LOINC description : Description This field is provided for coding the block group of patient's residence
at time of diagnosis, as defined by the 1970, 1980, or 1990 Census. Rationale A block
group is a subdivision of a census tract or block numbering area (BNA). Not all of
the United States was described by a census block group or BNA prior to the 2000 Census,
but for such areas, the Census Bureau published detailed population and socioeconomic
data. Block groups thus offer a high level of specificity for geographical and socioeconomic
analyses, where available. A block group has no meaning in the absence of a census
tract. Refer to Census Tr Cert 1970/80/90 [364] to ascertain the basis of assignment
of CensusBlockGroup 70/80/90. Refer to Census Cod Sys 1970/80/90 [120] to ascertain
the decade of reference.;
