Question

Calculate a population that has a birth rate of 10/1000, a death rate of 9/1000, an immigration rate of 3/1000 and an emigration rate of 7/1000.

What is the populations growth rate?

Answer 1

The population's growth rate is calculated using the formula involving birth rate, death rate, immigration rate, and emigration rate. In this case, it results in a negative growth rate of -0.3%, indicating a declining population.

Step-by-step explanation:

To calculate the population growth rate, we use the formula: growth rate = birth rate – death rate + immigration rate – emigration rate. Given that the birth rate is 10/1000, the death rate is 9/1000, the immigration rate is 3/1000, and the emigration rate is 7/1000, we can plug these values into the formula:

Growth rate = (10/1000) - (9/1000) + (3/1000) - (7/1000)

Growth rate = (1/1000) - (4/1000)

Growth rate = -3/1000

This means that the population is shrinking at a rate of 3 people per 1000 individuals each year. To convert this to a percentage, we simply multiply by 100:

Population growth rate = -3/1000 * 100

Population growth rate = -0.3%

Therefore, the population's growth rate is -0.3% indicating a decline in the population size.
