V-Dem Dataset - Version 11.1
Note: For v11, there was a mistake in aggregating a number of A and A* variables from country-date to country-year by using the wrong aggregation method, most often using maximum instead of last or last instead of maximum per country-year. Most indices were not affected by this as they get calculated using country-date inputs. The following indices were affected and were recalculated for v11.1, the number of changed observations in comparison to v11 are in parenthesis: v2x_horacc (all), v2x_accountability (all), v2x_veracc (all), v2x_diagacc (all), v2x_divparctrl (45), v2x_feduni (8), v2x_regime (24), v2x_regime_amb (25), v2x_ex_confidence (17), v2x_ex_direlect (8), v2x_ex_hereditary (21), v2x_ex_military (52), v2x_ex_party (27). The affected A and A* variables were re-aggregated using the correct method for v11.1.

This quickstart guide is largely an extraction of text from the codebook, but is compiled as a means for a first quick look at the V-dem dataset. For reference, detailed explanations, cautionary notes, and information on all variables, please view the codebook and our other reference documents. Access the guide here: Quick Start Guide (1.1 MB)
What's New and Cautionary Note:
These notes are also included in the dataset packages.
- CSV: When loading the csv file into a statistical software one must specify the encoding as UTF-8 and the delimiter as comma. In Microsoft Excel 2016 that would work the following way: Data -> Get External Data -> From Text; Choose the csv file, this opens the Text Import Wizard; Specify 'Delimited' and choose '65001: Unicode (UTF-8)' as File origin.
- STATA-IC: Example to select individual variables from a large dataset: use country_name v2x_polyarchy using V-Dem-CY-Full+Others-v9.dta
