How & Why Michigan Demographics are Changing
  .. learning how Michigan demographics are changing
  .. using interpretative data analytics; tools, data & methods
  .. topics & insights for stakeholders

... did you know? While the total population of Michigan is projected to change very little between 2020 (10,070,627) and 2030 (10,046,115) or -0.24%, individual counties are projected to experience greater growth and decline. For instance, based on ProximityOne model-based estimates and projections:
  • Between 2020 and 2025, Wayne County’s total population is projected to decrease by 3.4% or a little more than 60,000 people, from 1,789,586 to 1,729,382.
  • Over the entire decade, from 2020 to 2030, Wayne County’s decrease is projected to be 6.3%, or more than 113,000 people, from 1,789,586 (2020) to 1,676,373 (2030).
These projections are based in part on Census-sourced model-based population and components of change estimates 2020-2023 released in March 2024. The Census Bureau does not develop projections for this summary level.

.. and that the dependency ratio in 2020 was 64.96 for Michigan compared to 63.64 for United States? See the full Michigan-United States comparative analysis profile.

.. and that Michigan congressional district 07 had 0.6% percent population change, 2020-2022 with 2022 median household income ($MHI) of $74,404. Find out more about MI07 and how it related to other CDs using the interactive table below.

Welcome to this section focused on How & Why Michigan Demographics are Changing .. providing data and insights not available elsewhere. This section is not only about demographic-economic characteristics and how they are changing. It also discusses tools that stakeholders can use to examine different geography or subject mattter. This section assumes general familiarity with American Community Survey (ACS), decennial census and related terminology. Much of the data and graphics reviewed in this section have been developed using the ProximityOne CV XE GIS software and related Michigan GIS project. This GIS project may also be accessed online using VDAGIS tools. See more about this section.

Congressional Communities, as mentioned above, are a new geography being introduced by the nonprofit of the same name. Congressional districts are sub-divided into Congressional Communities (CCs), sets of contiguous blocks/block groups, that are typically around 45,000 population based on a range of socioeconomic, geopolitical features, geographic and other factors. The approximate 7,400 Congressional Communities cover the United States wall-to-wall and nest exactly within the corresponding congressional district. CC demographic and geographic makeup of CCs often differ from the corresponding congressional district. CC offer the opportunity for CC residents/stakeholder to better have their voices heard by congressional policy-makers and other legislative entities. A set of Census 2020 and American Community Survey demographics are developed for each CC. These demographics help CC stakeholders better understand characteristics and needs of their CCs and other CCs.

08.1 Voter Turnout & Registration
Voter turnout for the 2022 U.S. congressional elections was the second highest for a nonpresidential election year since 2000, with 52.2% of the citizen voting age population participating. Voter registration rates were the highest for a midterm election since 2000, with 69.1% of the citizen voting age population registered to vote, up 2.2 percentage points from 66.9% in 2018. These data are based the Current Population Survey (CPS).

For the 2022 elections, 31.8% of all voters cast ballots by mail, up from 23.1% in 2018. 47.1% voted before Election Day, up from 37.8% in 2018.

08.2 Examining Voting Demographics using VDAGIS .. goto top
Geographic Information Systems (about GIS) enable the user to dynamically, flexibly create maps and perform geospatial analyses.

You can use various VDA tools to examine voter and related demographics for anywhere in the U.S. Use the Open VDA Web GIS .. see more about OVDAW The following application provides an example focused on Citizen Voting Age Population (CVAP) by census tract in the Allen Park, MI (Detroit) area using Open VDA Web GIS.

All you need is a browser and Internet (mobile devices not recommended due to screen size). No registration or login required. Nothing to install.

The CVAP for an area tells us the size of the population eligible to vote in an area, such as a census tract. If all residents of an area are citizens, the CVAP would be close to the number of registered voters and enable maximized voter turnout. For some applications, CVAP might be expressed as a percentage of the total population. CVAP data are statistics developed from the American Community Survey (ACS2022) and subject to errors of estimation. Voter registration data are developed from administrative data and subject to a range of other accuracy issues.

Despite the inherent estimation errors, CVAP is an important piece of information, particularly for voter registration drives, get out the vote efforts, advocacy outreach, and voter registrars. When layered with registered voter files, VDA tools can allow users to quickly identify areas with concentrations of unregistered voters as well as bloated voter rolls.

Proceed with these steps:

1. Click to start OVDAW

2. Key "Allen Park, MI" (no quotes; any address also works, or latitude,longitude) into search bar and press Enter
  .. the map refreshes with a zoom to that location and shows the location with a blue marker.

3. In the legend panel at left, check on the "Tracts Code" layer.

4. Add Table/Grid view: click circle-A button at right below map window

5. Queries
Queries operate on the tabular data restricting the scope of data to exactly what is relevant to the anlaysis. Even though writing queries requires some basic coding skills, queries unleash the ability to explore the data the user wants to see. Many websites that provide data, do not give the user this flexiblity.

In this example, we are going to locate all census tracks in Wayne County, MI, that have a Citizen Voting Age Population (CVAP) that exceeds 40% of the tract population. We will also restrict the scope of data to include only tracts that have a total population of 4,000 people or more. In other words, we will only see tracts that show CVAP of 1,600 people or more (40% of 4,000+). The selection of 40% is somewhat arbitrary .. we want to examine tracts with a relatively high CVAP%. The selection of 4,000 population is somewhat arbitrary .. we want to examine larger tracts.

How to create and run a query
Add Query settings (in the SQL Filter box above the table):
  Query (copy the following line and paste into the SQL Filter edit box):
  select geoid, d001, d089, 100*d089/d001 where d001>4000 and geoid like '26163%' and 100*d089/d001>=40
  Sort (copy the following line and paste into the SORT edit box to right of SQL Filter edit box):
  100*d089/d001 desc
Click query button; view should appear similar to view below.

Explanation of the query used
Reference to "geoid like '26163%'" says to limit the scope of geography to state+county 26163 (Wayne County, MI)
Reference to "100*d089/d001>=40" says to show only tracts where percent CVAP is greater that 40%
D089 is the Citzen Voting Age Population (CVAP)
D001 is the total population

CVAP Patterns by Tract; Allen Park, MI Area .. goto top
The graphic below is a screen capture of OVDAW showing a zoom-in to the Allen Park, MI area. The map graphic shows census tracts labeled with census tract code. Optionally click an artibrary tract; it highlights and profile is shown at lower left in graphic.

Click to view an extended view of settings.

For example, click the tract labeled 26163576100 (census tract code) in the map; a profile appears in the lower left.
Click the HTML button below the profile; an organized display of the subject matter items appears in a new tab.
See on line "D089" that the Citizen Voting Age Population is 5,157 in this tract.

Increasing voter turnout .. actionable steps from these analytics.
1. from the table, tracts with a high %CVAP are known ("new information")
-- the voter registration for these tracts might be compared to the CVAP number.
-- if the voter registration is far below the CVAP, these areas/tracts might be prioritized for maximizing voter turnout.
2. from the map, the areas/tracts with the higher %CVAP can be visually idenfified.

The 118th Congress runs from January 1, 2023 through December 31, 2024. The 2024 House of Representatives elections will be held on November 5, 2024, to elect representatives from all 435 congressional districts for the 119th Congress. Those elected will serve in the 119th Congress with seats apportioned among the states based on the Census 2020. Using census block level data from Census 2020 each state redistricts their apportioned number seats with new boundaries for the 2024 elections. While most 119th congressional district boundaries will be the same as the 118th CD boundaries, some change occur due to 2024 redistricted states. The 118th CD boundaries are provided to the Census Bureau by states and are integrated into the TIGER public use digital map database released in 2023. More detailed 118th congressional district demographic-economic data are available from the ACS 2022 released in 2023.
