Election Results
Extended Election Results
Extended elections results files are “endogenous” state legislative or
congressional results joined to precinct boundaries. These data are
critical for litigation and Voting Rights Act analysis. We’re calling
these datasets, which contain results from congressional and state
legislative contests “Extended.” These datasets may also contain
additional statewide results that aren’t included in existing files,
such as referenda, ballot questions, and other statewide races.
Disaggregated Election Results
Disaggregated election results down to the 2020 block level. Election
results are often released at the precinct level, which is not easily
joined with demographic data released on census geographies.
Block-level election data can enable easy aggregation to higher levels
of geography, such as counties or legislative districts, and joining
with demographic data, such as decennial census data.
Redistricting Data Joining
One of the most common tasks required for redistricting is the joining
of various datasets, especially demographic and election data. Because
redistricting data is available at so many levels of geography – and
geographies may change over time – this can be a difficult and time
consuming process. The Redistricting Data Hub can assist with tabular
and geospatial joins, using data from our website, and data you
provide.
Community of Interest Maps
The
Community of Interest COI Map Collection Project
aims to collect COI maps submitted to legislative and congressional
redistricting bodies and organizations during the 2021 redistricting
cycle. The database is in progress, you can download available data
through this project’s
Dataverse
and request in progress maps.
Local Boundaries and District Maps
We have compiled several
local redistricting resources, including local government websites containing redistricting data
or information for a particular city or county. Based on our
experience collecting local data, we have also drafted up guidance to
help you
collect key local redistricting datasets.
Racially Polarized Voting Datasets
Racially polarized voting
analysis often requires datasets which include both election results
and demographic data at the precinct level. If you do not see a
dataset on our site which currently fulfills your RPV requirements,
please let us know and we can make these datasets on request.
