Most studies show that the members of rural communities who are most likely to migrate to urban centers are those who have been to school. The studies seem to show a consistent positive correlation between an individual's level of education his propensity to migrate. REASONS (1) The income gap between what the 'educated' ones can earn in urban areas compared with their rural opportunity cost is larger than it is for the illiterate ones.(2) The educated ones are more likely to obtain a lucrative modern sector job. But because jobs are scarce,a large proportion of those who migrate often remain unemployed.
This isn't just the general purpose of migration but there are other ones like traders. People that are into business migrate from rural areas to urban. There is this particular tribe from my country, they called them IGBO, this people don't really give much attention to education, there foundation has always been about trades, out of 10 popular European countries that you know, you will find a male and female egbo person there and whne you check there lifestyle, they are trade based individuals with common goals.
People that are educated that migrate from rural areas to urban places are mostly people that are looking for careers opportunity. If you are from are a rural area and you study accounting, there is no future for you staying in the village if you have the plan to use that certificate for your career. You have to go to the urban/city where that job is very need of your service, you can't be an public admin and want to stay in a rural area, your career might just die.
