LOINC description : This field is provided for coding census tract of patient's residence at time of diagnosis.
See Census Tract 1970/80/90 [110]. Codes are those used by the U.S. Census Bureau
for the Year 2000 Census. Census tract codes have a 4-digit basic number and also
may have a 2-digit suffix. Census tract numbers range from 0001.01 to 9999.98. See
the Census Bureau's Area Classifications at the following website: http://www.census.gov/prod/cen2000/doc/sf1.pdf
for further details. 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 2000 Census tracts to tumors diagnosed in previous years, without
losing the codes in data item 110. 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 1985 cases using both the
1980 and 1990 census tract boundaries. The central registry can use this information
for different comparisons... NAACCR Data Standards and Data Dictionary Version 11;
