We assessed the occurrence of malignant melanoma of the skin in New Mexico from 1969-1977. Incidence data, collected by the New Mexico Tumor Registry, were supplemented with mortality data supplied by the State Bureau of Vital Statistics. These data were analyzed for variation by site, sex, and ethn

Abstract
Incidence and mortality rates for malignant melanoma of skin in the New Zealand nonโMaori population over the past 30 years were analysed in relation to sex, age, birth cohort and time. In both sexes, the ageโstandardized incidence rates increased approximately exponentially with time, with an annual increment of 7.5%. The ageโstandardized mortality rates increased approximately linearly with time, resulting in a twoโ to threeโfold increase over 30 years, as compared with an eightโ to nineโfold increase in the incidence rates. Descriptive birth cohort analysis shows different patterns of increase for incidence and mortality rates. The main difference is that, whereas incidence rates have continued to increase in recent birth cohorts, mortality rates have stabilized. The explanation for this difference is uncertain.

The incidence of cutaneous malignant melanoma (CMM) has been rising in fair-skinned populations throughout the world for decades. The upward trend may, however, finally be slowing in some of these populations. Recent (1983-1996) CMM incidence trends for a high incidence area (New South Wales, Austra

All records of ocular malignant melanoma notified to the Danish Cancer Registry between 1943 and 1982 were re-coded, and 1,624 out of 1,650 cases were verified and included in this investigation. The annual number of incident cases increased from about 30 to 50, but the age-standardized incidence ra
