Census Tract 2010

Field Length:  6

This field is provided for coding census tract of patient's residence at time of diagnosis. Codes are those used by the U.S. Census Bureau for the Year 2010 Census. Census tract codes have a 4-digit basic number and also may have a 2-digit suffix. Census tract numbers range from 0001.00 to 9999.98.

The Census Bureau provides population data for census tracts. Those rates can be used for general surveillance or special geographical and socioeconomic analysis.

Because census tracts for particular cases can change between censuses, the central registry may wish to assign an alternate census tract code to its cases. For example, a registry may code its 2005 cases using both the 2000 and 2010 census tract boundaries. The central registry can use this information for different comparisons.
