Leverage Candid's Philanthropy Classification System (PCS) Taxonomy in our APIs
Using the PCS in our data
One of the most valuable ways to search for an organization, grant, or news in our APIs is to use Candid’s Philanthropy Classification System (PCS), which is Candid’s taxonomy describing the work of grantmakers, recipient organizations, and the philanthropic transactions between those entities.
Candid’s Classification System is based on the National Taxonomy of Exempt Entities (NTEE) and has been expanded over the last three decades to include the emerging work we have evidenced while capturing and indexing the work of the sector on a global scale.
We enrich the data we aggregate using machine learning algorithms to better understand the social sector. The facets of the PCS illuminate the work and answer the following questions about philanthropy:
- Who? = Population Served
- What? = Subject and Organization Type
- How? = Support Strategy and Transaction Type
