How does immigration impact population growth?

Immigration directly contributes to population growth by increasing the total population size. When individuals move to a new country, they add to the existing demographic, resulting in a larger population. This influx of people can be from various backgrounds, bringing different skills, cultures, and needs. As immigrants settle, they can also contribute to the birth rate if they have children in their new country, further enhancing population growth over time.

While there may be some relationship between immigration and factors like job availability or economic stability, the primary and most straightforward effect of immigration is the increase in the total number of people living in a country. This effect can lead to greater diversity and economic dynamism, but it is the sheer addition of individuals that is most relevant to the concept of population growth.
