Yes that is correct, or to be more precise, all items that are humans
(instance of Q5) and have both, a time- and geo-coordinate. So if for
example an item would have a birth date specified but no place of birth
(or the other way around) it won't be included in the extracted births
dataset.

Oh, and something that I forgot to mention earlier: The application is
quite performance intensive and is best viewed in Chromium (or Chrome)
if possible.
