Abstract
Today, many more communities in the United States are in a better position to undertake the study of the possible health effects of the air pollution in their environment than has been possible before. Further, such study may furnish baseline data for evaluating the efficacy of air pollution control activity in those cities.
Assessment by city and county control officials can be accomplished by examining the relationship between the demographic characteristics of the area as reported in the 1970 Census of Population, the aerometric measurements now being made routinely in many areas, and mortality in the population as reported to the state office of vital statistics. From the census, detailed demographic or population data will be available by census tract in urban areas. These areas include virtually every U. S. city with a population of 50,000 or more.
The procedures used in the Buffalo and Nashville Air Pollution Studies are discussed with a view toward possible replication by other geographic areas. The need to take account of differences in socio-economic status is emphasized, as is the desirability of obtaining smoking histories. Another major type of air pollution research which is again made possible by the 1970 Census is the comparison of mortality experience, on an agespecific and an age-adjusted basis centered around 1970, for the more than 200 Standard Metropolitan Statistical Areas in the United States.
