Question

Demography is the study of factors that affect \(\underline{\hspace{2cm}}\) and \(\underline{\hspace{2cm}}\) patterns. 
 

• A. Population density, dispersion
• B. Population size, dispersion
• C. Population density, distribution
• D. Population size, distribution

Hint:

Think of a national census. What are the two main things it measures? First, "how many people live in the country?" (population size), and second, "where do they live?" (population distribution). This is the essence of demography.

Answer 1

The Correct Option is D

Step 1: Core Concept:
The question identifies the two main areas of study within demography, which is the statistical analysis of populations.

Step 2: Breakdown:
Demography, in both human sociology and population ecology, investigates population characteristics and their changes. The primary focuses are:
\[\begin{array}{rl} \bullet & \text{Population size: The total number of individuals, influenced by births, deaths, immigration, and emigration. } \\ \bullet & \text{Population distribution: The spatial arrangement of individuals within a geographic area. } \\ \end{array}\]Although population density (size per area) and dispersion (spacing of individuals) are crucial demographic measures, they stem from population size and distribution. Therefore, the most encompassing definition of demography is the study of factors influencing population size and distribution patterns.

Step 3: Conclusion:
Demography studies the factors that affect population size and distribution.
