Multilevel modelling of geographically aggregated health data: A case study on malignant melanoma mortality and UV exposure in the European community. Statistics in Medicine, 17, 41-58. Description: The data are from a study of the effects of ultraviolet (UV) light exposure on malignant melanoma mortality. Counts of the number of deaths due to malignant melanoma were recorded for males of all ages in the United Kingdom (UK). The counts of the number of deaths between 1975 and 1980 were aggregated over areas that correspond to counties or shires; hereafter referred to as counties. Data were collected on 70 counties nested within 11 regions of the UK. The resulting data structure is multilevel, with counties at level 1 nested within regions at level 2. The main predictor of interest is exposure to ultraviolet light in the B band (UVB). An index of UVB dose reaching the earth's surface was calculated for each county. The mean UVB index in the UK was 10.9, with a standard deviation of 1.5.
