Question

In 1950, the population of a small suburb in los angeles, california, was 20,000. the birth rate was measured at 25 per 1000 population per year, while the death rate was measured at 7 per 1000 population per year. immigration was measured at 600 per year while emigration was measured at 200 per year. calculate the population size in 1951.

Answer 1

Total Population = Current Population + (Population * Birthrate) - (Population *Deathrate) + Immigration rate - emigration rate

Total Population = 20000 + 20000(25/1000) - 20000(7/1000) + 600 - 200

Total Population = 20400 + 500 - 140

Total Population = 20760
