Population projections are estimates about how many people will live in a specific area in the future. These estimates are based on current data, such as birth rates, death rates, and migration patterns. For example, a city might project that its population will grow by 20% over the next decade due to an influx of new residents and higher birth rates. These projections help governments and organizations plan for the future. They can influence decisions about infrastructure, schools, and healthcare services. By understanding potential population changes, communities can better prepare for the needs of their residents and ensure resources are available when needed.
