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.
- Why?
- 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.
- What's happening?
- 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.
- Signs:
- 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.
