Tables

This database includes several tables highlighting the hierarchical nature of the North American Industrial Classification System (NAICS) and the North American Product Classification System (NAPCS) codes. Data are current as of 2017. 

  • Under the NAICS group pulldown menu:
    • NAICS (all code levels) lists all codes, their titles, and their definitions. Depending on its level in the hierarchy, the title appears again in one of the columns, which are arrayed from most specific to most general, and every entry to the right shows the hierarchy within which the code is embedded.
    • NAICS 2-digit lists the codes for "sector" (the highest level of generality) and their titles.
    • NAICS 3-digit lists the codes for "subsector," their titles, and which sector they belong to.
    • NAICS 4-digit lists the codes for "industry group" and the codes they belong to.
    • NAICS 5-digit lists the codes for "industry" and the codes they belong to.
    • NAICS 6-digit lists the codes for "national industry (U.S.)" and the codes they belong to.
  • Under the NAPCS group pulldown menu:
    • NAPCS (all code levels) lists all codes and their titles. Depending on its level in the hierarchy, the title appears again in one of the columns, which are arrayed from most specific to most general, and every entry to the right shows the hierarchy within which the code is embedded.
  • NAPCS 2-digit lists the codes for "sector" (the highest level of generality) and their titles.
  • NAPCS 3-digit lists the codes for "subsector," their titles, and the sector they belong to.
  • NAPCS 5-digit lists the codes for "division," their titles, and the codes they belong to.
  • NAPCS 7-digit lists the codes for "group," their titles, and the codes they belong to.
  • NAPCS 9-digit lists the codes for "subgroup," their titles, and the codes they belong to.
  • NAPCS 11-digit lists the codes for "trilateral product," their titles, and the codes they belong to.

Instructions

Here are the principal views for this database:

  • Each table in the left-hand column opens in summary view:
    • By default the table sorts by the first column but you can click on any column title to change the sort order.
    • The summary view shows only a few rows at a time, but use the pager tool to gain access to the rest.
    • This is also the view you will see after conducting a search.
    • The right arrow opens a new tab with a link to the item in question.
  • Clicking the paper icon on the leftmost column of the summary table opens a detail view for the record clicked.
    • The "previous/next" links will take you through any summary table, whether the full dataset or the result of a search.
    • In some cases, the detail view may reveal a field not included in the summary view.
    • For tables listing detailed codes, the detail view also includes a list of those codes at one level of greater specificity that belong to this code.
  • You can conduct a "quick search" by one or two fields from the summary view. However, you can also click the search button to open a full-featured search:
    • You can enter one or more fields. Don't overdetermine a search.
    • By default, the search is conducted as a Boolean AND of terms in any field but you can change this to Boolean OR in the dropdown.
    • Fields with "equals," "starts with," or "contains" require a text entry.
    • Be sure to "clear" the search to get back to the full summary listing.
