Abstract: |
This dataverse includes crosswalks between 2020 Census block geography and older Census geography, as well as certain data fields reaggregated to the 2020 blocks and rounded to whole numbers. The Census provides crosswalks between 2010 and 2020 block geography (https://www.census.gov/geographies/reference-files/time-series/geo/relationship-files.html), but the only measure that is given of what share of a 2010 block belongs to a 2020 block in the case of a split is area. Broadly speaking, the files on this dataverse were made using the method outlined in our (Brian Amos and Michael McDonald) 2017 paper in Public Opinion Quarterly entitled "When Boundaries Collide: Constructing a National Database of Demographic and Voting Statistics," where the National Land Cover Database is used to better predict where people live in the case of a split block. See readme.txt for more details, as well as licensing and warranty information. |
