Current estimates would suggest the maximum population of Argentomagus to be 3-4,000 inhabitants at the end of the first century and during the second, when the demographic pressure seems to have been at its strongest.

Some religious or funerary inscriptions, graffiti on public monuments, signatures on a painted wall or on vases or a token in bone have revealed the identity of around twenty inhabitants of the town.

Two of these enjoyed Roman citizenship: Quintus Sergius Macrinus and Africanus Proculus. The first was a noble who, with his personal fortune, offered to build a temple. The second had the traditional two names.

All the other individuals identified had a single name. Free men and women but regarded as subjects of the Roman empire, they seem to have originated abroad. Certainly that is the case with two: Eberus and Labrios.

During the second half of the 2nd century A.D. or during the course of the 3rd, Colguron (or Colgurca) has traced his name on a painted wall. The bone tessera found in the theatre has given us the names of two other men: Priscus, son of Amandus. Two pieces of graffiti inscribed on two pillars of the monumental fountain reveal new masculine names: Dometianus and Venerianus. Bladamus and Cato, two androgynous names, appear on two funerary stelae.

The limestone base of one of these funerary stele was discovered in the middle of the 19th century in a railway cutting between Saint-Marcel and Argenton.

It carries the inscription "BLADAMI FIL (ius)" or "son of Bladamus".
