## Step 1Population growth is determined by the balance between the number of births and deaths in a population. ## Step 2When the birth rate is higher than the death rate, the population grows. Conversely, when the death rate is higher than the birth rate, the population decreases.## Step 3Immigration and emigration also play a role in population growth. Immigration refers to the movement of individuals into a population from another location, which increases the population size. Emigration refers to the movement of individuals out of a population to another location, which decreases the population size.## Step 4Therefore, the two variables that increase the growth rate in the calculation of population growth are birth and immigration rates.
