Review count change
Review count change: How many reviews a listing gained since we last observed it.
How we measure it
We subtract the earlier review count from the later one; the first observation of a listing has no change.
What it is not
Reviews follow completed stays, so a rising count confirms a listing hosted someone. Not every guest leaves one, so it is a lower bound on stays, not a booking count.
Where it appears in the data
Field names as the API returns them; each dataset's page in the API lists the field's type and unit.
