gravity model of migration

The gravity model of migration suggests that people are more likely to move from one place to another based on the size of the locations involved and the distance between them. Larger cities attract more migrants because they offer better job opportunities and amenities. Conversely, the further away two places are, the less likely someone is to move between them. Essentially, just like gravity pulls objects together, factors like population size and proximity influence human migration patterns, creating a kind of social "pull" or "push" effect.
