Demographics refers to the statistical study of populations, particularly human populations. It encompasses the quantitative analysis of populations by examining attributes such as age, sex, race, ethnicity, income, education level, occupation, and geographic location. Demographers use this data to understand population trends, patterns, and structures. This information is crucial for various fields, including sociology, economics, public health, urban planning, and marketing.

Key demographic indicators include birth rates, death rates, migration patterns, and population growth or decline. Analyzing these indicators helps in forecasting future population sizes and compositions. For instance, understanding an aging population helps governments plan for healthcare and retirement systems, while knowledge of a growing young population can inform educational and employment policies.

Demographic data is typically collected through censuses, surveys, and vital registration systems. These methods provide a snapshot of a population at a specific time and allow for tracking changes over time. The interpretation of demographic data requires careful consideration of social, economic, and cultural contexts. It is a dynamic field, constantly evolving to capture new aspects of human populations and their interactions with the environment and society.
