If birth rates exceed death rates, the population increases proportionally. If death rates exceed birth rates, the population decreases.
death rate birth rate
Population growth is influenced by the balance of birth rates, death rates, immigration, and emigration. A high birth rate increases the population, while a high death rate reduces it; when birth rates exceed death rates, population growth occurs. Immigration adds to the population, while emigration decreases it. The overall effect on population growth depends on the interplay of these factors; for instance, a country with high birth rates and net immigration will likely experience significant population growth.

the birth rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
by birth control
If the birth rate is higher than the death rate, the population increases. If the death rate is higher than the birth rate, the population decreases.
Demographers figure out population growth by comparing birth rates and death rates.
The basic needs like food, shelter are some of the factors that affect the population's growth regardless of the size.

death rate is subtracted from birth rate.
Birth rate: The number of individuals being born into the population. Death rate: The number of individuals dying in the population. Immigration: The movement of individuals into the population. Emigration: The movement of individuals out of the population.
The r value in the exponential equation is the rate of natural increase expressed as a percentage (birth rate - death rate). So the math includes the birth rate and the death rate when implementing the equation. Students may have a hard time understanding that population growth is controlled not only by birth and death rates but also by the present population. The mathematics of exponential growth govern the prediction of population growth. Your welcome Ms. Musselma...'s class.
