The study was criticised by Sergio DellaPergola, a demographer at the Hebrew University of Jerusalem.Sergio DellaPergola, Letter to the editor, Azure, 2007, No. 27, DellaPergola accused the authors of the AIDRG report of misunderstanding basic principles of demography on account of their lack of expertise in the subject, but he also acknowledged that he did not take into account the emigration of Palestinians and thinks it has to be examined, as well as the birth and mortality statistics of the Palestinian Authority. He also accused AIDRG of selective use of data and multiple systematic errors in their analysis, claiming that the authors assumed the Palestinian Electoral registry to be complete even though registration is voluntary, and they used an unrealistically low Total Fertility Ratio (a statistical abstraction of births per woman) to reanalyse that data in a "typical circular mistake." DellaPergola estimated the Palestinian population of the West Bank and Gaza at the end of 2005 as 3.33 million, or 3.57 million if East Jerusalem is included. These figures are only slightly lower than the official Palestinian figures. The Israeli Civil Administration put the number of Palestinians in the West Bank at 2,657,029 as of May 2012.
