If we actually followed Church teaching on the marital act our birthrate would be a lot higher

Current birthrate for all US Catholics is around 2.1 births per woman. Numbers vary among subsets... 3.6 births for TLM Catholics, 2.9 births for Hispanic Catholics, 1.8 births for non practicing Catholics. If we as Catholics just follow Church teaching on completion of the marital act we would have a lot more kids and the church would be quickly expanding in the United States.
