A Correct answer
Explanation

Percentage change = ((New - Old) / Old) * 100. Change = 735000 - 906000 = -171000. Percentage = (-171000 / 906000) * 100 = -18.87%. This is approximately a 19-20% decrease.

AI explanation

The change in population is 906,000 minus 735,000, resulting in a decrease of 171,000. To find the percentage change, divide the decrease by the original 1975 population: (171,000 / 906,000) multiplied by 100. This calculates to approximately 18.8 percent, which rounds to a 20% decrease. The result is 20% decrease.
