1.) Ratio of girls to boys in primary and secondary (Schooling) - income per person.
Explanation - In video one the comparison is between the ratio of boy and girls going to primary and secondary schools, to income per person. This shows us with more children going to school and getting an education, the country as a whole drives to maturity and starts having high income jobs. In development this shows that the country is exiting the the grid stage of Rostow"s five step model. In countries that have had infrastructure are now shifting to tertiary jobs. We can follow the main countries that go through this quickest are the ones with heavy export in ability, had cheap labor, and a giant workforce. For example China would be perfect. Large workforce, cheap labor, and most importantly it has a major and easy to access port.

2.) Children per woman - co2 emissions (per person in tones)
Explanation - In video two, the two variables were, Children per woman (total fertility), and co2 emissions (per person in tones). Throughout the video the countries go on a very linear line. With exception of world war 2, most of the countries dropped in births, and with that the effect was more wealth because elf less economic burden. This lead to the ability to buy cars, access to planes, and ocean liners. The reason fertility goes down is that that children become economic burdens, and with the increase of jobs that require driving distances, they cannot afford to have gas bills, and feed the children.
