Updates and Corrections to the NTI Index
Correction: Norway Moves Up Ranking
January 30, 2012
Due to a clerical oversight, the original version of NTI’s Nuclear Materials Security Index released on January 11, 2012 included an error in the scoring of Norway’s quantities of weapons-usable nuclear materials. As a result, Norway’s overall ranking was incorrect in the original version of this report, the website, and the EIU Excel model.
In overall scoring, Norway ties with Poland for 8th, with a score of 82 (rather than ranking 9th with a score of 81 reflected in the original Index release). Within the Quantities and Sites category, Norway has a score of 81, which moved its ranking in this particular category to 13th from 14th. As a result, Ukraine moves to 14th from 13th within this category.
The website, the Excel model, and the PDF version of the report, all available at www.ntiindex.org, include these corrections.
NTI and the EIU apologize for the error.
