Abstract. On October 2–6, 2019, Kyoto Sangyo University (Japan) hosted the 2nd World Congress “East-West: Intersection of Cultures”. The congress was attended by more than 200 scientists from 36 countries, including: Russia, Japan, USA, Canada, Georgia, Armenia, Belgium, Vietnam, Italy, Poland, Slovakia, Finland, China, Kazakhstan, Uzbekistan, Ukraine, South Korea. They discussed issues related to international migration and demography, education and cross-cultural communication and the problems of adaptation of migrants. The editors publish material on section “Socio-cultural studies of international migration and demography”, which discussed new trends and characteristics of demographic processes, including migration processes in countries around the world. Economic growth leads up to an increase in life expectancy, which is the reason for the demographic aging of the population of developed countries. Does this trend threaten further socio-economic development? Migration growth in developed countries aggravates the integration of new citizens, including cross-cultural interaction. What is the positive experience of these problems?
