CENSITUS, a person censed or entered in the tables of the census. In an ancient monument found at Ancyra, containing the actions of the Emperor Octavius, we read,

Quo iustro civium Romanorum
Censita sunt capita quadragies
Centum millia et sexaginta tria:

From which we learn that the number of Roman citizens, entered in the censor's rolls, was then upwards of four millions.
