Villages, as the first human settlements, have experienced different stages of growth or stop during
the process of their historical evolution and also in their encountering with development of technology and
change in structural fundamentals of societies, which has sometimes caused the increase or decrease of
population of these residential points due to migration of villagers from the area. In this regard and specially
in developing countries, attention to environmental improvement and rural development has been among basic
priorities of the statesmen of such countries. In this line rendering welfare and infrastructure amenities and
services with the purpose of getting villagers to stay in these population centers in the line with sustainable
development of villages are among the major objectives of planners and statesmen. In this research, which is
a correlative-analytical one, it is attempted to study the role and effect of government services in decreasing
rural migrations and consequently sustainability of population in rural settlements in Darab region, an environ
of Iran, using data gathered through the field study and survey. The statistical population includes 15 villages
enjoying and 15 villages lacking government services and financial facilities and using Cochran sampling
method, 220 people have been selected as sample size. The questionnaires have been randomly distributed in
villages and the correlation between variables has been measured using Spearman correlation coefficient.
The results indicate that there is no significant relation between rendering services to villages and the
sustainability of population in the studied villages. In other words, in spite of providing service and rendering
welfare-fundamental facilities by the government agencies to the studied villages, the presence of economic
problems such as lack of capital and financial resources required for production, widespread poverty, high rate
of unemployment in villages and the existence of relative surplus of labor in agriculture department have caused
migration of villagers of the area to cities and therefore, evacuation of villages from population and their
unsustainability
