Geocorr and Other Application Updates (December 2023)

Posted on by glenn

MCDC has a number of significant application updates to announce this month.

We added several new geography types to the Geocorr 2022 application, including the new core-based statistical areas (CBSAs, which include metropolitan and micropolitan statistical areas), metropolitan divisions, and combined statistical areas (CSAs), all of which were released by the Office of Management and Budget in July 2023. We also added the “new” Connecticut planning regions, and updated the urban areas to match those currently used by the Census Bureau.

The Connecticut planning regions pose a special problem for those using Geocorr to do county-level correlations. Earlier this year, the State of Connecticut finalized adoption of the State’s nine Councils of Governments (COGs), also called planning regions, as the county-equivalent geographic unit. Unfortunately for longitudinal county-level data users, the new regions don’t match the boundaries of the state’s eight counties that were previously used for census data tabulation.

In Geocorr, we’ve designated the planning regions as a new geography type that exists only in Connecticut. The unwanted consequence is that if you try to run a correlation using the new planning regions with any state besides CT, you’ll get an error. Thus, if you want to run a county-to-target correlation for many states or the whole nation, you’ll need to run it twice: once with all the states except CT, and then a second run to do the region-to-target correlation just for CT.

For more information about the CT changes, see Final Change to County Equivalents in Connecticut and the Final Federal Register Notice, Change to County Equivalents in the State of Connecticut.

Two other MCDC data applications have also been extensively updated: Population Estimates by Age and Population Trends with Demographics. The earlier versions of these apps relied on the so-called “bridged-race” single-year-of-age data from the National Center for Health Statistics (NCHS). Unfortunately, this very valuable data source was discontinued in 2020. These applications now use the annual population estimates published by the Census Bureau’s Population Estimates Program. Rather than single-year-of-age data, these estimates are aggregated into 18 five-year age “buckets” or cohorts. Therefore, it’s no longer possible to extract single years of age or make custom cohorts with the MCDC apps. Moreover, the census race classifications changed in 2000. Before then, there was not a separate race category for “Hawaiian and other Pacific Islander”. These populations were included in the “Asian” category prior to 2000. In addition, there was no category for “Two or more races” before 2000. Please exercise due caution when using pre-2000 population estimates from our applications and from the Census Bureau sources.

Data Updates (September 2023)

Posted on by glenn

We have a few routine data and application updates to announce this month.

  • On August 24, we posted new a zcta_master set to our geographic reference data collection. Zcta_master is a comprehensive ZCTA (ZIP Code Tabulation Area) resource with geographic correspondences and vintage 2021 ACS-based demographics. This new version uses ZCTAs as defined for the 2020 census. We have our usual SAS dataset, accessible via the Dexter data extraction tool, as well as a CSV file.
  • We found some minor errors in the new DHC data collection. Tract codes were missing final digits. These have been corrected.
  • Two of our workhorse data applications, uex2dex and Dexter, underwent substantial code updates and revisions.
  • Just this week, we published the 2022-vintage round of intercensal population estimates, released earlier this year. These include the CASRH (characteristics of age, sex, race, and Hispanic origin) data for all states, population ranks, housing unit estimates, and the new “curmoests” Excel file (Missouri current population estimates for the state, counties, subcounty units, and cities and towns).

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

Data Updates (September 2021)

Posted on by glenn

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

Posted on by glenn

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

Posted on by glenn

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.

Data Updates (June 2021)

Posted on by glenn

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).

We’ve updated many of our population-related applications and datasets over the past couple of months.

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

Missouri County Pages Are Back

Posted on by glenn

After a very long hiatus, the application formerly known as “Missouri County Pages” is back in operation. We’re now calling it “Missouri [County] Fact Sheets”, and a few of the old data variables have been replaced. Otherwise, the application has similar appearance and functionality to the old version.

The Missouri Fact Sheets application generates a report for any county in Missouri, including population trends, age and race, income, employment, agriculture, households and housing, poverty, education, and children and families.

See it in action here: http://mcdc.missouri.edu/applications/MO-county-factsheets/.
