Ugh, the fact that many of these charts show raw # of deaths versus deaths/100k really masks how much things have improved. In 1968, the population was 64% of our current population... So a flat line is actually a pretty massive improvement.
I.e., the graph in slide #10 says:
Cancer in 1990 killed 40422, but in 2010, 50962.
Heart disease in 1990 killed 36545, but in 2010, 45783.
That seems like cancer and heart disease have become worse, not less deadly over the years. That slide is baffling unless you realize that the population must have increased significantly between 1990 and 2010.
Graphs like this are misleading and it's often difficult to collect all the raw data to do the datacube aggregations across multiple dimensions to visualize the data and understand these sorts of details.
