Code for the county of the patient’s residence at the time the tumor was diagnosed is a derived (geocoded) variable based on Census Boundary files from 2020 Decennial Census. This code should be used for county and county-based (such as CHSDA) rates and analysis for all cases diagnosed prior to 2020-2029. Recording a county at diagnosis that reflects the relevant date (decade) and relies on geocoded data will improve the accuracy of county and census tract assignments and of links with geographic data (i.e., population, poverty category, urban/rural designation).

001-997 |
County at diagnosis. Valid FIPS code. |
998 |
Outside state/county code unknown. Known town, city, state, or country of residence but county code not known AND a resident outside of the state of reporting institution (must meet all criteria). |
999 |
County unknown. The county of the patient is unknown, or the patient is not a United States resident. County is not documented in the patient's medical record. |

Not tracted. |
Note: For U.S. residents, historically, standard codes are those of the FIPS publication “Counties and Equivalent Entities of the United States, Its Possessions, and Associated Areas.” These FIPS codes (FIPS 6-4) have been replaced by INCITS standard codes, however, there is no impact on this variable as the codes align with the system the Census used for each decennial census and will automatically be accounted for during geocoding.
No County at DX Geocode2020 at admission. Variable created at tumor. Set to blank for new cases.
Whenever Census Tract 2020 is changed, County at DX Geocode2020 must be changed accordingly:
If Census Tract 2020 is '999996' or '999997' (waiting for geocoding) then County at DX Geocode2020 must be blank.
If Census Tract 2020 cannot be tracted (999993-999994 or 999998-999999) then County at DX Geocode2020 must be 999.
If Census Tract 2020 is tracted and a County at DX Geocode2020 is available (whether through geocoding or linking a tumor with a tracted address) the available County at DX Geocode2020 code should be used.
However, if Census Tract 2020 is tracted but County at DX Geocode2020 is not available, County at DX Geocode2020 should be set to blank.
