The City & County of Honolulu--with over a million people--is the nation's tenth or eleventh largest city.  It is not the 55th largest (i.e., 350,000 people) as many databases show.  It should have been one of the 29 cities surveyed for this study.  
Please tell the nation's statisticians that they need to correct their data--or else break up other city-county amalgamations like Indianapolis.
