Over the years one of the most valuable resources I’ve tapped for information in my research on the construction industry has been The Construction Chart Book: The U.S. Construction Industry and its Workers. A pdf of the 4th edition published in 2013 is available here.
The Construction Chart Book | CPWR
The fifth edition of The Construction Chart Book presents the most complete data available on all facets of the U.S. construction industry: economic, demographic, employment/income, education/training, and safety and health issues, plus much more.
