A district has a population of 800,000 and an area of 160 square kilometres. What is its population density?
Answer and explanation
Correct answer: C. 5,000 people per sq km
- Step 1: Density = population / area. Step 2. 800,000 / 160 = 5,000 people per square kilometre. Answer: 5,000 people per sq km. Why not the others: 799,840 people per sq km: That subtracts the area from the population. 50,000 people per sq km: That is ten times the correct density. 128,000 people per sq km: That multiplies instead of dividing.
