Researchers at General Motors collected data on 50 U.S. Standard Metropolitan Statistical Areas (SMSA's) in a study of whether air pollution contributions to mortality. The data include variables measuring demographic characteristics of the cities, variables measuring climate characteristics, and variables recording the pollution potential of three different air pollutants: hydrocarbons (HC), nitrous oxide (NOx), and sulfur dioxide (SO2). See more description of the variables in the following table. Data ("airpollution50.txt") are provided on iCollege.
