January 4, 2011
This was the second official UDS release. This release extended
the time period covered by the UDS from 1946-2008. These scores
incorporated updates through 2008 to four of the ten original
measures—Freedom House (2010), Polity IV (Marshall et
al. 2010), PACL (Cheibub et al. 2010), and VanHanen
(2009)—that feature in the analysis that we report in our
2010 article. In addition, the release corrected a few minor
errors and added two recently developed measures of
democracy—Mainwaring et al. (2008) and Munck (2009)—to our
framework.
