is Pakistan's cousin marriage and traditional muslim culture the reason for their high birth rates?

[justinzayn]

, Pakistan has one of the highest rates of cousin marriages at 65%

would most pakistani males die out if there no cousin marriage and islam in pakistan?


also interesting that pakistan punjab and kashmir has way more birth rate then sikh punjab and jammu and kashmir,even though they are the same ethnic group
