Enumeration Districts, 1970 & 1980
Enumeration Districts (EDs) are the most basic work units for the Census Bureau. It is the area assigned to a single enumerator. EDs do not cross the boundaries of legal or of statistical areas, but are otherwise drawn so as to be bounded by roads and other natural features. EDs may be redrawn and renumbered for each decennial census. ED-level data are available only in untracted, unblocked areas, i.e., those areas for which tract- and BNA-level data are not available. ED-level data can therefore be used in combination with tract/BNA data to obtain complete national coverage for "neighborhoods" in both urban and rural areas.
This dataset includes socio-economic and demographic data for all Enumeration Districts (ED)s in the US. The first data file consists of data from the 1970 Census, and has 69,743 cases and 178 variables. The second covers data from the 1980 Census, and includes 227 variables for 53,658 cases. There is no data for 1990.
