Hat Manufacturing Stats 1899 to 1950

OK, so I saw a Hat Life Yearbook from 1951. It contained this manufacturing info...
(If you can think of what thread this should be merged with, editors, go ahead and do so.)

Is this worldwide? It blows my mind to imagine nearly 36 million hats being made in 1909. For reference, the U.S. population was 90 million.

According to the page the info was from the U.S. Census Bureau as compiled by the Hat Institute. So, it appears to be just the USA.
