The article is dedicated to the study of the types of migration, the current challenges of emigration and immigration, and the reasons for migration in Armenia, as well as its consequences on the economy and demography. The methods of comparative studies, general scientific analysis, groupings, and generalizations were mainly used in the framework of the research. Emigration has become one of the most drastic challenges in Armenia for almost three decades. There are a lot of reasons for emigration to Armenia: social, economic, psychological, and security. From 2012 to 2019 about 91% of those who emigrated from Armenia were in the 15-59 age group, and more than 65% were in the 20-49 age group. The latter significantly influenced the formation of the age structure of the population. In other words, the negative impact of emigration has begun to be reflected in demographics as well.
