Environmental Science Chapter 9 Lecture Notes The Human Population

Chapter 9 Targets 1. I can define demography and describe the 2 general categories of population growth they study. 2. I can describe how the size and growth rate of the human population has changed in the last 200 years. 3. I can make predictions about population trends based on age structure. 4. I can describe how survivorship, fertility, migration, death rate and life expectancy affect populations. 5. I can describe the four stages of the demographic transition. 6. I can name the 2 main factors affecting birth rates.
