Correction

The version of the 2016 NTI Nuclear Security Index released on January 14, 2016, included several data errors which affected scores for some countries. The data currently on the website, in the report PDF, and in the Excel model reflect the corrections. The revised data does not change the overall NTI Index findings.

In the theft ranking for countries with materials, there was one error in the United Kingdom’s score. In the theft ranking for countries without materials, there were eight errors that affected the scores of Chile, Egypt, Hungary, Indonesia, Morocco, Peru, Sweden, and Taiwan. In the sabotage ranking, there were four errors that affected the scores of Hungary, India, Mexico, and Taiwan. As a result of these errors, there are 13 minor changes in overall score that have been corrected. In addition, rankings for countries whose scores were unaffected by the corrections may have shifted up or down by one or two places from the rankings announced in January 2016.

Please see the tables below for full details on the changes made and their impact.

For a copy of the revised print report, please contact ntiindex@nti.org.

NTI and the EIU apologize for the error.
