Residency Index

The Residency Index is a measure used to assess the proportion of people living in a specific area who are originally from that area. It compares the number of residents to the number of those who have moved in from elsewhere. A high Residency Index indicates a stable population with many long-term residents, while a low index suggests a more transient or diverse population with many newcomers. This metric can help understand community dynamics, local identity, and social cohesion in a given region.
