of this important scientific resource. And if you have ideas for additions to the ANES timeline, the study team would welcome your suggestions by email to: [email protected]
