Demographic Research
The systematic study of human populations, their characteristics, and changes over time using statistical and analytical methods.
Overview
Demographic research is a foundational field within social science that examines the size, structure, distribution, and dynamics of human populations. This discipline combines rigorous statistical analysis with social theory to understand how populations change and evolve over time.
Core Components
Demographic research focuses on several key population characteristics:
- Birth rates and fertility patterns
- Mortality and life expectancy
- Migration flows and patterns
- Age and gender distribution
- Population density and spatial distribution
- Household composition
- Socioeconomic status indicators
Methodologies
