Honolulu’s economy last year was one of the weakest of the nation’s 100 largest metropolitan areas, according to a study released Thursday by the U.S. Conference of Mayors.

Honolulu’s growth rate was 0.0 percent in 2011 from 2010 after adjusting for inflation, tying it with Las Vegas for 91st out of 100, according to the report. Nationally, the growth rate averaged 1.7 percent in 2011 for the 363 metropolitan areas surveyed.

Honolulu’s economy fared better in a 10-year comparison, with its average 4.9 percent growth rate between 2001 and 2011 putting it in the top 25 percent of all metropolitan areas.

The report, prepared by IHS Global Insight, compared cities using a broad economic measure called gross metropolitan product.

Hono­lulu’s inflation-adjusted GMP totaled $51.6 billion, 51st largest out of 363 metropolitan areas.
