Demographic Transition Model
NO MODEL IS REAL BUT THEY GIVE A US A GOOD FRAME TO WORK WITH. KNOW THIS MODEL. LOVE THIS MODEL.
In stage 1 most people are subsistence farmers. One can grow old (assuming high child mortality rates). US in 1700s and early 1800s would be a good example. Most people would be farmers. No country is in stage 1 currently.
In stage 2 happens in great part to clean waters and sewers. Clean water is very important. Some technology emerges - can be very simple. Birth rate is still high because children are still an asset as workers and retirement system. Late stage 2 or early 3 we see a huge drop in death rates. Families have high rates of children.
Stage 3 - Start of the Industrial Revolution and urbanization becomes common by the later part, perhaps commercial agriculture (2nd Agriculture Revolution). Children are not as big of an asset. They are mouths to feed. Stage 2 to 3 will see the highest population increase and heavy, heavy immigration for jobs.
Stage 4 - Population growth is slow. Women typically have more equality. This is a developed nation. The US is likely a 4. If there was no longer immigration entering the country, we might be a Stage 5.
Stage 5 would be countries like Japan, Spain, and perhaps Italy.
