Other than in general terms, there's no comparison. The birth rate declining is normal in terms of industrialized countries... people educated enough to use birth control and who have availability tend to have fewer kids.

The birth rate isn't declining because "America is in decline"... it's declining because people are choosing not to have children. The wisdom of that choice is open to discussion, of course.
