Archaeologists attempt to determine the demographics of past populations with Carbon dating yet admit that the results are not necessarily accurate but believe they can still obtain accurate results by implementing new methods than used in the past, but people are not the only ones who leave behind carbon footprints. There are other things that leave behind carbon footprints as well which, I am afraid, those attempting to deduce a past demographic are not taking into account and therefore still will not be able to obtain accurate results.
