MCDC News and Updates

Geocorr 2022

We’re happy to announce a new version of Geocorr based on 2020 decennial census geographies. Thank you for your patience!

Currently, Geocorr 2022 comprises the following geographies for all states, DC, and PR (where applicable):

  • nation (aka “Entire universe”)
  • states
  • counties
  • minor civil divisions (MCDs; includes townships and other county subdivisions)
  • tracts
  • block groups
  • blocks
  • places (towns, villages, cities, etc.) and census-designated places (CDPs)
  • core-based statistical areas (CBSAs; includes metropolitan and micropolitan statistical areas)
  • upper- and lower-chamber state legislative districts
  • Congressional districts (116th Congress)
  • ZCTAs (ZIP codes)
  • NECTAs and NECTA divisions
  • elementary, secondary, and unified school districts
  • “best” school districts and types
  • county and place size categories
  • hospital service areas and referral regions

In addition, Geocorr 2022 includes the following regions for the state of Missouri only:

  • Regional Planning Commissions
  • University of Missouri Extension regions
  • MO Dept. of Economic Development (MERIC) regions
  • MO Dept. of Transportation districts
  • MO Area Agencies on Aging
  • MO BRFSS regions

We’ll add other geography types as they become available.

Longtime users of the Geocorr applications may notice a few other changes. Geocorr 2022 does not include the concentric ring pseudo-geocode options, nor the bounding box filter option. Our server logs indicated that these options were rarely used, and in a couple of instances were not actually functional. The HTML (web page) report option is now unchecked by default. The report output is the most resource- and time-intensive block of Geocorr’s code, and frequently causes program timeouts when very long reports (e.g., those using blocks) are requested.

Although Geocorr 2022 has been thoroughly tested, it should be considered a “beta” version for the moment. Please report any errors to Glenn Rice (riceg@missouri.edu).

Story Map

Missouri Voter Turnout in General Elections Since 2000

How many people in Missouri actually exercise their right to vote?

As Missourians get ready to head back to the polls for the 2022 midterm election, our colleagues at the Missouri Spatial Data Information Service built a story map showing voter turnout for previous Missouri general elections from 2000 through 2020.

The Missouri Census Data Center frequently works with MSDIS on mapping and data projects. MSDIS is a spatial data retrieval and archival system offering many mapping resources, primarily focused on the state of Missouri.

Minor Data Updates (January 2022)

We have just a few minor data updates this month.

Story Map

Census 2020 and Missouri’s Changing Population

Last year, the Missouri Spatial Data Information Service (MSDIS) and MCDC brought you several interactive applications that focused on the US Census. We looked at what kinds of public services depend on an accurate census count for the proper distribution of funds and we explored the racial geography of Missouri at a county level. This was all in expectation of the release of the highly anticipated 2020 US Census.

Well, dearest friends and fellow map enthusiasts, the 2020 Census data is here. Let’s have a closer look at Missouri population changes since 2000 and 2010.

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.

Missouri Surpassed 6 Million Persons in the 2010s

The U.S. Census Bureau has published a collection of state population profiles for 2020 as part of its “America Counts” story series.

Missouri now has a population of 6,154,913 and 2,786,621 housing units.

Between 2010 and 2020, Missouri’s population increased by 165,986, or 2.8%. By comparison, the overall U.S. population increase was 7.4%.

Missouri’s under-18 population decreased over the past 10 years by 3.2%, while the adult population increased by 4.6%.

Some key figures about the population of the entire United States, for comparison:

  • Population was up to 331.4 million.
  • The Diversity Index went up to 61.1%, from 54.9%.
  • The under-18 population decreased by 1.4%, and the adult population increased by 10.1%.
  • The number of housing units went up 6.7%, and vacancies went down to 9.7% of all housing units.

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.
