Census tract of usual residence when this tumor was first diagnosed, using 2010 census tract boundaries used by the U.S. Census Bureau for the Year 2010 Census.
Census tract codes allow central registries to calculate incidence rates for geographical areas having population estimates. This field allows a central registry to add Year 2010 Census tracts to tumors diagnosed in previous years, without losing the codes in data items 110 and 130.

Census tract codes are provided by a vendor that is under contract with the CCR to geocode patient addresses. If an address and its assigned census tract goes to IPAQ after being returned from the geocoding vendor, the census tract can be changed by an authorized user. The authorized user should first check with the CCR-approved publicly available address locator, AmericanFactFinder.

Census tract codes have a 4-digit basic number and may have a 2-digit suffix. For example: Census tract 0145-05 is coded as 014505.

999999 |
Not a California residence (includes UNKNOWN state) |
No Census Tract 2010 variable at admission. Variable created at tumor level.
Computer generated values when created:
999999 |
If State at DX not CA (includes UNKNOWN) |
999993 |
If City at DX = UNKNOWN and ZIP at DX = UNKNOWN and County at DX has valid value and State at DX = CA and Addr at DX (No & Street) has valid value including ‘UNKNOWN’. |
999994 |
If Addr at DX (No & Street) begins with PO BOX |
999996 |
If none of the above |
As census tracts are determined via the geocoding process, add to the database either manually or by computer.
Reset Census Tract 2010 to 999993, 999994, 999996 or 999999 (see Source), if TU_Addr at DX--No & Street, TU_Addr at DX--City, TU_Addr at DX--State, TU_Addr at DX--Postal Code, or TU_County at DX is changed. (Don't reset if only TU_County at DX was changed as a result of geocoding). Allow user to specify that the code should not be reset while manually changing one or more of the preceding fields
If tumors are being relinked and the addresses are identical but one case is tracted and the other is not, the tracted census values should be used.
If geocoded values from geocoding vendor are being linked with tumor and the census tract 2010 certainty value returned from the vendor is ‘9’ (census tract not assigned, geocoding attempted), the system will update, upon being linked, a census tract value of ‘999996’ to ‘999997’ or census tract value of ‘999997’ to ‘999998’.
When the variable is created at the tumor level and an address receives a value of ‘999993’, it is not sent for geocoding at the vendor. It will be reviewed so as to get better address information that may allow it to be geocoded.
