The total number of Jews worldwide is difficult to assess because the definition of "who is a Jew" is problematic; not all Jews identify themselves as Jewish, and some who identify as Jewish are not considered so by other Jews. According to the Jewish Year Book (1901), the global Jewish population in 1900 was around 11 million. The latest available data is from the World Jewish Population Survey of 2002 and the Jewish Year Calendar (2005). In 2002, according to the Jewish Population Survey, there were 13.3 million Jews around the world. The Jewish Year Calendar cites 14.6 million. It is 0.25% of world population.
