30preservation of statistical accuracy is achieved by evenly distributing fatalities across the linkedincidents. The number of terrorism fatalities per country was converted into a 0–10 scale, where30 was a cut-off (meaning that every country that documented 30 or more terrorism fatalities per1 million population that year received a rating of 0, while the countries with 0 terrorism fatalitiesper 1 million population received a rating of 10; the countries with scores in between these twovalues received corresponding values on a 0–10 scale).iie. Terrorism Injuredby University of MarylandDescription: The number of confirmed nonfatal injuries to both perpetrators and victims.Source: Global Terrorism Database (GTD) includes systematic data on domestic as well asinternational terrorist incidents that have occurred during this time period and now includesmore than 104,000 cases. Statistical information contained in the GTD is based on reportsfrom a variety of open media sources. Information is not added to the GTD unless and until theauthors have determined the sources are credible.Score: Number of injured. It follows the conventions of the “Terrorism Fatalities” field describedabove. The number of terrorism injured per country was converted into a 0–10 scale,where 50 was a cut-off (meaning that every country that documented 50 or more terrorism injuredper 1 million population that year received a rating of 0, while the countries with 0 terrorisminjured per 1 million population received a rating of 10; the countries with scores in betweenthese two values received corresponding values on a 0–10 scale).iii. Women’s Securityiiia. Female genital mutilationby OECDDescription: Measurement of the percentage of women in the country who have undergonefemale genital mutilation.Source: Social Institutions and Gender Index (SIGI) country notes cover 122 countries. Forthe remaining 31 countries we used other credible sources per country (typically two) that differedfrom country to country.Score: Prevalence of female genital mutilation (values are between 0 and 1), where 0 indicatesnone and 1 indicates all. We converted the OECD scores into a 0–10 scale.iiib. Missing Womenby OECDDescription: The coding of countries regarding gender bias in mortality or, euphemistically,“son preference.”Source: The coding in the Social Institutions and Gender Index (SIGI) country notes was donebased on the following information: 1) Existing precise estimates of gender bias in mortality fora sample of countries (e.g., Klasen and Wink, 2003) and 2) examination of the sex ratios of youngpeople and adults; if these sex ratios were abnormally high given the state of overall mortality (i.e.,differences could not be explained by biological and/or socioeconomic factors such as sex-biased internationalmigration), the score reflects the excess masculinity in these two age groups. Social Institutionsand Gender Index (SIGI) country notes cover 122 countries. For the remaining 31 countrieswe used other credible sources per country (typically two) that differed from country to country.Score: Scale 0, 0.25, 0.5, 0.75, and 1, where 0 indicates that no missing women problem canbe detected and 1 indicates a severe incidence of excess female mortality or missing women.
