Screencast1: For Screencast 1 the 2 variables i used were life expectancy and GDP Per capita. Life expectancy is how long a new born baby is projected to live in it's given country. GDP Per capita is the average income in a country. The chart clearly shows that as GDP Per capita rises life expectancy rises. This is because when people are making more money they can afford things like sanitation,medicine,and health care so there not as likely to have epidemics like HIV/AIDS. Country's on the left side of the chart like Sierra Leone with low GDP Per capita have low life expectancy because they cannot afford the sanitation and medicines to combat epidemics. The chart slowly rises in the beginning. Then by 1900 things start to speed up. This could be due to medical advancements in the more developed countries. Less Developed countries are still lagging behind.After 1900 to 2012 it stays at the same pace of growth with the exception of some countries rapidly decreasing for a few years then bouncing back. This could be due to an outbreak of an epidemic or war.
Screencast 2: For Screencast 2 the variables i used were Children per woman ( total fertility) and ratio of boys to girls in primary and secondary education. Total fertility is the average amount of children a woman has in a given country. The ratio of boys to girls in education show the level of education girls are receiving in a given country. The chart shows that as the ratio of girls in education rises the number of children an average woman has falls. This is because when woman are receiving higher levels of education they get jobs and don't want to have kids until later on. Women receive higher education in more developed countries and in more developed countries children are an economic burden instead of an economic advantage. Less developed countries like Niger average 7.6 kids per woman. The chart shows more developed countries getting to a certain point then stalling and less developed countries catching up. This is due the more developed countries reaching a 50/50 ratio and then stalling and the less developed countries still trying to reach that mark.
