Democracy-Dictatorship (DD),[1] index of democracy and dictatorship[2] or simply the DD index[3] or the DD datasets was the binary measure of democracy and dictatorship first proposed by Adam Przeworski et al. (2010), and further developed and maintained by Cheibub, Gandhi, and Vreeland (2009).[4] Note that the most recent dataset was updated 2008.
Based on the regime binary classification idea proposed by Alvarez in 1996,[5] and the Democracy and Development (or DD measure, ACLP dataset) proposed by Przeworski et al. (2010), Cheibub, Gandhi, and Vreeland developed a six-fold regime classification scheme, resulting what the authors called as the DD datasets.[1]: 68
The DD dataset covers the annual data points of 199 countries from 1946 (or date of independence) to 2008.[1]: 68 The figures at the left show the results in 1988 and 2008.
