Question

what is population growth rate?how it is calculate?also maintain the term derived from it.​

Answer 1

Population growth is the increase in the number of individuals in a population. Global human population growth amounts to around 83 million annually,or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billionin 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100.However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100.

Answer 2

Answer:

The "population growth rate" is the rate at which the number of individuals in a population increases in a given time period, expressed as a fraction of the initial population.

Population growth rate is the percentage change in the size of the population in a year. It is calculated by dividing the number of people added to a population in a year (Natural Increase + Net In-Migration) by the population size at the start of the year.
