Macro View of USPC 351 to NAICS

USPC to NAICS probabilities:

USPC Class	NAICS Code	Description	Allocation
351	32	Manufacturing	4.713%
351	33	Manufacturing	95.287%

Why don't the percentages in MACRO and MICRO Match?

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).
