Distribution of Nobel Prizes by religion between 1901-2000, the data tooks from Baruch A. Shalev, 100 Years of Nobel Prizes (2003), Atlantic Publishers & Distributors, p.59 and p.57: between 1901 and 2000 reveals that 654 Laureates belong to 28 different religion. Most 65.4% have identified Christianity in its various forms as their religious preference. Overall, Christians have won a total of 78.3% of all the Nobel Prizes in Peace, 72.5% in Chemistry, 65.3% in Physics, 62% in Medicine, 54% in Economics and 49.5% of all Literature awards.

While separating Roman Catholic from Protestants among Christians proved difficult in some cases, available information suggests that more Protestants were involved in the scientific categories and more Catholics were involved in the Literature and Peace categories.

Atheists, agnostics, and freethinkers comprise 10.5% of total Nobel Prize winners; but in the category of Literature, these preferences rise sharply to about 35%. A striking fact involving religion is the high number of Laureates of the Jewish faith - over 20% of total Nobel Prizes (138); including: 17% in Chemistry, 26% in Medicine and Physics, 40% in Economics and 11% in Peace and Literature each. The numbers are especially startling in light of the fact that only some 14 million people (0.2% of the world's population) are Jewish. By contrast, only 5 Nobel Laureates have been of the Muslim faith-0.8% of total number of Nobel prizes awarded - from a population base of about 1.2 billion (20% of the world‘s population).
