The IRIS Dataset was originally constructed in 1993 by Steve Knack and Philip Keefer for the IRIS Center at the University of Maryland, based on data obtained from the International Country Risk Guide (ICRG). The dataset includes computed scores for six ICRG political risk variables: corruption in government, rule of law, bureaucratic quality, ethnic tensions, repudiation of contracts by government, and risk of expropriation. Knack produced subsequent issues of the data for an ongoing series of working papers from the IRIS Center. In its current form, IRIS-3 contains data for the period 1982-1997. More recent political risk ratings for all countries monitored by ICRG can be purchased by using the "CountryData" selection wizard on this website.
