Why can density data not be considered a complete measure of social development?

Correct answer: Because it tells population per area but not income education and health quality directly

The direct answer is A: density gives population per area but does not directly give the quality of income, education or health. Density is a spatial indicator. It can show where people are concentrated and may suggest pressure on land or services, but it cannot by itself tell whether people are wealthy, educated, healthy or well served. Option A is correct because it states this limitation clearly. Option B is not a reason for incompleteness; including area is exactly what makes density a density measure. Option C is a benefit, not a limitation: density helps comparison. Option D is also a possible use, not a reason to reject it as complete. To judge development, combine density with income, schooling, health, employment, housing and service data. Exam cue: an indicator is not the whole condition.
