Ramadan, a month of daytime fasting, draws attention to our 3rd largest religion. The Muslim population in the U.S. has increased most dramatically in the 20th century, due to a higher birth rate and the immigration of Arabs and South Asians. About 72% of American Muslims are 1st or 2nd generation Americans. 2005 saw a great increase in the number of Muslims becoming legal residents (96,000). And so today, it is likely you have a Muslim neighbor, coworker, or classmate.
