A country has a population of 30 million. Natural increase is 1.4 percent and net migration is negative 0.4 percent. What is the approximate total increase in one year?

Answer and explanation

Correct answer: 300,000

Correct answer: B, 300,000 people, or 3 lakh. First find the total growth rate by combining natural increase and net migration: 1.4 percent + (−0.4 percent) = 1.0 percent. Now calculate 1 percent of 30 million: 30,000,000 × 0.01 = 300,000. Thus, the population increases by approximately 3 lakh in one year. A is too small and does not equal 1 percent of 30 million. C, 420,000, is the natural increase alone: 1.4 percent of 30 million, so it ignores the population loss through migration. D is too large and applies an incorrect rate. The negative migration rate reduces, but does not completely cancel, the positive natural increase. Memory cue: combine signed rates first, then multiply the resulting rate by the population.
