In CMAP-REPOS/cmapgeo: R-Friendly Geodata for the Chicago Region

cmapgeo 0.2.2

December 29, 2023

• All datasets based on the Census Bureau's TIGER/Line boundaries have been updated with the 2023 vintage, including the redistricted boundaries for both state and federal legislative districts (2020 vintage). Congressional districts rely on a manual update and should be reverted to use congressional_districts when that function can retrieve districts from the 118th Congress.
• All datasets based on CMAP's data hub have been migrated to the new ArcGIS Online data hub link and new file format.
• Crosswalks and shapefiles have been updated with latest vintages.

cmapgeo 0.2.1

February 13, 2023

• All datasets based on the Census Bureau's TIGER/Line boundaries have been updated with the 2022 vintage.
• Adds documentation note that the CMAP Data Hub is offline. All data derived from the Data Hub will remain for reference and will be updated with new links when the CMAP Data Hub is available once again.
• Shapefiles for 2010 Census products (blocks, tracts, and block groups) have been removed from the package to minimize file size. Crosswalks from 2010 geographies are still available for historical reference.

cmapgeo 0.2.0

February 23, 2022

• block_sf, blockgroup_sf and tract_sf now represent the 2020 census geographies. (2010 census geographies are still available with a _2010 suffix for use with ACS data from 2010 through 2019.)
• Crosswalk tables (xwalk_*) have also been updated to use 2020 Census data, and a new employment allocation factor (based on 2019 LEHD data) has been added to each. The prior crosswalks based on the 2010 Census data are still available with a _2010 suffix for use with ACS data from 2010 through 2019 (although they still lack an employment allocation factor).
• All datasets based on the Census Bureau's TIGER/Line boundaries have been updated with the 2021 vintage. (The exception is the 2010 blocks, block groups and tracts, which are still based on the 2019 vintage.)
• Added sf and tibble packages as requirements instead of suggestions.

cmapgeo 0.1.3

November 3, 2021

• Added block_sf_2020, blockgroup_sf_2020 and tract_sf_2020 for use with data from the 2020 decennial census. (Note: once the Census Bureau publishes the 2016-2020 ACS 5-year data, these datasets will be renamed to replace block_sf, blockgroup_sf and tract_sf.)

cmapgeo 0.1.2

June 11, 2021

• Changed class of cca_sf and ward_sf from sf-tibble to sf-data.frame, for consistency with all other cmapgeo datasets.

cmapgeo 0.1.1

June 8, 2021

• Added Census ZIP Code Tabulation Areas (ZCTAs) as zcta_sf.

cmapgeo 0.1.0

May 26, 2021

• Initial package release. At this point, it is essentially just a repository of geodata and crosswalk tables.
