Fastest Growing Religion

"In a number of respects, Islam actually isgrowing faster than Christianity. Islam's growth rate of 2.15 percent annually does exceed Christianity's rate of 1.45 percent. It is worth pointing out, however, that 96 percent of the growth of Islam is attributable to biological growthchildren born into Muslim families. Islam is flourishing in parts of the world where population growth is high. Christianity, increasingly decentralized, has its traditional base in parts of the world where population growth is quite slow or has come to a standstill. Thus, the overall trends do show Islam growing faster than Christianity."
