profound and simple!
A very interesting visual. A quick question, why is there so much variation in the data pre-1944? Was there a methodology change in the data collection? Or was there a systematic lifestyle change?
I'd believe either, but am leaning towards a difference in data collection. The biggest variation is due to the influenza outbreak, so it's possible the other variations correlate with other large public health issues. Perhaps post-WWII something happened in the health care space?
