Census 2020 counts of counties, places, county subdivisions, townships by US state

by Charles Purvis

One of the more underutilized census geographies, in my opinion, are “county subdivisions”. I don’t think we ever tabulated and reported data for this particular geographic level in any of our work (at MTC, SF Bay Area MPO, my tenure there between 1981-2009). More recently, I’ve been messing around with historical census data, including county subdivisions, focusing on California and Alameda County. I live in what was formerly called “Eden Township” named after settlers who moved here from Mt Eden, Kentucky in the 1850s. The term “township” in California was used between the 1860 and 1950 Censuses, after which the Census Bureau switched to the “Census County Division” or “CCD” concept starting in 1960 in California and other states. (CCDs were first used in Washington State in the 1950 Census.) So, my thought was “how many townships remain in the United States?” A few months ago I started an R stat package analysis (tidycensus, dplyr) to find “places called Eden” and “places called Paradise” and “places called Cupcake”…… I extended this analysis to county subdivisions (COUSUB) and then subsetted county subdivisions with the word “township” in their name. Alas, there are no East Cupcakes in the United States! The resulting tally of counties, place, county subdivisions, and townships by US state is included in links to files on my GitHub. My r script to create this is shared, here: https://github.com/chuckpurvis/r_scripts/blob/main/pl94171_places_called_ed… https://github.com/chuckpurvis/r_scripts/blob/main/census2020_county_townsh… https://github.com/chuckpurvis/r_scripts/blob/main/census2020_county_townsh… 3,221 counties in the United States (including Puerto Rico and the District of Columbia) 36,678 county subdivisions in the United States (incl PR + DC) 17,701 townships in the United States (incl PR+ DC) 31,909 places in the United States (incl PR + DC) Most counties? Texas, with 254 counties. Most county subdivisions? Minnesota, with 2,761 county subdivisions (COUSUB) Most townships? Minnesota, with 1,802 townships. Most places? Pennsylvania with 1,888 places. How many states still have townships? Fifteen. Hope this is of interest. Chuck Purvis, Hayward, California Eden Township

New Census data releases for August - December 2023

by Charles Purvis

The next several months should keep census data analysts quite busy. https://www.census.gov/newsroom.html New decennial census (2020) products will include: Thursday, August 31, 2023: DHC file for 118th Congressional Districts; Current State houses. This will be the first Census 2020 data products using the new congressional district boundaries based on Census 2020, and as used in the November 2022 general election. This will include summary levels at the new state house and state senates for all states. Thursday, September 21, 2023: DHC-A file with the detailed race-ethnicity groups. https://www.census.gov/newsroom/press-releases/2023/2020-census-detailed-dh… New American Community Survey data products including 2022 data will include: Thursday, September 14, 2023: 1-year Data Release (2022) Thursday, October 19, 2023: 1-year Public Use Microdata Sample (2022) Thursday, December 7, 2023: 5-year Data Release(2018-2022) Thursday, January 25, 2024: 5-year Public Use Microdata Sample (2018-2022) https://www.census.gov/programs-surveys/acs/news/data-releases/2022/release… My guess is that these data will be readily accessible via data.census.gov <http://data.census.gov/> and the census bureau’s API structure. I will probably be using the tidycensus, tidyverse, ggplot2 R packages to retrieve, reduce, report, chart and map results. Hope this helps: Chuck Purvis retired person, Hayward California
