Which option gives the most accurate concept of population density?

Answer and explanation

Correct answer: Density = population ÷ area; it shows the average concentration of people

Correct answer: A — population density is population divided by area, usually expressed as people per square kilometre. First identify the two quantities: the number of people and the land area in which they live. Dividing the population by the area gives the average number of people occupying each unit of area. For example, 1,000 people living in 10 square kilometres gives a density of 100 people per square kilometre. Option B reverses the formula and does not measure birth rate; birth rate concerns births during a period. Option C uses weather elements and has no connection with demographic density. Option D combines social characteristics, not population and area. Remember: density asks ‘how many people in how much space?’ It is an average and may hide differences between crowded and sparsely settled localities.
