That said, the book lists for just 20 dollars and is a wonderful overview of the statistical changes in the United States during the 20th century,

It would be a great teaching tool for high school classes. (If I were using it in a classroom, I would give the students the graphs and then ask them to explain them — without looking at the text.)

The same book written at the level that I would prefer would probably cost ten times as much, given the smaller audience for such a work.

]]>I have one beef with the graph. The replacement level line is misleading. The infant and childhood mortality rates in 1901 were higher than they were in 2000, so the replacement level line should be sloped or clearly labeled as the present replacement level.
