Adult leukemia: a spatial analysis.

A simple and direct analysis of the spatial distribution of adult leukemia data results from a geopolitical map transformed to have a uniform density of the population at risk. Geographic displays and statistical assessments then lead to a series of informative descriptions of the observed spatial pattern for six sex- and age-specific categories of non-Hispanic white individuals. Using a statistical/graphical approach, no consistent pattern of disease is observed; however, indications emerge of isolated nonrandom influences among young females (ages 10-29 years).
