Estimates on the overall death toll have varied. Providing detailed statistics of the various estimates of the Churches' population after the genocide, David Gaunt accepts the figure of 275,000 deaths as reported by the Assyrian delegation at the Treaty of Lausanne and ventures that the death toll would be around 300,000 because of uncounted Assyrian-inhabited areas. David Gaunt, "The Assyrian Genocide of 1915", Assyrian Genocide Research Center, 2009. Rudolph Rummel gives the number of Christian deaths in Assyrian-populated regions of Turkey as 102,000 and adds to this the killing of around 47,000 Assyrians in Persia.
