How do you calculate the per capita growth rate r of a population?

Net reproductive rate (r) is calculated as: r = (births-deaths)/population size or to get in percentage terms, just multiply by 100. the population is so much bigger, many more individuals are added. If a population grows by a constant percentage per year, this eventually adds up to what we call exponential growth.

How is the per capita rate of increase for a population represented?

Per capita rate of increase (r) r = (birth rate + immigration rate) – (death rate and emigration rate). If r is positive (> zero), the population is increasing in size; this means that the birth and immigration rates are greater than death and emigration.

What is maximum per capita growth rate?

The maximum per capita growth rate for a population is called the intrinsic rate of increase. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).

What is per capita GDP growth?

Per capita gross domestic product (GDP) measures a country’s economic output per person and is calculated by dividing the GDP of a country by its population. Small, rich countries and more developed industrial countries tend to have the highest per capita GDP.

  2. Determine how many people are in the population that you want to measure.
  3. Divide the measurement by the total number of people in the population.
  4. For smaller measurements, multiply the total by 100,000.
