(x,y): residential coordinates of all CGL cases registered in NW England between 1982 up to 1998 (inclusive) age: age in years sex: 1=female,0=male deprivation: Townsend deprivation score for location of residence leukaemia_NW_cases.txt: 233 cases leukaemia_NW_controls.txt: 988 controls For the selection of controls, population counts in each of the 8131 census enumeration districts that make up the study-region, stratified by age and sex, were extracted from the 1991 Census. The counts were then used to obtain a stratified random sample of two controls per case with coordinates given by their corresponding centroid coordinates (slightly jittered to avoid coincident points).
