Scribe Post: Factors affecting CBR/CDR
Monday in class we learned about factors that affect the Crude Birth Rate (CBR) and the Crude Death Rate (CDR). First, however, we viewed a poulation map of the world which is as follows. 
The larger the country the larger the total population. We then reviewed the equation for AGR, also called the Rate of Natural Increase, which is (CBR-CDR)/10.
The Factors which affect CBR/ Total Rate of Fertility (TRF)/ Replacement Fertility (RF)
1. As value of kids as labor increases the number of births also increase. The more reliant each parent is on the kids to work for them as labor the more likely it is they produce more offspring for greater efficency.
2. As cost of raising kids increase the number of births decrease.
3. As availability of legal abortion increases the number of births decrease.
4. As the availability of birth control increases the number of births decreases.
5. As infant mortality rate increases the number of births also increases.
6. As the availability of a Pension System increases the number of births decreases.
7. Availability of education/opportunities for women increases the number of births decrease.
8. As the average age of marriage increases the number of births decreases.
9. As urbanization increases the number of births decrease.
10. Religon/Tradition/Gov is the wild card, could increase or decrease the number of births
Factors affecting CDR
1. As medicines increase the number of deaths decrease.
2. As sanitation increases the number of deaths decrease.
3. As conflicts increase the number of deaths also increase (War, etc.)
These are the main 3 for CDR but their are others such as food, natural disastor, etc.
Sam, good first scribe post, but a couple of suggestions:
1. Any image you incorporate (glad you found the cartogram) needs to have the source referenced under it–ideally you would link to it.
2. As scribe, your role is to produce something more than just an outline of what went on the board. It is best for those absent if you explain why the relationships happen. For example, the Infant Mortality Rate one is a little tricky for some. Also, will someone who was not there know what we meant by “sanitation?”
Let me know if you need a hand.

Also, you should categorize the post with 3 things:
1. SamA
2. Scribe Post
3. Unit 6
You can find these categories to click off in the dashboard editor-then hit update to save the changes.
Sam-I have to finalize my grades. You never address any of these corrections so I’m adding the categories and giving this a bit more catchy title than “scribe post.”
