->> 
+>> - The development of agriculture     
+>> - The transition from rural to urban residence    
+>> - An increased awareness of disease prevention and cures     
+>> - Change in the societal role of females     
+>> - Changes in preferred family size     
+
+>> ### Stages
+
+>> 1. **Pre-Transition**
+>>    - Both birth and death rates are ```high```
+>>       - Woman have ```6 to 10``` children on average
+>>       - Most children die before adulthood
+>>    - The population does not grow/grows ```minimally```
+>>    - **```No country is currently in this stage```**
+>>    - Food is ```hunted``` and ```gathered```
+>>    - Very ```basic forms``` of agriculture
+>>    - Life is ```harsh and uncertain```
+>>    - ```Diseases are very common and deadly```
+>>    - Most people die from ```disease```, ```poor nutrition```, or ```contaminated drinking water```
+
+>> 2. **Early Transition**
+>>    - Birth rates are ```high```, death rate drops ```dramatically```
+>>    - ```Population explosion```
+>>    - ```Very few countries``` are in this stage
+>>        - Examples: ```Chad, Niger```
+>>    - ```Agriculture``` is very common
+>>    - Commercial food production ```increases```
+>>    - ```Less diseases``` due to simple sanitation improvements
+>>    - People begin ```migrating``` to ```urban``` areas
+>>    - Large families persist, but less children die
+
+>> 3. **Late Transition**
+>>    - Birth rate ```drops quickly```, death rate drops further
+>>    - ```Small families``` are becoming the norm
+>>    - The ```natural increase``` rate (in population) drops
+>>    - Most people live in ```urban``` areas
+>>    - ```Mechanization```, especially in ```agriculture```
+
+>> 4. **Post Transition**
+>>    - Birth rate and death rate ```stabilize``` to around the same level
+>>      - However the ```replacement rate``` (number of births per woman that result in a stable population, is usually ```2:1```) is ```dramtically declining```
+>>      - Alot of the population is ```graying```
+>>    - More than ```80%``` of the population is urban
+>>    - Woman work ```full-time``` jobs similarly to men
+
+> ## Push and Pull Factors
+
+>> **```Push Factor```**: A reason that encourages people to move away from their current country
+>>   - Examples: ```Undesired climate, threat of war, economic problems, poor environmental conditions```
+
+>> **```Pull Factor```**: A reason that makes particular country seem attractive to potential immigrants
+>>   - Examples: ```Economic opportunities, political stability, freedom, residental friends and family```
