What is the most common negative effect of emigration on the country of origin?

The most common negative effect of emigration on the country of origin is the loss of working-age population to another country. When individuals migrate abroad, particularly those who are of working age, it reduces the labor force in their home country. This can lead to significant economic challenges, such as decreased productivity and a shrinking tax base, which can undermine public services and social programs.

Additionally, a diminished working-age population can negatively impact the demographic balance, leading to potential issues with an aging population that is not adequately supported by a sufficient workforce. The loss of a substantial portion of the labor force can also hinder economic growth and innovation, as fewer people remain to contribute to the economy and to the community's overall development.

While effects like brain drain and cultural identity loss certainly have their implications, the immediate and observable effect on economic viability generally ties back to the working-age population leaving the country.
