Can you please list two effects of emigration in a country?

(Home country) Migrants often send home money (i.e., remittances) that benefit those left behind by increasing their consumption and improving their living conditions. At the same time, migration disrupts family life, which could have negative effects on the well-being of migrant-sending households living in the countries of origin.

(Affect)
Potentially the most important effect of emigration is on political institutions and social attitudes. There is now solid evidence that emigrants can be influential in their home societies. Students from poor countries who have studied abroad in democracies and then return home bring with them pro-democracy attitudes.

Urban growth invariably feeds increased commercialization and industrialization. it requires continually expanding land areas. when urbanization rates are high, and countries do not have the institutional and managerial capacities or economic wherewithal to manage such rapid growths, they exert intense pressure on the types and nature of the resulting settlements. they contribute to the development of overcrowded slums and shanty towns without adequate essential services and necessary infrastructure.-by asit k. biswas and cecilia tortajada
