For this purpose, key indicators housing in for 2011-2021 were analyzed. use Big Data (data from mobile operators) made it possible determine actual change density 2018-2019 largest scale cells 500 by m. present according operators’ data weekday winter nights 2018 2019 compared with growth stock considered period. established dependence these can later be used predict intracity dynamics studies risks, when longer time series become available Moscow. In addition, also factors increasing districts associated construction. It was found that due limited free land resources construction territory Old Moscow, most are localized areas increased engineering-geological technogenic danger. Additional risk an increase number storeys building They characterized a steady positive trend over period under review.
