Population Growth in Oktyabrsky District

According to the information provided, in 2010, the population of Oktyabrsky District was 50,000 people. The population increased by 2% in 2011 compared to the previous year, and by 5% in 2015 compared to 2011. We can calculate the population in 2015 by applying these growth rates to the initial population of 50,000.

To calculate the population in 2011, we can use the formula:

Population in 2011 = Population in 2010 + (Population in 2010 * Growth Rate in 2011)

Substituting the values, we get:

Population in 2011 = 50,000 + (50,000 * 0.02) = 50,000 + 1,000 = 51,000

Now, to calculate the population in 2015, we can use the same formula:

Population in 2015 = Population in 2011 + (Population in 2011 * Growth Rate in 2015)

Substituting the values, we get:

Population in 2015 = 51,000 + (51,000 * 0.05) = 51,000 + 2,550 = 53,550

Therefore, the population of Oktyabrsky District in 2015 was approximately 53,550 people.
