ProfessorIn Demographics, the rate of natural increase (RNI) is the crude Birth Rate minus the crude death rate of a population. If we neglect the migration, then a positive RNI number means that the population increases and a negative number means that the population decreases.
When looking at countries, it gives an idea of what position in the Demographic Transition Model, but to find out how much a country is growing, the population growth rate should be observed.
Usually developing countries have a positive or high natural increase rate Developed countries have a negative/neutral or low natural increase rate [1], but many developed countries have their population increasing due to Immigration despite their negative RNI.
The formula for the rate of natural increase is:
(Crude birth rate − Crude death rate) / 10, where birth and death rates are in per mil. The result is the rate of natural increase in percentage form.
For example, Paraguay's crude birth rate (28.47) - the crude death rate (4.49) is 23.98; divide that by 10 and the result is 2.39%, Paraguay's rate of natural increase.
To calculate the natural increase of a population, you take the the countries' birth rate (number of live births per 1000 population per year) minus the countries' Death Rate (number of deaths per 1000 population per year)

No.
What does Population change mean in geography terms?
Population change refers to the increase or decrease in the number of people living in a specific area over a period of time. It is typically measured through data on births, deaths, and migration patterns. Understanding population change is crucial for assessing the social, economic, and environmental impacts on a region.
Is genetic change desirable or not?
Genetic change is desirable in order to have an abundance of diversity within a population. This makes the population less susceptible to disease and illness, making the population more resilient.
What is the difference between population growth and population change?
Population growth refers to an increase in the size of a population over time due to natural births, while population change encompasses all factors that contribute to alterations in the population size, including births, deaths, immigration, and emigration. Population growth specifically focuses on the numerical increase, whereas population change considers both increases and decreases and can be either positive or negative.
