Explain Meaning of Demography.

Demography is the scientific study of human populations, focusing on their size, distribution, composition, and dynamics over time. It examines various demographic phenomena, including birth rates, death rates, migration patterns, age structure, fertility, mortality, and population growth.

The study of demography encompasses a range of quantitative methods, statistical techniques, and analytical tools to analyze population data, trends, and patterns. Demographers use census data, surveys, vital registration systems, and other sources of demographic information to study population dynamics and understand the factors driving changes in population size and structure.

Demography provides insights into the social, economic, environmental, and health implications of population trends, informing policymaking, planning, and decision-making in various fields such as public health, social welfare, urban planning, education, and labor markets. It helps policymakers, researchers, and practitioners to anticipate demographic challenges, plan for future needs, and design interventions to address population-related issues such as aging, urbanization, migration, inequality, and sustainability.

Overall, demography plays a crucial role in understanding the complexities of human populations, their interactions with the environment, and their impact on societies and economies, contributing to informed decision-making and evidence-based policies for sustainable development and well-being.
