The Statistical Abstract of the United States is a one-volume, comprehensive summary of statistics on the social, political, and economic organization of the United States. It was also designed to serve as a guide to other statistical publications and sources. From 1878 to 2012, it was published by the U.S. Census Bureau, and those volumes are freely available on the Census Bureau web site.
The Statistical Abstract is now published by ProQuest, and the UW-Madison subscribes to the new online edition, starting with the 2013 volume.
The ProQuest online edition has search features that the Census Bureau editions did not, and will be updated monthly.
