Introduction. One of the priority socio-economic and medical-demographic problems in Russia is the high mortality. The study aim is to identify the most significant factors that determine the mortality on the example of two single-industry towns. Materials and methods. Mortality in two single-industry towns specializing in copper-nickel production, differenced in climate, environmental, and socio-economic indicators, was studied using age-standardized indicators averaged over 8 years (2010-2017). Results. In Monchegorsk, compared to Russia, with similar non-production characteristics, working-age mortality from cardiovascular diseases (CVD) was higher by 49.0%, from malignant neoplasms (MN) by 34.7%, from diseases of the digestive system by 35.5%, which confirms the negative impact of occupational factors on the mortality of the population of a single-industry city. In Norilsk city, with the worst characteristics of the environment and climate, compared to Monchegorsk, mortality from CVD was lower in working age by 40.6%, in post-working age by 41.4%; from MN - in working age lower by 37.2% that shows the compensating influence of socio-economic factors on mortality. Conclusion. Risk factors for increased mortality rates in single-industry towns with copper-nickel enterprises are the influence of harmful occupational factors, as well as environmental pollution. Along with primary prevention, an effective mechanism for reducing mortality is to improve socio-economic well-being, and the quality of medical care.
