The singles generation syndrome is gradually gaining a foothold in Poland and is close to reaching epidemic proportions in much of the West. There have been generations overrepresented by widows and war orphans in the wake of massive military conflicts in the past. But this is probably the first singles generation that is turning away from the concept of the traditional family and going it alone or creating alternative forms such as test-tube babies, uterus rentals, homo adoptions, etc.
What do you think the economic, cultural, political, demographic, psychological and other impact of this development will be in 10, 20, 30 years from now? That is assuming it continues. Such projections based on what is are always risky because life has a way of surprising people and playing tricks on forecasters. This phenomenon applies mainly to the West and emerging countries such as Poland, but there are parts of the world (and minority enclaves in the West) experiencing demographic explosions. France's comparatively high birth rate is largely bolstered by its Moslem minority.
The reasons (economic, cultural, religous) have indeed been discussed but I don't recall seeing any projections. What is we all can see about us, but the interesting thing is where it may lead, what kind of society we will be living in 10, 20 or 30 years from now..
