How the sector is decided

A sector is read from the organisation’s own name (“Mercy Hospital”, “First National Bank”, “Lincoln School District”) and from the register it filed with (every notice on the US health department’s breach portal is a health organisation’s). A name that says nothing has no sector, and a name can mislead now and then, so these figures are a floor. Found one in the wrong place? Tell us.
