Not sure of the exact numbers, but trying to recall some stats/percentages I read a while back: in the first two to three decades of the 20th Century Whites were around 25% of the world’s population. But now, with the incredibly rapid increase of the non-White population in the last 100 years or so, Whites are now only about 10-15% of the world’s population and still decreasing.

This is an incredibly important point. I wonder if Spengler was familiar with the work of the American racialists Madison Grant as well as Lothrop Stoddard? This is precisely the point made by Lothrop Stoddard in his very important book THE RISING TIDE OF COLOR – http://books.google.com/books?id=Nv7TeKoQuRYC&source=gbs_navlinks_s

And we see this exact thing happening in modern times, in the past few decades especially. In the past few decades non-Whites around the world have been using White-invented technologies (medical treatments, agricultural advances, sanitation, etc) in order to increase their carrying-capacity far beyond anything they could have achieved via their own ingenuity. As a result of non-Whites using these White-invented technologies they have been massively outbreeding Whites for many decades now…and we are even subsidizing this overbreeding of Blacks, Asians, and Hispanics by sending them untold billions in food aid, medical aid, and so forth EVERY YEAR. Thus we Whites are in some respects financing our own eventual racial-replacement. This is insanely suicidal in terms of the long-term survival of Whites and as such this subsidizing of unchecked non-White overbreeding must be halted sooner rather than later.
