Unit 00 · Where the data actually lives

Every public health dataset, and how to get at it.

Finding health data is not the hard part. Knowing which source answers your question, how to query it, and what will bite you — that is the hard part. This is our working registry, published openly and kept current automatically.

This catalog describes where public health data lives and how to access it. It is not medical advice, and it does not host or redistribute the data itself — always read each source's own documentation, licence, and suppression rules before using it. Access details drift; entries carry the date we last verified them. Sources marked RESTRICTED are listed for reference only — they require an application or data-use agreement and we never automate access to them.
