How much did the population change between 1950 and 1960? What was the average annual change for that period? Hint: Calculate the changes, then calculate the mean, or average, by dividing by the number of years. State the units clearly. The units are listed on the chart.

World population increased by 22% in 1960-1970, compared to 20% in 1950-1960, which was twice as much as the 20% registered for the 20 years 1930-1950.

Step-by-step explanation:

0.484 billion       0.0484 billion per year

Step-by-step explanation:

Population change between 1950 and 1960 = 3.039 - 2.555 = 0.484 (billion)

Number of years between 1950 and 1960 = 1960 - 1950 = 10 years

Average population change per year = 0.484 ÷ 10 = 0.0484 billion per year
