Question

Why are people migrating from rural area to urban areas

Answer 1

There are several reasons as to why people move from rural to urban areas. 
1) For better job opportunities and salary- Jobs in rural areas usually require a lot of physical effort, where as most jobs in urban areas just involve sitting behind a desk. People in urban areas are usually payed more than people in rural areas. 
2) The luxuries of the urban world attract the people of rural areas. Most rural are agriculture based. An agriculturist's needs are pretty simple. They revolve mostly around domestic needs only, whereas urban areas, everything revolves around technology that makes life easier. 
3) Large masses of people moving from rural to urban areas, causes a phenomenon called, "urbanization". Urbanization leads to overpopulation, pollution, and various other problems. Due to urbanization, the boundaries of the urban areas expand into the rural areas. This causes forced urbanization, as people who live in the rural areas are forced into the urban area and the ways of the urban people. 
4) The standards of living and the standards of education are higher in urban areas. This may also be one of the reasons why people move from urban to rural areas.
