Introduction

The Washington State Election Database housed at the Center for the Study of Demography and Ecology at the University of Washington offers a publicly available data set on estimated racial demographics in electoral precincts in Washington State. The data set covers all precincts from 2007 to 2022. We also provide an additional data set on language minority groups by each county in Washington State.

The project was funded by WA State Senate Bill 5597.

The tabs in this site provide links to downloadable tables, a map interface showing precint-level estimates of race proportions, and technical documentation, including the code that was used to generate the data and the web site itself.
