Demographic analysis is the study of populations, focusing on characteristics such as age, gender, income, education, and ethnicity. This analysis helps researchers and policymakers understand the composition and trends within a population, which can inform decisions in areas like public health, urban planning, and marketing. By examining demographic data, organizations can identify target audiences and assess community needs. For example, census data provides valuable insights into population changes over time, allowing for better resource allocation and strategic planning. Overall, demographic analysis is essential for understanding societal dynamics and guiding effective interventions.
