Actually, population is increasing in most of western europe...
Mostly due to immigration. Czech pop. is also increasing, but almost entirely due to immigration. We're currently experiencing a spike in natality thanks to the strong generation born in late 1970's (the last baby boom in Czechoslovakia), but that is a temporary matter. Without immigration, Czech population would shrink to some 6-7 million by 2050.
Western Europe receives more immigrants, but except France and a handful of other countries, the native birth-rates aren't much better.
And personally, I think Europe is a way too overcrowded, it could use some gradual natural reduction of its population. I hope more people move to cities so that we can start reforesting Europe and restoring the wildlife in a semi-natural conditions.
