Research of the Digital Technology Impact on the Quality of Life in the Countries of the World

The work is devoted to the analysis of the impact of digital technologies on the quality of life of the population at the micro and macro levels. The dependence of the quality of life on the development of digital technologies at the macro level has been tested by building linear and nonlinear regression models. It was found that there is a significant nonlinear relationship between the indicators of quality of life and the development of digital technologies, which can be expressed in the form of a logistic curve or modified exponential curve. Groups of countries similar in terms of digital development were also identified. Thus, three groups were identified: leading countries, developing and lagging countries in terms of access to and use of digital technologies. On the basis of the RLMS HSE database, an analysis was made of the dependence of the quality of life of individuals on the level of their use of digital technologies, such as personal computers, mobile phones, the Internet and social networks. The quality of life was determined on the basis of answers to the question of happiness and satisfaction with life. Due to the nominal ordinal scale of answers to these questions, the method of ordinal regression was used to assess the degree of impact of the use of digital technologies on the quality of life. Thus, the youngest population, actively using digital technologies, is the most satisfied with life.
