#AP Human Geography: Population Distribution - The Night Before Review 🌃

Hey there! Let's get you prepped and feeling confident for your AP Human Geography exam. We're going to break down population distribution and its impacts using a clear, engaging approach. Time to make those connections and nail this exam! 💪

#🌍 Population Distribution: Key Factors

Population distribution isn't random; it's shaped by a mix of factors. Let's look at how where people live (urban vs. rural), their age (dependency ratios), and a country's stage in the Demographic Transition Model (DTM) all play a role.

#🏙️ Urban vs. Rural

• Rural Areas: Often tied to agriculture, these areas can be densely populated in some regions, especially in developing countries. Think about the agricultural heartlands of Asia.

• Urban Areas: Centers of industry, commerce, and services. Urbanization is happening rapidly across the globe, leading to booming cities and infrastructure challenges.

#👵 Age Structure

• Dependency Ratio: This is the ratio of non-working people (kids and retirees) to working-age adults. A high dependency ratio can strain a country's resources.

  • Younger Population: Requires investment in education, childcare, and job creation.
  • Graying Population: Needs more healthcare, retirement support, and social security.

#📈 Demographic Transition Model (DTM)

• Stage 2 (High Growth): Rapid population growth, like in parts of Sub-Saharan Africa, often with high Total Fertility Rates (TFRs).

• Stage 5 (Decline): Population decline, like in Japan, which requires pro-natalist policies to encourage more births.
