Consequences of Population Growth AP Human Geography Quiz

📚 Quick Study Guide

• 📈 Crude Birth Rate (CBR): 👶 The number of live births per 1,000 people in a year.
• 📉 Crude Death Rate (CDR): 💀 The number of deaths per 1,000 people in a year.
• ➕ Natural Increase Rate (NIR): 🌿 CBR - CDR (expressed as a percentage). It excludes migration.
• 🌱 Doubling Time: ⏳ The number of years needed to double a population, assuming a constant rate of natural increase. Approximate using the Rule of 70: $Doubling \, Time = \frac{70}{Growth \, Rate}$.
• 🌍 Total Fertility Rate (TFR): 👩‍👩‍👧‍👦 The average number of children a woman will have during her childbearing years (ages 15-49).
• 👵 Dependency Ratio: 🤝 The number of people who are too young or too old to work, compared to the number of people in their productive years. Can strain social security and healthcare systems.
• 🗺️ Demographic Transition Model (DTM): 📊 A model that shows how population changes over time as a country develops. Includes stages of high birth/death rates to low birth/death rates.
