To create a list continuous with Chandler's for this, initial period of urban formation (from about -3700, the Early Uruk period) let us consider all cities that fall within the range of 10,000 to 100,000. That seems to be the size of population within which a systemic division of labor might take firm hold. In this ancient era (-3500 to -1200; cf. Modelski and Thompson 1996), the upper limit of city populations seems to have been about 100,000, the size attained on Chandler's list only once, by Avaris, in -1600; McEvedy's first reaching of the 100,000 mark occurs in -825, at Niniveh.
The lower limit of 10,000 is about the same size criterion as McEvedy's and only slightly lower than that implied in Chandler's listings for -2250, 2000 and 1800. That would make inclusion warranted for settlements at least one order of magnitude larger than those comparable to Jericho. We aim to include all cities that meet the criterion of 10,000 but might not, of course, be able to do so due to data limitations.
