The %-evangelical page says how many people one box stands for

Brief A1.4 asks the page to state how many people each cell represents; it printed the share and the
population but never the unit a reader needs to read the grid ("each box ≈ 40,208 people" for the
whole DOXA list). Computed with the screen chart's own peoplePerCell so paper and screen divide the
same way, in all eleven languages, and omitted when the list has no published data.
