| 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. | ||||
