Main file, Stata .xls contains all the main variables concerning democracy, variously defined, through 2003 as described in SCID, 2006.
Analysis file 1, Stata contains additional variables needed to replicate the SCID analysis.
Analysis file 2, Stata contains the data needed for the SCID analyses of the "Maddison years" (Be careful: this file is not as well documented as the others, it is organized in a "wide" rather than "long" format, and the nation codes are not consistent with the other files.)
