# NAICS Codes
> This endpoint retrieves a tree of all NAICS codes identified in the given market. This does not map the NAICS codes to specific domains; this is typically used to create the dropdown list for filtering by NAICS.
A NAICS (pronounced NAKES) Code is a classification within the North American Industry Classification System. The NAICS System was developed for use by Federal Statistical Agencies for the collection, analysis and publication of statistical data related to the US Economy.
It was adopted in 1997 to replace the Standard Industrial Classification (SIC) system in cooperation with the statistical agencies of Canada and Mexico. Their goal was to establish a North American standard. They developed the NAICS as the first economic classification system based on a single economic concept.
While NAICS codes appear as a single integer, they are in fact hierarchical. The first two digits represent the sector, the third digit represents the subsector, and so on; further digits are added to provide more granularity. Typically by being a member of a deeper-level NAICS code, a company is implicitly a member of all parent codes as well.
NAICS codes are self-assigned by companies, without certifications of their validity or accuracy.
This endpoint is deprecated and will be removed in the future. Please use [Attributes](./attributes) instead.
### Path
The ID of the market which you want to retrieve NAICS codes of. This can be retrieved by searching for markets.
### Response
Metadata summarizing the `data` returned.
The number of unique NAICS codes found in the study. This includes all NAICS codes
nested inside the tree, not just the top-level ones.
The number of unique companies containing any of the above NAICS codes.
It is possible that some companies are not mapped to any NAICS codes; these
companies are not included in this count even if they exist in the study.
A tree of all NAICS codes mapped to their number of occurrences, nested by
level. The first level is always an array of the top-level NAICS nodes, which in turn
may have children nodes.
Each node is an object with the following fields:
The NAICS code of this node. This should be unique in the tree, and only
attached to a parent node which has a code that is a prefix of this code.
For example, if a node has a code of `222100`, it should only be a child of
a node with a code of `222000`.
The name of this NAICS code. This is only provided for reference, as different
countries are allowed to have different names for the same code, as is typical
for the deepest level nodes of "National Industries".
Since a market may contain companies from multiple countries, this field may
contain the name as defined by any of the relevant countries.
**Optional**. The number of companies in the study that are mapped to this NAICS code.
**Optional**. An array of child nodes, each following the same structure as this node.
If there are no children, this field will not be present.
