A region's population declines from 300000 to 270000. What is the absolute population change?

Answer and explanation

Correct answer: Decrease of 30,000

Answer: B, a decrease of 30,000. To find population change, subtract the initial population from the final population: 270,000 − 300,000 = −30,000. The negative result shows that the population became smaller. Therefore, the absolute size of the change is 30,000, and its direction is a decrease. Option A has the correct numerical difference but gives the opposite direction. Option C is incorrect because the difference between 300,000 and 270,000 is 30,000, not 3,000. Option D states the final population itself and incorrectly describes it as an increase. A helpful method is: subtract first, then interpret the sign; a negative sign means decline.
