They're clearly not being replaced, as a look at the numbers indicates, but what is true for most European countries is that if the low birth rates stay far below 2.1 their populations will continue to decline and their economies will shrink, if they don't manage to offset that trend with controlled yearly immigration.

To clarify: Although it follows mathematically with constantly low birth rate, dying out is, of course, not a likely consequence. It seems likely that at some point when the economies shrink poverty would hit so seriously that the birth rates would start increasing again, as they seem to be negatively correlated with standards of living. However, we're talking about levels of shrinkage that feel like a collapse of the economy and social security/pension systems.
