On March 30, 2008, a Sunday, CNN had a news item on religion that summarized the newspaper L’Osservatorie’s interview with Monsignor Vitterio Fomenti, the producer of the 2006 Year Book of the Vatican. It is recognized in the yearbook that 19.2% of the world’s population are Muslim adherents while Roman Catholics is at 17.4%. All groups that are denominated “Christian” compose about 33% of the world’s population.
It is revealed that the figure on Muslim population was taken from numbers submitted to the United Nations by Muslim states. The article also states that most “Christian” countries have population management programs while Muslim states have large families.
