Could it be that China’s abortion policy can be the cause of its eventual demise as a world power?
China would be a world power even if it had a few hundred million less people, don't you think?
China is committing suicide as a civilization. Abortion with their one child policy will mean China’s dominance in the world won’t last more than a generation
US immigration rate is 4.18 per 1000 while China's is minus 0.33 per 1000
So if you calculate these rates with the death rates you end up with a population growth rate with the US being 0.963% per year while China is at 0.493% per year.
Canada achieves about the same population growth rate as the US but she has smaller birth rate and a higher immigration rate.
