Answer:
Brain drain refers to the emigration of skilled labor from a country which therefore hampers the development of the country being emigrated from.
Factors promoting brain drain include;
- Poor quality of life - If skilled labor finds that despite being skilled and in need of better compensation for their skills, they still suffer a poor quality of life, they will leave for countries with better opportunities.
- Political instability - One of the main reasons why brain drain occurs. Professionals regularly emigrate from their country to protect their lives when there is political instability that can lead to persecutions and even civil war.
- Lack of Economic opportunities - If the skilled laborers are not being given access to enough economic opportunities to improve their lives, you will find that they will leave for greener pastures.
