Introduction✨

  • The DTM showcases the changes in population structure over time.
  • Picture this as a journey: from an LEDC (Less Economically Developed Country) with high birth and death rates, transitioning to an MEDC (More Economically Developed Country) with lower birth and death rates.

Key stages🌱

  • LEDC: High birth & death rates.
    • Real-world example: Think of many countries in sub-Saharan Africa where both birth and death rates are high because of limited access to healthcare and education.
  • Transition: Death rates drop first, then birth rates.
    • Why?
      • Better food availability 🍲
      • Access to clean water 🥤 and sanitation 🚽
      • Sturdier housing 🏡
      • Example: Picture the early Industrial Revolution in England. More food, better living conditions, but people still had many kids because they could help out on farms.
  • Urbanization kicks in: Decreasing birth rates.
    • What's happening?
      • More city living 🏙️ (less farming)
      • Women's roles changing 👩‍💼
      • Healthcare improvements 🏥
      • Example: Modern-day China. Cities expanding rapidly, and with the One-Child Policy in place, the birth rate dropped.
  • Modernizing: Low birth & death rates.
    • Signs:
      • Higher living standards 🛍️
      • Cost of raising kids goes up 🍼💸
      • Female education rises 🎓, more women work 💼, leading to lower fertility.
      • Example: Think of countries like Japan or Germany where the cost of living is high, women are more educated, and birth rates are low.
  • Elder Boom: High elderly population.
    • Result: Increase in death rate, decrease in birth rate because, well, it's an older crowd!
    • Example: Present-day Italy or Spain, with a lot of grandparents but fewer youngsters.
