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.
