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.
