1960 Census: Supplementary Reports: Annexations and the Growth of Population in Standard Metropolitan Statistical Areas: 1950 to 1960

PC(S1)-16

This report supplements PC(S1)-1 on the population of standard metropolitan statistical areas (SMSA) by showing annexation data, individually, for the 212 SMSAs in the 50 States and the District of Columbia. Tables 1 and 2 in the present report correct minor errors in tables 1 and 2 of that report.

In the decade 1950 to 1960, annexations had a considerable impact on the distribution of population within SMSAs. Of the 112.9 million persons living in SMSAs in 1960, approximately 58.0 million lived in central cities and 54.9 million lived outside central cities in the remainder of these areas. Of the 58.0 million in central cities, however, about 4.9 million, or 8 percent, lived in areas which had been annexed to the central cities during the decade.

Although the 1960 population of areas annexed to central cities during the decade was a relatively small part of their 1960 total, it constituted the major part of the 1950-1960 increase in these cities. The population of these cities increased by nearly 11 percent during the decade, but the rate of growth within their 1950 corporate boundaries was only about 1.5 percent. Similarly, although the suburban ring outside central cities showed an increase of about 49 percent during the decade, it would have risen to about 62 percent had there been no annexations.
