I would be very grateful is someone could provide scholarly sources to support the following description of the population of Rome, found on the "Population" page of UNRV website:
* The slave population of Rome approached 500,000 on its own, probably half of which were owned by the 600 men of the Senate. Additional estimates have suggested that of the total 65 million people, 2 to 10 million may have been slaves.
I would also like to study the course of the population in the later empire. I just read Peter Heather's book, who argues that population was growing. Are there counter positions to this?
Thanks,
Jauchart
