What impact does increased immigration have on population size?

Increased immigration results in a net gain of individuals in a population, directly contributing to its growth. When individuals migrate into a country, they add to the overall demographic, which can lead to a larger population size. This influx of people can influence various factors, such as the economy, workforce, and cultural diversity within the area.

Immigration often compensates for low birth rates in certain regions, making it a significant factor in population dynamics. Additionally, depending on migration policies and the circumstances of the immigrants (e.g., seeking better job opportunities, fleeing conflict), populations can experience both growth and shifts in demographics.

Other factors like emigration or natural population decrease may counteract some of this growth, but generally, increased immigration leads to an overall increase in population size.
