	A population decline from 110,000–120,000 to 50,000 represents a loss of 55–64%. That cannot simultaneously be described as "80% died." If 80% had died, the post-plague population would have been 22,000–24,000, not 50,000. The two figures are mutually exclusive, yet the article presents them side-by-side in the same paragraph without acknowledging the discrepancy. One of the two figures — either the surviving population count or the 80% mortality claim — must be wrong, but the article gives no indication of which to trust.

			== Florence's 80% four-month mortality claim is inconsistent with the stated population before and after the plague ==

			The Deaths subsection gives two Florence figures that, taken together, produce an implausible result:

			# "the population of Florence was reduced from between 110,000 and 120,000 inhabitants in 1338 to 50,000 in 1351."
			# "Florence's tax records suggest that 80% of the city's population died within four months in 1348."

			Taking a mid-range pre-plague population of ~115,000, an 80% death toll in four months of 1348 would leave only about 23,000 survivors. For the city to record 50,000 inhabitants in 1351—just three years later—that survivor pool of ~23,000 would have had to grow by more than 100% in the immediate aftermath of a catastrophic pandemic. This is implausible: births, immigration, and return migration in a depopulated, economically disrupted city cannot plausibly double the population within three years.

			By contrast, the longer-run figures tell a coherent story: a decline from ~115,000 (1338) to 50,000 (1351) is a ~56% reduction over thirteen years, consistent with waves of plague deaths, subsequent recurrences, reduced birth rates, and emigration.

			The two claims can be reconciled only if:
			* the "80%" figure applies to a much smaller subset (e.g., only registered taxpayers, or one district), and should not be read as covering the whole city's population; or
			* one of the two population figures is substantially wrong.

			As presented, the combination of "80% died in four months in 1348" with "50,000 survived to 1351" from a starting point of ~115,000 is internally inconsistent. The article should either clarify the scope of the 80% statistic or note that it conflicts with the overall population trajectory.

Florence: 80% mortality claim contradicts the surviving population figures in the same paragraph: new section

New page

== Florence: 80% mortality claim contradicts the surviving population figures in the same paragraph ==

The article gives two different mortality rates for Florence during the Black Death, and they contradict each other.

In the same paragraph of the Regional effects section, the article states that Florence's population fell from 110,000–120,000 before the plague to about 50,000 after it — a loss of approximately 55–64% of the population. The very next sentence in that same paragraph states: "tax records suggest 80% of the city's population died within four months."

A population decline from 110,000–120,000 to 50,000 represents a loss of 55–64%. That cannot simultaneously be described as "80% died." If 80% had died, the post-plague population would have been 22,000–24,000, not 50,000. The two figures are mutually exclusive, yet the article presents them side-by-side in the same paragraph without acknowledging the discrepancy. One of the two figures — either the surviving population count or the 80% mortality claim — must be wrong, but the article gives no indication of which to trust.
