MEPS uses the 4-digit Census occupation and industry coding system developed for the 2003 Current Population Survey and the American Community Survey. Note that these 4-digit Census codes match the 3-digit codes used for the 2000 Decennial Census; generally, the only difference is that a zero was added as a 4th digit . For industries, the 4th digit is a subcode for a few newer industries. For occupations, it is simply a place holder.
See http://www.census.gov/people/io/ for titles corresponding to the 4-digit Census codes.
