📚 Topic Summary
The Demographic Transition Model (DTM) is a model that describes population change over time. It's based on observed patterns in developed countries and relates birth rates and death rates to stages of economic development. As countries move through these stages, their population growth rates change. Understanding the DTM helps us analyze population pyramids and predict future population trends. Remember, it's a model, so it doesn't perfectly apply to every country, but it's a useful framework!

📝 Part B: Fill in the Blanks
Complete the paragraph with the correct words:
In Stage 1 of the DTM, both birth rates and death rates are ________, resulting in a relatively _______ population growth. Stage 2 sees death rates _________ due to improvements in _________ and sanitation, while birth rates remain high, leading to a rapid population _________. In Stage 3, birth rates begin to _________ as societies become more _________ and women enter the workforce. Stage 4 is characterized by low birth rates and low death rates, resulting in _________ population growth or even decline. Some argue a Stage 5 exists where birth rates fall _______ death rates.
Possible Answers: high, low, falling, healthcare, growth, decline, urbanized, zero, below.
🌍 Part C: Critical Thinking
How might the DTM need to be modified or adapted to account for the experiences of countries in Sub-Saharan Africa, considering factors like HIV/AIDS, political instability, and differing cultural norms?
