alt Hacker NewsIn my case it was:
Preston, S. H., Heuveline, P., & Guillot, M. (2001). Demography: Measuring and modeling population processes. Blackwell Publishers.
In GP's case I believe they are correct the Hajnal source is not relevant to the Yangtze Basin but reading the first page should have made it clear the facts could be simultaneously true regardless where the percentages came from or if they were accurate.
Again, there are plenty of problems with the site. That it was clear these facts can't all be true simultaneously was just not one of them.
This appears to be a general introductory demography textbook. I am surprised that you looked at it and it contains specific demographic tables about marriage rates at specific time periods? Perhaps I am misunderstanding what you mean by 'I looked at one of the sources and saw it did not involve newborn rates.'
