Summary: The number of registered voters as of September 2020 and the turnout rate in the 2018 presidential election by immigration status and race. The turnout rate reflects the percentage of currently registered voters in each geography (as of September 2020) that voted in the 2018 presidential election, regardless of whether they were living in the same place in 2018 or were eligible to vote.
Data Source(s): Political Data, Inc., politicaldata.com.
Universe: All U.S. citizens registered to vote as of September 2020.
Methods: Political Data Inc. data files for each racial/ethnic and nativity group were downloaded from the PDI website for the 2008, 2010, 2012, 2014, 2016, and 2018 general elections at the state, county and city/place levels. Data was aggregated by nativity and geography type. All excess data from place files was removed so that only city level data was used. Total votes by year were then divided by total currently registered voters as of September 2020 to derive a measure of total votes as a share of currently registered voters. Data for geographies and demographic groups was set to missing if based on fewer than 30 registered voters or if less than 75 percent of all registered voters for a racial/ethnic group had valid nativity information within a given geography. See the methodology page for other relevant notes.
- Racial/ethnic identification of data on registration and voting is only available for the following groups: Italian, Russian, Armenian, Iranian, Arab, Black, Portuguese, Latino, Indian, Other Southeast Asian, Vietnamese, Filipino, Chinese, Japanese, Korean, Pacific Islander. It is imputed based on surnames and data fields.
- Nativity information is based on the listed countries of origin on voter registration forms and is sometimes missing.
- Data by nativity is based on registered voters for which nativity information is available, while data for all voters (immigrant and U.S. born combined) is based on all registered voters.
- No data is reported if based on fewer than 30 registered voters or if nativity information is reported for less than 75 percent of all registered voters as of September 2020.
