Government agencies are the primary source of U.S. and international statistics.
For U.S. statistics, the best place to start is with the Statistical Abstract of the United States, a compendium of statistics that runs through 2012. A print version of the 2013 Statistical Abstract of the United States may be found in the library's reference section, REF HA202 .P7 2013.
