Contextual Data Archive (CDA) Data Set No. M1-M3

Metropolitan Statistical Areas, 1970, 1980, 1990

The U.S. Office of Management and Budget (OMB) defines metropolitan areas (MAs) according to published standards that are applied to Census Bureau data. The general concept of an MA is one of a large population nucleus, together with adjacent communities that have a high degree of economic and social integration with that nucleus. Some MAs are defined around two or more nuclei. Data set M1-M3 of the Contextual Data Archive includes socio-economic and demographic data for Metropolitan Statistical Areas (MSAs) in the US. M1 consists of data from the 1970s and has 280 cases and 338 variables. M2 covers data from the 1980s, and includes 556 variables for 363 cases. M3 covers data from the 1990s and includes 330 variables for 335 cases
