Explanation:

Birth rate refers to the number of births in a population. More births mean more individuals added to the population. Immigration is the movement of individuals into a population. So, both birth rate and immigration add individuals to a population, causing it to increase. Emigration (individuals leaving) and death rate (individuals dying) reduce the population size.

birth rate and immigration
