Population and brain cancer cases in New Mexico counties during 1973--1991.

A dataset containing the population count and number of brain cancer cases in the counties of New Mexico during the years 1973--1991. The population numbers are interpolations from the censuses conducted in 1973, 1982, and 1991. Interpolations were done using a quadratic function of time. Thus the year-to-year changes are overly smooth but match the census numbers in the three years mentioned.
