they indicate how many people are born verses how many die. more born than dead = population growth more dead than born= popultation decrease

How does the birth rate compare to the death rate of a population whose size remains constant?
The difference between the two is 'population growth' if it is a positive number or 'population decline' if it is negative.
What is a llamas life cycle?
Birth, growth into the adulthood, mating and giving birth to crias, and death.
Why death rate is a factor that affecting the population growth?
The higher the death rate is, the fewer people there are on the Earth.
Is human population size controlled by natural forces?
Yes,the natural calamities kills many people n the population decrease. It proves that god care for us so he kills people n control population growth. But it is in a small extent. There is more number of birth than death
What is a list of the three stages of labor in proper order?
Birth, growth, and death
Relationship between birth rate death rate and growth rate?
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.
How are birth rate and death rate used to measure population growth?
Birth Rate - Death Rate = Alive people Alive people to Last years Alive people = rate
Population growth rate definition?
Population growth rate is the rate at which populations change in size over time as a fraction of the initial population. The formula used to measure growth rate is (birth rate + immigration) - (death rate + emigration).
How do demographers figure out population growth.?
Demographers figure out population growth by comparing birth rates and death rates.
When calculating global population growth the death rate is?
death rate is subtracted from birth rate.
Calculate the growth rate of a population. (class notes)?
birth rate - death rate = growth rate
How are birth and death rates accounted for in the exponential population growth equation?
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.
What do demographers compare to figure out population growth?
Birth rates and death rates
What are the four processes that determine population growth?
The four processes that determine population growth are birth rate, death rate, immigration, and emigration. Birth rate and immigration increase population size, while death rate and emigration decrease population size. These processes collectively determine whether a population grows, shrinks, or remains stable over time.
What is three causes that cause population growth?
birth death migration/emigration
What are the main components of population growth?
The main components of population growth are birth rate, death rate, immigration rate, and emigration rate. Birth rate refers to the number of births in a population, while death rate reflects the number of deaths. Immigration rate is the influx of individuals from another population, while emigration rate is the outflow of individuals from a population. These components together determine the overall growth or decline of a population.
What is the model of population growth that states the growth rate remains constant because birth and death rates are equal?
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.
