It has been almost 25 years since the last Significant Features data book was published in 1996.

Our ambition is to complete the online 2020 edition of Significant Features of American Federalism by the end of the year. Data tables will be added on this website as they are completed throughout the year.

Pulling together data from various different data sources and preparing dozens of tables is not an easy feat. Especially not when the effort relies exclusively on volunteer contributors.

Please email Jamie Boex (jamieboex@gmail.com) if you are interested in joining us and wish to contribute to the effort.
