This article displays the results of assessment of environmental and economic well-being of municipal
territories of the Republic of Tatarstan. The authors developed a method to assess people’s quality of life from
the environmental load. The mathematical model of the impact of the environmental well-being in people’s life
expectancy, fertility and mortality. To analyze the effects of environmental conditions on the quality of life of
individual administrative districts and regions of the Republic of Tatarstan, first we have assessed the level of
individual well-being and environmental stress areas. In was based on the methodology of constructing
composite indices. This resulted in the comprehensive indicators of habitat quality (KSO) and welfare (HPI).
Was further developed by the authors calculated index IP. IP index shows the ratio between the level of welfare
of the population and the level of environmental protection. We have introduced an innovative index to
determine the so-called environmental "price" of the welfare of the population, this region provides a direct
opportunity to develop a system of measures of state influence on the ecological environment in order to
optimize the socio-economic development of the territory. Assessment tool developed by the well-being of the
population on the environmental load of the region can highlight areas of particular risk (in terms of the
environmental component) for which you want to develop measures to improve the environment and balanced
