fertility rates are declining in all populations across the earth. including the most religious theocracies. this is a function of technology and welfare systems making children obsolete and women being able to support themselves independent of men by having an education and employment opportunities. soon every country on earth will have below replacement rate fertility. only a few religious populations on earth actually have above replacement fertility (but they are still in decline).  if you think fertility means the religion is right, then you should be amish, mennonite, mormon, or adopt wild spiritualism like the native americans. or maybe you can join the christian niggers in africa.
