Post-Redistricting Geographies Now Available in Geocorr 2022

Geocorr 2022 just got better!

Many of our users have been asking when the new, post-Census-2020 Congressional districts would be available in Geocorr. The short answer is that 118th CDs are now included in Geocorr 2022, along with current state legislative districts.

A somewhat longer answer is that the U.S. Census Bureau has not yet released shapefiles or block lists for building 118th CDs or current SLDLs or SLDUs from 2020 tabulation blocks — and is not planning to do so for several months yet.

The Bureau’s Redistricting Data Office (RDO) intends to publish block equivalency files for the 118th Congress and for the 2022 state legislative districts, but not until December of 2022 at the earliest. And, the Bureau’s Geography division will not be releasing block allocation files for the same areas at all. However, the new areas will be published as shapefiles in the cartographic boundary files collection around April or May of 2023. They may also be released with the 2022 TIGER/Line shapefiles, generally around October.

Because of this lack of availability, we obtained new CD and state legislative boundary shapefiles from The American Redistricting Project, merged them, and ran intersections against 2020 TIGER/Line block shapefiles to determine how every block fits into the new districts. This was a tedious process, especially since the block and district shapefiles didn’t line up exactly, but we now have enough data to use for correlations.

With all that said, the new legislative geographies in Geocorr 2022 should be considered provisional until such time as they can be verified via official Census Bureau block equivalency files or shapefiles.

Of lesser interest (mainly for our Missouri users), Geocorr 2022 now also includes the most recent MO library districts.

Data Updates (June 2022)

We have a handful of data updates to report this spring.

In addition, for the convenience of our GIS users, we’ve added national shapefiles for the 2022-vintage congressional districts (118th Congress) and state upper- and lower-chamber legislative districts. These were compiled from individual state shapefiles downloaded from the American Redistricting Project. We have attempted to clean and normalize the attribute tables. Please note that these are not official Census Bureau shapefiles.

Please contact the MCDC website manager with any questions or comments.

Minor Data Updates (January 2022)

We have just a few minor data updates this month.

Please contact the MCDC website manager with any questions or comments.

ACS 2016-2020 five-year data release is delayed until March 2022

The U.S. Census Bureau announced on Nov. 10 that the American Community Survey (ACS) 2016-2020 five-year data release will be delayed until March 2022. The ACS normally releases its five-year data products in December of every year. However, according to the Bureau’s statement, “Additional time is needed to continue refining our methodology so that we can minimize the impact of nonresponse bias due to the COVID-19 pandemic.”

This delay will affect several of MCDC’s data applications, notably ACS Profiles, Circular Area Profiles (CAPS ACS), and Missouri County Fact Sheets.

Expect additional updates regarding this matter in December.

 

Data Updates (September 2021)

Just a couple of late updates this time. They’re late because the raw data was released later than usual due to COVID and the decennial census.

  • NCHS (National Center for Health Statistics) “bridged race” estimates for 2020, including state- and county-level numbers with detail by single years of age, race, sex, and Hispanic origin. These datasets are located in the nchsbri directory of our data archive. Note that we are starting a new decade here, so the new files will contain only the vintage 2020 estimates. Next year’s updates will include 2020 and 2021, and so on for the rest of this decade.
  • New 2020 data for the State/county annual population change, Population trends with demographics, and Population estimates by age applications.

As always, please contact the MCDC website manager with any questions or comments.

PL94-171 Redistricting Data is In

The PL94-171 (redistricting) data from the 2020 decennial census is now available in the MCDC data collection.

This is the first major data release of the 2020 Census, comprising race / ethnicity / voting age demographics, along with housing tenure, for all U.S. geographic areas down to the census block level.

MCDC’s new collection (/data/pl942020) includes data for all 50 states, the District of Columbia, and Puerto Rico. The collection contains two datasets per state, one each with totals ([SS]sums) and detail ([SS]detail). The sums datasets will be most useful for our regular users.

According to the U.S. Census Bureau,

Public Law (P.L.) 94-171, enacted by Congress in December 1975, requires the Census Bureau to provide states the opportunity to identify the small area geography for which they need data in order to conduct legislative redistricting. The law also requires the U.S. Census Bureau to furnish tabulations of population to each state, including for those small areas the states have identified, within one year of Census day.

Over the coming days and weeks, we will add more datasets to this collection, including U.S. level and some trends.

For questions or technical assistance, please contact Glenn Rice at MCDC.

Equal Employment Opportunity (EEO) Tables for 2006-2010

MCDC is pleased to announce the debut of the 2006-2010 Equal Employment Opportunity (EEO) Tables in our data archive.

The Census Bureau’s EEO tabulations have served as the primary external benchmark for comparing the race, ethnicity, and sex composition of an organization’s internal workforce, and the analogous external labor market, within a specified geography and job category. These are used by organizations to develop and update their affirmative action plans.

MCDC currently has two sets of Equal Employment Opportunity tabulations (aka EEO tabs) in its data collection. In the next few months, we will be adding the latest EEO tabs (2014-2018) to our collection as well.

As always, please contact the MCDC website manager with any questions or comments.

Data Updates (June 2021)

The Small Area Health Insurance Estimates (SAHIE) program data is now located in its own directory (sahie) in our data archive.

We’ve updated our SAS datasets pertaining to population estimates.

  • Population and components of change estimates: 2020 data added for Missouri and USA. These datasets are located in the popests directory of our data archive. The uscom20 dataset includes estimates of the total population of counties, states, and the US for July 1 of each year from 2010 to 2020, along with annual birth, death, international and domestic migration estimates (the components of change). The ushuest2020 dataset includes estimates of total housing units by county for each year from 2010 through 2020. The ussc20 dataset includes estimates of the total population of places (cities) and other subcounty geographic areas for each year starting with 2010 and ending with 2020. All of these datasets have corresponding Missouri-only versions, e.g. mohuest2020 for MO housing unit estimates.
  • Curmoests (current MO estimates): This Excel spreadsheet includes the latest available (July 1, 2020) population estimates for Missouri counties and places (incorporated cities).
