Census-Block-Group-Level-2020-Presidential-Election-Results (Updated Sep 2021)

A dataset ('data/out/precinct_cbgs_all_2020.csv.gz') with estimates of Census Block Group level 2020 presidential election results, and the underlying data and code that generated it.

Derived from the dataset compiled by the New York Times and the Census Block Group shapefiles from the Census Bureau. All non-voting variables are defined and named as in those shapefiles. All voting variables are defined and named as in the NYT geojson. For a description of the matching algorithm, see Van Dijcke and Wright (2021). Credit to Maria Milosh for coding help.

⚠️⚠️⚠️ Important note: ⚠️⚠️⚠️ the current NYT dataset is incomplete. We only include states that either have full precinct coverage, or where precinct-level results are missing entirely for certain counties -- as in that case, they will be missing entirely for the CBGs within those counties, and so there won't be missing CBGs within the precincts. Use with caution. For a list of state-specific data collection issues, see the NYT Git repository. The states currently included are: AZ, AR, CA, CO, DE, DC, FL, GA, HI, ID, IA, IL, ID, KS, LA, MD, MA, MI, MN, MS,MT ,NE, NV, NM, NY, NC, ND, OH, OK, OR, PA, SC, SD, TN, TX, UT, VA, WA, WV, WI, WY ~ .
