This report presents statistics from the 1970 census, by blocks, on general characteristics of housing units and population.

This report series contains 278 reports (as listed on page II). Most of the reports (236) relate to a specific urbanized area, as well as to some nearby contiguous territory in·eluded for reasons explained in the section on "Urbanized areas." The remaining reports (42) relate to other types of areas (e.g., smaller cities, counties, etc.) where local authorities contracted with the Census Bureau to collect, process, and publish the data on a block basis. A major portion of the information compiled from the 1970 Census of Housing will appear in Volume I, Housing Characteristics for States,Cities, and Counties.

The maps included with these reports identify the location and number of each block and the boundary and number of each census tract or block numbering area.

ln the urbanized area block publication program, table 1 summarizes the statistics for each place of 2,500 inhabitants or more and table 2 contains the statistics for the individual blocks summarized to the tract or block numbering area. In the contract block program, one table provides statistics for individual blocks as well as summaries for each tract or block numbering area and each place or area. In some instances, the blocked area excludes a part of a tract or excludes the rural portion of an extended city (a city having one or more large portions, usually at the boundary of the city, with relatively low population density). Therefore, the tract and place totals cover only the blocks included in this report. Block identification, total population, and total year-round housing units are shown for every block containing living quarters. For some blocks, the table shows total population but no housing units because all the people live in group quarters. For other blocks, the table shows housing units but no population because all the units are vacant. Blocks (or tracts) with no year-round housing units and no population are shown on the map but do not appear in the tables.
