Demographics
With modern Chinese governments advocating smaller families through family planning campaigns and policy-making, large extended families may be a thing of the past. The People's Republic of China introduced its One-child policy in 1979, and The Family Planning Association of Hong Kong began its "Two is enough!" (兩個就夠哂數!) campaign in the 1970s. Contrasted with the large extended families created during the pre-war and baby-boom years, average modern Chinese families now have many fewer children.
As of 2006, the fertility rates in Hong Kong and Macau ranked among the lowest two in the world. Hong Kong, ranked the lowest in the world, was the only territory with less than one child born per woman on the average. Both Mainland China and Taiwan were ranked well below the world average. Similarly, the birth rates in Hong Kong and Macau ranked among the lowest three in the world. Both Mainland China and Taiwan were ranked below the median.
A product of rising divorce rates in Chinese societies is the breakdown of the traditionally close-knit kinship relation. On the other hand, re-marriage could provide more than two sets of paternal or maternal relatives.
