It also determines how catastrophic the Ming–Qing transition was: whether the wars, epidemics and famines of 1620–1680 killed a few tens of millions or a much larger share of the population, and how far the climate-crisis interpretation of the seventeenth century rests on China. Qing-era growth rates, and therefore arguments about the eighteenth-century population boom, depend on where the seventeenth-century trough lay.","stuck":"Official Ming registers record roughly 60 million people throughout the dynasty, a figure that reflects fiscal quotas fixed after 1393 rather than headcounts, so every modern total is a reconstruction. Ho Ping-ti (1959) proposed about 150 million for 1600; later work, including Cao Shuji's prefecture-level reconstruction, puts the late Ming peak close to 200 million, with some estimates higher. The central Yellow Register archive in Nanjing was lost, local gazetteer figures vary in what they count, and corrections for under-registration have been applied region by region with assumptions that are hard to compare.","solved":"A county- or prefecture-level population series for c.1580, 1630 and 1680 covering at least the core provinces, in which every adjustment to registered figures is stated as an explicit, reproducible rule, and whose implied densities and trends are shown to be consistent with independent evidence on cultivated land, land clearance, grain prices and tax arrears.","approach":["Agents can extract every household, ding and mouth figure, land total and tax quota from the digitized Ming and early Qing gazetteers into a single database keyed to CHGIS county boundaries, recording the year and the registration category of each number.","Historians can then specify alternative under-registration models (for example, by ratio of ding to mouths, or by comparison with 1680s Qing registration) and run them consistently across counties, with the agents flagging outliers and internal contradictions for human review.","Cross-checks against grain-price series, reclamation memorials of the 1650s–1680s and local reports of depopulation would test whether a given model produces plausible regional trajectories.","The surviving Yellow Register fragments reused as book-backing paper could provide household-level calibration points if they are systematically imaged and transcribed."],"existing":[{"year":1959,"authors":"Ping-ti Ho","title":"Studies on the Population of China, 1368–1953","venue":"Cambridge, MA: Harvard University Press (Harvard East Asian Series 4)","url":"https://doi.org/10.4159/harvard.9780674184510","note":"Founding study; drew on several thousand gazetteers to show that Ming registered figures were fiscal units and suggested a population of roughly 150 million by 1600."},{"year":1969,"authors":"Dwight H.
