Abstract The overall objective of this research program was to develop a method for adjusting incidence rates for migration in studies relating environmental agents to diseases with long latent periods. Various methods of estimating migration and population change are considered. An example of a situation necessitating this adjustment is described. Cancer incidence rates were compared for census tracts with varying levels of asbestos in drinking water. Since cancer has a long latent period, recent in-migrants would not have been exposed for sufficient periods of time to be at risk for cancer. Unless the in-migrants were equally distributed across census tracts, an analysis of the relationship between asbestos and cancer based on incidence rates would be biased. This report reviews a number of measures of migration and population change as well as stochastic models of migration and stochastic models of population growth. Migration data available through the Census of Population and Housing of the Bureau of the Census are described. A method is developed that uses these data to estimate migration by census tract. This method is then applied to data from a U.S. Environmental Protection Agency supported project on the relationship between ingested asbestos and cancer and the results compared to the original analysis.
