TestHub · Accepted Answer

Population density is influenced by four basic processes.

Natality (Birth rate) and Immigration contribute to an increase in population density.

Mortality (Death rate) and Emigration contribute to a decrease in population density.

Therefore, an increase in immigration (A) and an increased birth rate (B) will lead to an increase in the density of the population.
