Study Design Highlights

Data collection for the ANES 2020 Time Series Study pre-election interviews began in August 2020 and continued until Election Day, Tuesday (November 3). Post-election interviews began soon after the election and continued through the end of December. This field period began earlier than the traditional ANES field period, which typically starts the day after Labor Day and concludes the day before Election Day.

The ANES 2020 Time Series Study features a fresh cross-sectional sample, with respondents randomly assigned to one of three sequential mode groups: web only, mixed web (i.e., web and phone), and mixed video (i.e., video, web, and phone). The study also features re-interviews with 2016 ANES respondents (conducted by web), and post-election surveys with respondents from the General Social Survey (GSS). Data from GSS participants have been separately released as part of the ANES-GSS 2020 Joint Study.

Weights Summary

Several weight variables are available, each intended to be used with particular study components or aggregations of cases. Weights should be used in analyses to accurately represent the population. For correct standard errors, users should employ procedures that take into account the complex sampling design.
