SEV5.b (MC) Population growth can be calculated by looking at the values of several variables. Which two variables in the calculation increase growth rate? birth and death rates birth and immigration rates death and emigration rates immigration and emigration rates

## Step 1<br />Population growth is determined by the balance between the number of births and deaths in a population. <br /><br />## Step 2<br />When 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.<br /><br />## Step 3<br />Immigration 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.<br /><br />## Step 4<br />Therefore, the two variables that increase the growth rate in the calculation of population growth are birth and immigration rates.
