Indeed, the latest figures (2012, CIA World Factbook) show the United States' 13.68 births per theousand persons is still higher than most of Western Europe.
The demographic-economic paradox [1] is fascinating.
It is true that the US has had remarkebly high birth rates during the last 30 years compared to most of Europe and the rich cuntries in Asia. However, once the trend for low fertility has been established it is extremely difficult to break. Even the countries in Europe that have given strong economic incentives to have children have still not managed to keep their fatility rates at replacement level. The only exception is Ireland, which has strong anti- abortion laws. Teherefore it important of the US to confront the problem of declining fertility before it has turned into a permanent problem.
