What type of growth does (P₂ − P₁) show in population growth calculation?

Answer and explanation

Correct answer: Absolute growth

Direct answer: Option C is correct. In this notation, P₁ means the population at the earlier time and P₂ means the population at the later time. Subtracting P₁ from P₂ gives the actual numerical change in the number of people: absolute growth = P₂ − P₁. For example, if a town increases from 10,000 to 12,000 people, its absolute growth is 2,000 people. Option A is wrong because an annual percentage rate requires comparison with the base population and a time period, usually expressed as a percentage. Option B is wrong because natural increase is births minus deaths and does not by itself include migration. Option D is wrong because density is population divided by area. Memory cue: subtraction gives the number added; division by the base and multiplication by 100 gives a percentage.
