they indicate how many people are born verses how many die. more born than dead = population growth more dead than born= popultation decrease
The difference between the two is 'population growth' if it is a positive number or 'population decline' if it is negative.
RNI stands for Rate of Natural Increase, which is a demographic term used to measure the difference between birth rate and death rate in a population. It helps understand population growth dynamics in a specific region or country.
The death rate is a factor that affects population growth because it determines the rate at which individuals are leaving the population. A high death rate would result in a decrease in population growth, while a low death rate would lead to an increase in population growth. It is an important factor to consider in understanding population dynamics and demographic trends.
Indonesian birth rates may be attributed to the high quantity of rice comsumed by the populace, while German birth rates are affected by beer and spirit comsumption. Death rates in both areas are the result of totalitarian regimes, including nazism, buddhism, and chauvinism.
Some of the factors include: -Population Momentum -Affluence -Technology -Whether or not a country is Developing/Developed -Disease -Immigration and Emigration -Respect for Women ( countries that treat women as second-class citizens often have higher fertility rates) -Epideimiologic Transition -Birth Rate -Death 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.
Birth Rate - Death Rate = Alive people Alive people to Last years Alive people = rate
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).
Demographers figure out population growth by comparing birth rates and death rates.

death rate is subtracted from birth rate.
birth rate - death rate = growth rate
birth death migration/emigration
Birth rates and death rates
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.
Stage 1: High birth and death rates, leading to a stable population. Stage 2: High birth rates and decreasing death rates, resulting in rapid population growth. Stage 3: Declining birth and death rates, leading to a slowing population growth. Stage 4: Low birth and death rates, resulting in a stable or declining population.
