How many people werre there in china before the one child policy?

In 1978, China's population was approximately 956,200,000.
Today it is 1,350,000,000.
The increase was about 41%.

Bear in mind that the policy was really a "one-birth event per urban Han person" policy. The following exceptions were allowed...
– Parents live in a rural area.
– Mother is not Han ethnic group.
– Parents pay a large fine for the second birth.
– Overseas births.
– Multiple fetus births.

You will see a large number of twins in China. I saw two to six pairs of twins weekly walking around Shanghai for nine years. I estimate the gender ratio of twins was 7 to 3 in favor of boys. If a woman is carrying three or more fetuses, she can choose which ones to abort. Fertility drugs increase the chance of multiple-fetus pregnancy.

I have discussed the recent partial rescending of the policy with many Chinese, and most of them are of the opinion the policy did not make much difference in population growth, so partially recending it doesn't matter either.
