Life Stages and Demographics: Understanding Human Growth and Population Patterns
Life stages and demographics play a crucial role in understanding human development, health needs, social behavior, and population trends. From infancy to old age, every stage of life has unique physical, emotional, and social characteristics. Demographics help analyze population structure based on age, gender, income, education, and location. Together, life stages and demographics guide planning in healthcare, education, policy-making, and economic development.
What Are Life Stages?
Life stages refer to the distinct phases of human growth and development from birth to death. Each stage is marked by specific biological, psychological, and social changes.
