What is the difference between tags and categories?

Name: FRED Tags & Sources — Data Discovery
Availability: InStock
Author: Vinkius

Categories are a strict hierarchy (one parent, many children). Tags are flat labels — each series can have many tags across dimensions: geography (usa), frequency (monthly), topic (gdp), source (bls). Combine tags for powerful cross-dimensional filtering.
