DATA COLLECTION DESCRIPTION Ted Robert Gurr POLITY II: POLITICAL STRUCTURES AND REGIME CHANGE, 1800-1986 (ICPSR 9263) SUMMARY: Carried out under the auspices of the Data Development for International Research (DDIR) project, POLITY II was designed to develop longitudinal indicators of political structures and regime change. This file encompasses most member states of the international system from 1800 to 1986, and consists of annual codings of regimes' structural characteristics, institutional changes, and the directionality of changes on underlying dimensions of democracy, autocracy, and power concentration. CLASS IV UNIVERSE: Annual observations from 1800 to 1986 of 20 historical countries and 132 contemporary countries encompassing virtually all independent countries with populations of one million or more in the 1980s. NOTE: This collection succeeds an earlier study by the principal investigator and Erica Gurr titled POLITY DATA: PERSISTENCE AND CHANGE IN POLITICAL SYSTEMS, 1980-1971 (ICPSR 5010). Each case represents a country-year observation. The data contain blanks and other nonnumeric codes. RESTRICTIONS: Copies of pre-publication papers using the POLITY II dataset should be sent to the authors of the related publication cited below.

Moore, Keith Jaggers & Ted Robert Gurr Re: Minor Errors Through feedback from a number of you as well as our own analyses we have discovered a number of minor errors in the POLITY II data. Rather than redistribute the data via tapes and diskettes we have decided to circulate a memo which details the errors and leave it to you to make the corrections. THE FU&GWINGCHANGKS SHOULDBE MADE: United Province of Central America (0891, 1838 - CHANGEshould be 2 (from .). Columbia (1001, 1853 - CHANGEshould be 4 (from 1). Paraguay (X0), 1985-86 - PAMXMP should be 2 (from 7). Denmark (390), 1866 and 1945 - CHANGKshould be . (i.e., missing) (from 0). Nigeria (475), 1978 - CHANGEshould be 2 (from .) and Scope should be 88 (from 2). Lesotho (5701, 1983-86 - REGION should be 23 (from 3). Elotswana (5711, 1986 - RGGIGN should be 23 (from .). Ottoman Rnpire/Turkey (640), 1919-1922 -The AUTHORITYCHARACI'lBSISTICS during the transition from the Ottoman Empire to Turkey during the years 1919- 1921 should be 77 (from .). For 1922 they should be 88 (from .). All of the other variables should remain as coded. ban (6981, 1970 - CHANGEshould be 4 (from .). Korea (730), 1876 - #is year is entered twice. Australia (920), 1965-67 - REGION should be 3 (from .). AURX! & DEMOCDURING POLITY TR4NSITIONS/IWICBJS/INTKRKEGNUMS: When there is a polity interruption or interregnum (i.e., authority characteristics = 66, 77, or 88) both AUTUC snd DEMGCare coded as zero. It makes sense to change these to a missing value such as 99. 'II-ERE ARE 'IWO CASES THAT ARK MISSING: 1. The year 1977 is missing for Sierra Leone (451).
