Human Geography and Population

Population Dynamics and Demography​

1. Population Measures​

Key Demographic Indicators:

  • Population density: People per area (km²)
  • Birth rate: Births per 1,000 population per year
  • Death rate: Deaths per 1,000 population per year
  • Natural increase: Birth rate - death rate (%)
  • Life expectancy: Average lifespan
  • Fertility rate: Average children per woman

Population Growth:

  • Exponential growth: Doubling time (currently ~60 years)
  • Linear growth: Constant increase
  • Logistic growth: Slowing as carrying capacity approached
  • Growth rates: Vary by development level
  • Future projections: Complex models

2. Demographic Transition Model (DTM)​

Stage 1: High Stationary

  • High birth and death rates
  • Low population growth
  • Pre-industrial societies
  • High infant mortality

Stage 2: Early Expanding

  • Falling death rates (improved healthcare/sanitation)
  • High birth rates remain
  • Rapid population growth
  • Early developing countries

Stage 3: Late Expanding

  • Falling birth rates (education, contraception, development)
  • Low death rates
  • Slowing growth
  • Mid-stage developing countries

Stage 4: Low Stationary

  • Low birth and death rates
  • Minimal growth
  • Developed countries
  • Aging populations

Stage 5: Declining (Proposed)

  • Death rates exceed birth rates
  • Population decline
  • Some developed countries (Japan, Europe)
  • Immigration may offset

3. Age Structure and Population Pyramids​

Age Structure Analysis:

  • Young population: High proportion of children (developing countries)
  • Mature population: More even distribution (transition states)
  • Aging population: High proportion of elderly (developed countries)

Population Pyramids:

  • Bar graphs showing age structure
