Over the years, there has been this hue and cry by government and public advisers against the phenomenon of the rural-urban drift. Researches have been conducted on various aspect of the phenomenon. Among the causes most often mentioned are population pressures in some rural areas resulting in dwindling farmland; increasing school enrolment and the resultant rise in educational levels which qualify many people for urban employment, higher wages in the urban centers relative to rural areas.
The most often mentioned consequences of this rural urban migration depopulation of the rural areas leading to overcrowding of the cities and the resultant housing and sanitation problem, decline in the agricultural population resulting in less food crops being grown and high food prices in the cities. The results of the phenomenon are seen largely as negative. When industries are located in the rural areas, it involves much less cost for the prospective rural-urban migrant to change to a non-agricultural job than us involved in his leaving a rural abode for a distant urban centre.
