Аннотация:This article is devoted to the study of the impact of the COVID-19 pandemic on the processes ofsub- and de-urbanization in Russia and the specifics of the return and seasonal dacha mobility of urban population. The features of the mass departure of citizens, especially Muscovites and residents of cities of Moscow oblast, to dachas in 2020 are considered. The introduction of the restrictions and the use the possibilitiesof remote work and education contributed to the departure from large cities. Financial and socio-organizational, opportunities for the transition the summer seasonal mobility to real sub- and de-urbanization in areas are analyzed. Regions of varying degrees of remoteness from Moscow and major centers are considered: in the near and far municipalities of Moscow oblast, in the south and north of Yaroslavl oblast and in a remotearea of Kostroma oblast. It is shown that the real readiness for sub- and de-urbanization, even in a crisis period, depends on the distance from city and development of the infrostructure. Moscow oblast is characterized by longer residence in dachas in 2020, including the cold season. This indicates the psychological readiness of the Muscovites to move outside the city. Here stressful suburbanization partly develops into thepermanent type. At medium-distance and distant dachas, there are not enough conditions for the de-urbanization of citizens (except for individual enthusiasts). The poor quality of roads, the lack of gas and water supply in the very heart of Russia, and lack of interest of local authorities in new residents from cities, make theflow of Muscovites and other city residents to the countryside pulsating and unreliable.
