"The trend of recent research is pointing to a figure more like 45% to 50% of the European population dying during a four-year period. There is a fair amount of geographic variation. In Mediterranean Europe and Italy, the South of France and Spain, where plague ran for about four years consecutively, it was probably closer to 75% to 80% of the population. In Germany and England, it was probably closer to 20%." Philip Daileader, The Late Middle Ages, audio/video course produced by The Teaching Company, 2007. ISBN978-1-59803-345-8.
Stéphane Barry and Norbert Gualde, in L'Histoire no. 310, June 2006, pp. 45–46, say "between one-third and two-thirds"; Robert Gottfried (1983). "Black Death" in Dictionary of the Middle Ages, volume 2, pp. 257–267, says "between 25 and 45 percent".
Daileader, as above; Barry and Gualde, as above, Gottfried, as above.

Benedictow, The Black Death 1346–1353: The Complete History, Boydell Press (7 December 2012), pp. 380ff.) suggests a death rate as high as 60%, or 50 million out of 80 million inhabitants.
