This is also called as a rural exodus.

It is based on the look of young people or workers in rural areas, who even more in the industrial revolution and 20th century saw more growth, migration occurs in search of job placement and also of profession, for more than obvious reasons, given the great geographical differences that exist between the opportunities, number and characteristics of the different types of employment that exist in the countryside, in relation to the city, in addition to the changes in the social, cultural and environmental aspects of urban life.

Explanation:

The aggravation at the social level of this is that rural labor begins to be displaced or begins to have little human resource, therefore the food supply or exports of agricultural products abroad fell noticeably, affecting the economy of these countries.

Some believe that living conditions in the city are better, which is why many who made the rural migration or exodus were looking for better access to the health system, or progress in areas where it provided them with a better economy at the expense of less effort.
