Migration in all forms and forms is a powerful demographic factor and, among other demographic processes, is an essential determinant of the structure of the population in a particular territory. The study related to migration processes and attitudes in Bulgaria is interesting as a social and economic phenomenon, which with its dynamics and the serious consequences it carries with it matters both for the national, in particular the Bulgarian and for the global economy. Demographic problems, internal migration and emigration and immigration pressures will accompany the development of Bulgaria and the Western world throughout the 21st century. We are currently witnessing massive migration flows from the Middle East and Africa to the European continent, mainly to the rich and large countries of Western Europe. Its size reaches the dimensions that give observers and analysts reason to talk about migration and future replacement of the genetic and civilization code of the continent. Bulgaria is one of the transition countries in Eastern Europe, which has a strong demographic decline. The factors that determine the great unevenness in the development of its population are the territorial changes in the first half of the last century, the internal and external migration of the population and its natural movement. The aim of the study is to identify and distinguish the factors that generate migratory attitudes in the Bulgarian population and the peculiarities of the migratory process itself. The subject of the survey is the migratory attitudes of population movement in Bulgaria and the sustainable impacts of these processes. The article uses combined general methods -analysis and synthesis, comparison, generalization, induction and deduction.
