Apart from the uncertainty of such calculations, especially as to a commercial city with houses of six stories, we must remember that the numbering is doubtless to be understood in a political, not in an urban, sense, just like the numbers in the Roman census, and that thus all Carthaginians would be included in it, whether dwelling in the city or its neighbourhood, or resident in its subject territory or in other lands.

There would, of course, be a large number of such absentees in the case of Carthage; indeed it is expressly stated that in Gades, for the same reason, the burgess-roll always showed a far higher number than that of the citizens who had their fixed residence there.
