Ancient army numbers

Total latins 74300 from cenus figure of 273k latins gives us Romes MPR of 27%

27% of the military census. The military census only counts adult male citizens. Perhaps 5% of the actual total population. Note how the census figures explode as we go from the Republican period to the Augustan period; the leading explanation is that Augustus switched from counting only adult male citizens to counting all citizens.

Polybios gives 770k mil from a free population of c3.4 million, a MPR of 22%.

Polybius give a military census of 770,000 [or so] from a free population of about 3,400,000, or a total population of on the order of 5,000,000 if we count slaves and if we count the subject provinces [as in the methods I described above].

Polybius' totals grow to at least 835,000 if we add the armies and garrisons to the military census figures, and are rather less if we only count the military census figures.
