If birth rates exceed death rates, the population increases proportionally. If death rates exceed birth rates, the population decreases.
because if there's alot of people having babies more than death the population will go up or increase. If there's more deaths then reproduction then the population will go down or decrease.
When people are born, population rises. When more people are born, population rises more quickly.
It affects the population because when people die the Death Rate goes up, and when people are born the birthrate goes up.
death rate birth rate
One factor that does not directly affect population growth is the color of the sky. Population growth is typically influenced by factors such as birth rates, death rates, immigration, and emigration.
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
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.
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.
death rate is subtracted from birth rate.
birth rate
birth rate - death rate = growth rate
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.
The model of population growth that states the growth rate remains constant because birth and death rates are equal is called zero population growth or ZPG. In this scenario, the population size does not increase or decrease over time due to the balance between births and deaths.
