Socioeconomic disadvantage is a major correlate of low political participation. This association is among the most robust findings in political science. However, it is based largely on observational data. The causal effects of early-life disadvantage in particular are even less understood, because long-term data on the political consequences of randomized early-life anti-poverty interventions is nearly nonexistent. We leverage the Moving to Opportunity (MTO) experiment to test the long-term effect of moving out of disadvantaged neighborhoods—and thus out of deep poverty—on turnout. MTO is one of the most ambitious anti-poverty experiments ever implemented in the United States. Although MTO ameliorated children’s poverty long term, we find that, contrary to expectations, the intervention did not increase children’s likelihood of voting later in life. Additional tests show the program did not ameliorate their poverty enough to affect turnout. These findings speak to the complex relationship between neighborhood disadvantage and low political participation.

We present novel evidence that attitudes toward nonpartisan social groups structure political belief systems. First, we show that most Americans have a rich knowledge of the social groups that support and oppose group-related policies. This knowledge often exceeds people’s awareness of where Democrats and Republicans stand on these same issues. Then, we show that this knowledge promotes what Philip Converse called ideological coherence: Americans who know which groups support and oppose a policy are more likely to hold stable policy positions over time and to organize their attitudes into consistently liberal or conservative bundles. In the twentieth century, knowledge of social groups’ issue positions rivaled knowledge of parties’ positions in its ability to generate attitude stability and constraint. However, as party identification has strengthened in recent decades, knowledge of parties’ positions has become the most important source of structure in most Americans’ belief systems.

Low rates of youth voting are a feature of contemporary democracies the world over, with the United States having some of the lowest youth turnout rates in the world. However, far too little is known about how to address the dismal rates of youth voter participation found in many advanced democracies. In this paper, we examine the causal effect of a potentially scalable solution that has attracted renewed interest today: voluntary national service programs targeted at the youth civilian population. Leveraging the large pool of young people who apply each year to participate in the Teach For America (TFA) program—a prominent voluntary national service organization in the United States that integrates college graduates into teaching roles in low-income communities for 2 y—we examine the effect of service participation on voter turnout. To do so, we match TFA administrative records to large-scale nationwide voter files and employ a fuzzy regression discontinuity design around the recommended admittance cutoff for the TFA program. We find that serving as a teacher in the Teach For America national service program has a large effect on civic participation—substantially increasing voter turnout rates among applicants admitted to the program. This effect is noticeably larger than that of previous efforts to increase youth turnout. Our results suggest that civilian national service programs targeted at young people have great promise in helping to narrow the stubborn and enduring political engagement gap between younger and older citizens.

The 2020 presidential election brought expanded vote-by-mail opportunities, a rise in attacks on this process’s integrity, and the implementation of novel programs such as California’s Where’s My Ballot? system to ensure confidence in mail balloting. Can heightening awareness of this ballot-tracking system and other election protections alleviate fraud concerns and raise turnout? We assess whether messages reinforcing election integrity increased participation in the 2020 election through a large-scale voter mobilization field experiment. California registrants were mailed a letter that described either existing safeguards to prevent vote-by-mail fraud or the ability to track one’s ballot and ensure that it was counted. Analysis of state voter records reveals that neither message increased turnout over a simple election reminder or even no contact, even among subgroups where larger effects might be expected. In the context of a high-profile, high-turnout presidential election, assurances about ballot and electoral integrity did not increase turnout.
