Why Are My Census Tracts Not Mapping Correctly?

If you are using Maptitude 2022 or later with the US country package, what you are seeing is a standard discrepancy between 2010 and 2020 data. Each decade the Census Bureau conducts its decennial 100% count of population for legislative apportionment. In order to do this work, they develop census tracts (hence the word Census in the name) as a tabulation layer. While census tracts are the most stable census geography from decade to decade, the tract codes and boundaries can and do change. You will find a detailed and informative discussion on this here: https://www2.census.gov/geo/pdfs/education/CensusTracts.pdf.

The tracts in your data are using 2010 delineations rather than the now current 2020 delineations. Those tracts that are showings as "voids" do not exist in the 2020 geography. However, the 2010 geography is still present so you can use that to map your 2010 records instead.

Use my earlier version of the USA Tracts


If you have an earlier version of Maptitude, the easiest way to map your tract records is simply by using an earlier version of the country package data:

  1. Choose File>New Workspace...
  2. Click the Change Country button.
  3. Choose the USA country package for 2020 or older.

 

Add 2010 Tracts to a map


Alternatively, you can add the 2010 tract layer to any map by doing the following:

  1. Open an existing workspace or make a new workspace
  2. Go to Map>Layers
  3. Click "Add Layer"
  4. Go to C:\ccdata\USA (HERE) - 2021 Quarter 4\ccFFIECTract.Cdf

In this case, since the added tract layer is not the native tract layer it will not automatically be used when geocoding, creating territories, in maps, or when using Find. If you need to locate points by census tract, instead go to Locate>Locate by Value and compare to the FFIEC Tract layer, making sure to match the tract code field in your data to the [2010 FFIEC Tract] field.

For anything else like making territories from, creating color themes on, or joining data to the Tract layer, you can just use the FFIEC Tract layer when indicated instead of the regular Tract layer.

 

Replace 2020 Tracts with 2010 Tracts


If you would like to have the interface working with all of the new data but with old tracts, use the following steps to modify your files:

  1. If you haven't already, open the 2010 FFIEC Tract layer using the steps above
  2. Go to Tools>Editing>Layer Manager
  3. Choose "Census Tract" from the Layer pulldown and click "Rename"
  4. Rename this layer to "ccTract2020", make sure its saved in C:\ccdata\USA (HERE) - 2021 Quarter 4 and click "Save".
  5. Choose "FFIEC Tract" from the Layer pulldown and click "Rename".
  6. Rename this layer to "ccTract", make sure its saved in C:\ccdata\USA (HERE) - 2021 Quarter 4 and click "Save".
  7. In the Display Manager right click on "Census Tract" and rename to "Census Tract 2020" and check Change Permanently.
  8. In the Display Manager right click on "FFIEC Tract" and rename to "Census Tract" and check Change Permanently.

 

Maptitude will now default to using the 2010 tracts, and you can add the 2020 tract layer back in using Map>Layers>Add Layer.
