A demographic survey is a research tool used to collect data about the characteristics of a population. This survey typically gathers information on factors such as age, gender, ethnicity, income, education, and occupation. The data collected helps organizations understand the makeup of a community or target audience, which can inform decision-making and policy development. Demographic surveys can be conducted through various methods, including online questionnaires, phone interviews, or in-person surveys. The results are often analyzed to identify trends and patterns, which can be useful for businesses, governments, and researchers in areas like marketing, public health, and social services.
