Migration is a difficult concept to define because it includes people who move for different reasons across different spaces. A migrant can be a person who moves to another city or town within a nation; a refugee who crosses an international border to escape religious or political persecution; a jobseeker who moves to another country for better economic opportunities; a slave who is forcibly moved; or a person displaced by war or natural disaster. Demographers lack a single, operational definition for migration because it occurs under different conditions.
The causes of migration are related to the specific contexts in which they take place. First, the composition of migration streams are characterized by structural forces such as the global economy. Second, sociocultural differentials (gender, class, caste, etc.) have important implications for individual mobility.
Because migration occurs under different circumstances, the demographic implications for receiver populations change accordingly. For example, when large numbers of rural residents migrate to cities, infrastructure problems may arise in urban areas.
