Internal migration refers to the movement of people within a country, often from one region or city to another. This can happen for various reasons, such as seeking better job opportunities, accessing education, or escaping unfavorable living conditions. For example, many individuals move from rural areas to urban centers like New York City or Los Angeles in search of work and a higher quality of life. This type of migration can significantly impact both the areas people leave and the places they move to. Regions experiencing an influx of residents may see economic growth and cultural diversity, while those losing population might face challenges like declining services and reduced economic activity. Understanding internal migration helps policymakers address these changes effectively.
