Missouri Voter Registration

FairVote2020 has developed an interactive map showing voter registration rates for Missouri communities and neighborhoods in selected counties as of the January 2004. Boundaries for the thematic display are based on census block groups rather than precinct lines because there is no publicly available statewide geographic 2004 precinct database.

Zooming in to a scale of about five miles, you will see the estimated number of unregistered or inactive voters (by block group) displayed in purple boxes.

You can view socioeconomic themes -- race, ethnicity, income, access to vehicles, etc. -- for these neighborhood areas by selecting maps from the drop-down menu under "Compare Maps" on the left. These maps also show block group-level detail, providing an exact boundary match to the voter registration data.

Below the links to the interactive maps is a link to a directory with about 500 maps in Adobe format -- printer-ready and PDA compatible. These maps show street-level detail for areas where 40% or more of the voting age population is minority, with an estimated 200 or more unregistered or inactive voters. There are an estimated 212,000 unregistered or inactive voters (all races) in the focus areas, representing about 55% of the resident voting age population. About 45% of Missouri's minority population lives in these areas.

There is also a link to Adobe maps showing neighborhood registration rates for all Missouri localities with populations greater than 15,000. A link to a second set of maps for the same places displays Bush-Gore by precinct.

Map 1 (default map) -- Unregistered or Inactive Voting Age Population in 2004

At a scale of about 5 miles, the estimated number of voting age persons (by block group) who are unregistered or inactive is displayed in purple boxes. When you click on ZOOM TO and then click on the map -- voter registration and demographic data for the block group selected will appear in a table below the map. Click on INFO and then click on the map for more detailed data.

At a scale of about 3 miles, green labels showing the block group numbers can be displayed by checking the box next to "BG FIPS code" below the map image. (The five digit state-county portion of the number, e.g. "29510" is not shown in the map -- 29 is for Missouri and 510 indicates St. Louis City -- but is displayed using the INFO button and must be entered for searches based on the block group code using FIND. )

Precincts in effect in 2000 (called VTDs) can be identified by clicking on INFO and then on the map. The precinct number is the last item in the pop-up window.

This map is based on a January 2004 statewide registered voter file. For the map theme, we eliminated from the registered count anyone who had not voted for the previous six years or who was identified as inactive in the voter file. Precincts in 33 counties are not displayed due to geocoding inaccuracies. The area displayed -- where geocoding was generally in the 95%+ range -- contains a total voting age population of 5.1 million persons, or 91% of the voting age population statewide.

Blank areas on the map encompass the 33 counties and other areas where the geocoding was faulty or voter data was incomplete.

Map 18 -- Statewide Focus Areas

See also Adobe maps below. This map shows block group areas with populations that are 40% or more minority, according to the 2000 census, with 200 or more estimated unregistered or inactive voters.

Street-level printer-ready, PDA compatible detail maps can be downloaded by clicking on the INFO button and then on the precinct of interest. Next select "Focus Areas" and select the Adobe map link from the lower half of the pop-up window. Right click and select Save Target As or Open in New Window.

Batch downloads for the Adobe files (organized by county, city, zip, and block group, number) can be accessed via this directory:

Statewide Focus Areas (500 maps)

These street-level maps show neighborhoods and communities with populations that are 40% or more minority, according to the 2000 census, with 200 or more estimated unregistered or inactive voters.

White numbers overlaying dots show estimated unregistered or inactive voters (all races) by census block. These dots are color-coded to show race/ethnicity components for the over 18 population residing in the census block and scaled based on the total number of estimated unregistered voters.

Census blocks shaded in grey have minority voting age populations below 40%.

The files are organized by county, city, zip, and block group number. The precinct proxy code is based on a precinct that is within all or part of the block group. Where block groups are split by precincts, only one of the precincts is identified. Precinct proxies may also encompass more than one block group.

Community-wide unregistered/inactive voter maps

Birds-eye view of neighborhood-level registration rates. The numbers displayed in purple boxes show unregistered or inactive voters and will match the unregistered voter count in the footer portion of the block-level "focus area" maps.. These maps can be used for orientation purposes with the "focus area" block-level maps above.
