- Lots of people were on the farm
- There was no air conditioning, TV, video games, internet to keep you indoors. even if you lived in cities
Here are a few of the images
Cancer vs percent of agriculture in the state
lots of the population was on the farm back then

Note: the data is not sorted by latitude
However, Skin Cancer increased with solar radiation
