This concept in human geography describes the presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away. Instead of migrating to a location initially intended, an individual or group might find a more suitable option closer to their point of origin. For instance, someone planning to move from a rural area to a major city for employment might discover a comparable job in a smaller, nearby town, leading them to settle there instead.
The existence of closer, more accessible alternatives significantly alters migration patterns and economic activity. It reduces the flow of people and resources to distant locations by providing viable options within a shorter range, thereby impacting the growth and development of both the origin and destination areas. This concept has been a part of geographical understanding for decades, helping explain why predicted migration patterns often deviate from initial expectations.
