Both publishers state in their own words that these files are incomplete; this measures how, in counts, with no estimation and no share over an empty denominator.",
  "fieldStateMeaning": "The three counts are in the order published as `field_state_order`: present is a recorded value, explicit_unknown is a value the publisher records to mean it could not be determined, and not_recorded is an empty cell. A recorded unknown is neither present nor missing, and folding it into either one is the error this project exists to refuse.",
