What is the impact of rural-urban Migration on the age and sex structure on the place of origin and destination ?
Migration leads to redistribution of population within a country. Rural-urban migration is one of the important factors contributing to the population growth of cities. Age and skill selective out migration from rural areas have adverse effect on rural demographic structure. High out migration results in serious imbalance in age sex composition. Male population within the working age group migrate out of rural areas leaving females, children and old aged people, which increases the share of dependent population in rural areas. The stuation is especially difficult for females because they have to look after both domestic and economic work in the villages, leadings to higher participation of women in agriculture without decrease in their household workload. Also it leads to loss of human resource from the rural areas, leaving them with unskilled people thus reducing the total productivity and hence hampering the development of rural areas. Urban areas receive heavy in migration of working age male population, causing sex ratio to be highly unfavourable for females, which gives rise to crimes against women and increase their vulnerability.
