A source of market data that compiles population statistics with regard to distribution of population by region, etc

• A. Census of population
• B. Population survey
• C. Market analysis
• D. Demographic report

Answer: (A)

A census is the official, comprehensive count of a population conducted by the government at regular intervals, which records where people live and other demographic details. Because it aims to include every person and every region, it provides the precise distribution of population by region, making it the most suitable source for that information.

A population survey, by contrast, samples a portion of the population to estimate characteristics, so it doesn’t give exact regional distribution for the entire population. A market analysis focuses on business opportunities and demand rather than counting people across regions. A demographic report may summarize census findings or use census data, but the primary source for geographic population distribution is the census itself.
