There are rounding errors experienced when converting USPC Classes to NAICS codes. Items with less than ~2.5% influence in a category are removed for clarity. For instance, multiple Micro classes can sum up to a Macro class greater than 2.5% without being delineated. Or a Macro view shows a number far larger than the sum of Micro categories because many small contributors were not shown. Eliminating categories (Macro or Micro) with less than ~2.5% influence results in small differences between the figures above and those below (to the right).
