An area's population changed from 8,000 to 7,600. What is the most correct explanation?

Answer and explanation

Correct answer: Absolute growth is negative 400

Direct answer: B, absolute growth is negative 400. Absolute change is found by subtracting the initial population from the final population: 7,600 − 8,000 = −400. The minus sign shows that the population decreased, so the population fell by 400 people. A is wrong because +400 would describe an increase; 400 is only the size of the decrease. C is wrong because the percentage change is (−400 ÷ 8,000) × 100 = −5%, not 100%. D is wrong because a stable population would remain at 8,000, whereas this population became 7,600. The same method works in every similar question: final value minus initial value. Memory cue: final minus initial; a smaller final number produces a negative change.
