This video builds on a basic review of human population dynamics and exponential growth rate. Working from the definitions of total fertility rate, replacement fertility rate, we analyze age structure diagrams and practice making inferences about TFR and population growth based on the age structure diagrams. Applying skills to draw conclusions from age structure diagrams about a populations potential environmental impacts are and their stage of economic development. We also spent some time identifying solutions that can help a country reduce their TFR and slow population growth.
