Study Guide Overview
This study guide covers population aging with a focus on the Demographic Transition Model (DTM), specifically stages 4 & 5. It explains population pyramids and their interpretation. The guide details the political, social, and economic consequences of aging populations. Finally, it connects these impacts to the DTM and emphasizes the interconnectedness of the consequences.

#1. Demographic Transition Model (DTM) & Population Pyramids
#Understanding the Basics
- The Demographic Transition Model (DTM) helps us understand how populations change over time. It's key to grasping why some countries have aging populations. 👴👵
- Stages 4 & 5 of the DTM are where things get interesting for aging populations.
- Low birth rates: More women are educated and in the workforce, leading to fewer children.
- High death rates: Sounds counterintuitive, but it's due to a large elderly population. People are living longer, but eventually, they do pass away, which increases the crude death rate.
- Negative Natural Increase Rate (NIR): In Stage 5, deaths can outnumber births, leading to population decline.
