A population of 2000 has 160 births, 100 deaths, 40 immigrants and 20 emigrants in a year. What is the population growth rate?
Answer and explanation
Correct answer: B. 4.0%
- Step 1: Net change = births - deaths + immigrants - emigrants. Step 2. 160 - 100 + 40 - 20 = 80; 80/2000 = 0.04. Answer: 4.0%. Why not the others: Migration must be included.
