## NOTE ON VERSION 4

In this update between version 2.0 and 3.0 (October 10, 2007) version of the data, we have corrected some erroneous codings in the regime type variables for Czechoslovakia (1992), Djibouti (1992-2005), Kyrgyz Republic (1991-1994), Lesotho (1993-1997), Singapore (1972-1980), Tajikistan (1991-1994 and 2005), and Uzbekistan (1991-1993). We also updated the Polity 4 data for the year of 2005 (instead of using imputed scores), which affected the regime classification of the Philippines for that year. Between version 3.0 and 4.0 codings were adjusted for Fiji in the period 2007-2008.

For each variable in the database n refers to the number of observed country years, N to the number of countries covered.

## Country and time coverage

This data set covers the time period 1972-2010 and includes all 192 nations recognized as members of the UN except the four "micro states" of Europe (Andorra, Liechtenstein, Monaco and San Marino) and two "micro states" in the Pacific that are not members of the World Bank (Nauru and Tuvalu). In addition, we have included Taiwan and seven states that have dissolved or merged with other states: the USSR, Czechoslovakia, the Federal People's Republic of Yugoslavia, East Germany, North and South Yemen, and South Vietnam. This makes a tally of 195 states. We have treated Germany as a continuation of West Germany, Vietnam as a continuation of North Vietnam, and Ethiopia as a continuation of itself before the secession of Eritrea. By contrast, we treat the Republic of Yemen, the Federal Republic of Yugoslavia (Serbia and Montenegro) and the Russian Federation as new states. In the case of Yugoslavia (Serbia and Montenegro) Serbia is seen as the continuation of this state following the independence of Montenegro. Cyprus refers to the Greek part of Cyprus. Albania is treated as the same case after the independence of Kosovo. Kosovo is treated as a new case from 2009.

This imputation in effect also affects the time-series information on ifhpol for countries with some Polity data (although with less coverage than FH). In rare instances, this means that ifhpol in these countries changes although the underlying FH scores do not change. Source: See fhadd and revpol2.

## Regime classification variables

regime1ny

(n: 6693, N:195) Collapsed regime type 1 Monarchy 2 Military 3 One party 4 Multi-party 9 No-party 99 Other 100 Democracy Using the mean of the Freedom House and Polity scales (ifhpol), we draw the line between democracies and autocracies at 7.0. We chose his threshold value by estimating the mean cutoff point separating democracy from autocracy in five well-known categorical measures of democracy: Cheibub et al. (2010), Boix et al (Forthcoming) and Bernhard et al. (2001)3, together with Polity's own categorical threshold for "democracy" and Freedom House's threshold for "Electoral Democracy." At the core of our typology of authoritarian regime types is a distinction between three different modes of political power maintenance (probably the three most widely used throughout history): 1. Hereditary succession, or lineage, corresponding to Monarchies; we define monarchies as those regimes in which a person of royal descent has inherited the position of head of state in accordance with accepted practice and/or the constitution (one cannot proclaim oneself a monarch). It bears stressing that we only apply this classification to countries where the sovereign exercises real political power; ceremonial monarchies are thus excluded. This occurs in Afghanistan 1979 and 2001, Bosnia-Herzegovina 1995, Cambodia 1979, Lebanon 1990, and Solomon Islands 2003. Users particularly interested in the time-series information on democracy for these countries should consider more case-specific imputation techniques. 2. The actual or threatened use of military force, referring to Military regimes, where the armed forces may exercise political power either directly or indirectly (i.e., by controlling civilian leaders behind the scenes). Regimes where persons of military background are chosen in open elections (which have not been controlled by the military) thus should not count as military. "Rebel regimes" form a special subcategory. They include cases where a rebel movement (one not formed out of the regular armed forces) has taken power by military means, and the regime has not as yet been reconstituted as another kind of regime. 3. Popular elections, designating the various electoral regimes. We distinguish among three basic types of electoral regimes. The first is the No-Party Regime, where elections are held but all political parties (or at least any candidate representing a party) are prohibited. Elections in no-party regimes may display an element of competition, but thus only among individual candidates. Second, in One-Party Regimes, all parties but one is forbidden (formally or de facto) from taking part in elections. A small number of non-party candidates may also be allowed to take part and get elected; there may be satellite parties which are autonomous in name, but which cannot take an independent position; and competition between candidates from the same (ruling) party may also obtain; we still code the regime one-party. It is not enough, moreover, that a regime calls itself a one-party state; elections in such a structure must also be held. Third, and finally, we define Limited Multiparty regimes as regimes that hold parliamentary or presidential elections in which (at least some) candidates are able to participate who are independent of the ruling regime. This classification holds even when opposition parties refrain voluntarily from taking part in elections. It also embraces cases where parties are absent, but where this is not the result of any prohibition against party activities: the candidates in question have simply chosen to stand for election as individuals. These latter we classify as Party-Less limited multiparty systems. Finally, we have a residual category called others, including a few cases that do not fit under any other regime type, given the definitions applied. The categories in regime1ny are not mutually exclusive. All monarchical regimes with amalgams (regimeny=16, 17, 23 or 24) are treated as monarchies, all military regimes with sub-types and amalgams (regimeny=4, 5, 6, 7 or 18) are treated as military regimes, and multiparty regimes with sub-types are treated as multiparty regimes (regimeny =1 or 2). Only pure no-party (regimeny=3) and one-party (regimeny=8) regimes are treated as no-party and one-party regimes, respectively. The minor types (regimeny=9, 19, 20, 21, 22) are treated as other. Our regime classification pertains to December 31 as of each year.

Monarchies may carry out elections in various forms: multiparty elections, no-party elections, and also one-party elections. The same goes for military regimes. In addition to the main types and their amalgams, we have identified several minor types of authoritarian regime. In a theocracy, decisive political power lies in the hands of a religious elite. Temporary regimes, the purpose of which is to carry out a transition, are classified as transitional regimes.7 There are furthermore countries in which the official government does not in reality control the territory. This may be due to civil war or occupation by foreign troops. Source: See regime1ny

## Historical variables and regime duration indicators

yrindep

(n:7605, N:195) Year of independence (1700=1700 or before) We have generally used the data when a state became independent or unified within the (more or less) current borders. This pertains for instance to Hungary, which is coded as independent in 1918 and not in 1001 when it was first unified. Cases of occupation when the occupant power never established any civilian rule has not been counted as cases of colonisation. All countries that became independent in 1700 or prior to this year is coded as yrindep=1700. Source: CIA World Fact Book and Encyclopedia Britannica Online.

## Standard descriptive variables (generated by this package)

extended_country_name

The name of the country in the Gleditsch-Ward system of states, or the official name of the entity (for non-sovereign entities and states not in the Gleditsch and Ward system of states) or else a common name for disputed cases that do not have an official name (e.g., Western Sahara, Hyderabad). The Gleditsch and Ward scheme sometimes indicates the common name of the country and (in parentheses) the name of an earlier incarnation of the state: thus, they have Germany (Prussia), Russia (Soviet Union), Madagascar (Malagasy), etc. For details, see Gleditsch, Kristian S. & Michael D. Ward. 1999. "Interstate System Membership: A Revised List of the Independent States since 1816." International Interactions 25: 393-413. The list can be found at http://privatewww.essex.ac.uk/~ksg/statelist.html.

GWn

Gleditsch and Ward's numeric country code, from the Gleditsch and Ward list of independent states.

cown

The Correlates of War numeric country code, 2016 version. This differs from Gleditsch and Ward's numeric country code in a few cases. See http://www.correlatesofwar.org/data-sets/state-system-membership for the full list.

in_GW_system

Whether the state is "in system" (that is, is independent and sovereign), according to Gleditsch and Ward, for this particular date. Matches at the end of the year; so, for example South Vietnam 1975 is FALSE because, according to Gleditsch and Ward, the country ended on April 1975 (being absorbed by North Vietnam). It is also TRUE for dates beyond 2012 for countries that did not end by then, depsite the fact that the Gleditsch and Ward list has not been updated since.
