Abstract:

The article is devoted to the analysis of theoretical and practical features of the quantitative and qualitative assessment of the influence of the income of the population of Ukraine on migration processes. Net migration in the country was considered as the main indicator of the state of migration processes in Ukraine, and the amount of available income per person and its separate component - the level of average wages - were chosen as factor indicators. The application of correlationregression analysis methods confirmed the high closeness of the correlation between the variables of the const
