Population Density of Residential Areas of St. Petersburg as an Indicator of the Urban Environment Quality

The incompleteness of the existing list of indicators of the quality of the urban environment is shown. Micro- and meso-urban geographical studies will allow for a more correct assessment of the current state of the urban environment. The integral indicator "Urban Environment Quality Index" requires the inclusion of additional indicators (population density, density and number of floors of buildings), which have a direct impact on the comfort and quality of life of the population. The population density indicator is important, which can be calculated at different levels of administrative division. Specific examples of the cartographic display of this indicator are given.
