An ecologist in Costa Rica wanted to determine the PGR for the country in 2018, and collected all of the data necessary to calculate the rate. She concluded that there were 34,560 births and 2,310 deaths within their population of 100,000. There were also 478 immigrants and 126 emigrants that year. What was the population growth rate for Costa Rica?

Respuesta :

The population growht rate is 32.602 % per year. Population growth can be calculated as = (births + immigrants) - (deaths + emigrants).

In this case, population growth is equal to = (34,560 births + 478 immigrants) - (2,310 deaths + 126 emigrants) = 32,602 new individuals per year

Total (original) population: 100,000 _____ 100%

                                             32,602  _____ X

In consequence, the population growth rate per year can be estimated by the following equation:

X = (32,602 x 100)/ 100,000 = 32.602 %
