The Cooperative Congressional Election Study (CCES) studies how Americans view Congress and hold their representatives accountable during elections, how they voted and their electoral experiences, and how their behavior and experiences vary with political geography and social context. This study constructed a very large sample capable of capturing variation across a wide variety of legislative constituencies. The state-level samples are sufficiently large as to measure with a reasonable degree of precision the distribution of voters' preferences within most states. The 2010 CCES involved 30 teams, yielding a Common Content sample of 55,400 cases. The Latino-Hispanic Survey was conducted concurrent to the core CCES study. The Latino-Hispanic Survey was a study of Latino/Hispanic individuals, yielding 1,150 voting-age Latinos. As part of the study, the core set of 2010 CCES Common Content questions were asked along with a battery of Latino-specific questions. Demographic information include age, income, race, and gender.
