In today's class we talked about visualizing population.  We watched a youtube video on Hans Rosling and he was trying to animate data.  We saw in the video that in 1810 almost every country died younger than forty and made less than $4,000 a year.  And now, if a country's life expectancy was under forty and you made less than $4,000 a year, you are considered poor and sick and above that is rich and healthy.  During the industrial revolution, the western countries went up in GDP per capita and life expectancy.  WWI and the Spanish flu epidemic killed millions and millions of people which affected the population and life expectancy.  By 2009, most country's went from the poor and sick category to the rich and healthy.  Tomorrow we are having a quiz on the video that we watched in class today.  I think I'll do pretty good on it because I understood the video and everything we were talking about today.
