Islam is the fastest growing religion in the world today. Conversions are a major factor but natural growth is the main reason. Statistically Muslim women have the highest fertility rates in the world. According to the Pew Research Center by the year 2050 Muslims will equal the number of Christians for the first time in history. Currently, the most popular name in the world is Muhammad. And perhaps most interesting is the fact that Muhammad (alternate spellings included) is the most popular name for newborn boys in England and Whales.
