Demographics

With a population of approximately 93.6 million, Henan is the third most populous Chinese province after Guangdong and Shandong. It is also the fifth most populous sub-national division in the world. If it were a country by itself, it would be the twelfth most populous in the world, just behind Mexico and ahead of the Philippines. However, the hukou system shows Henan as the most populous province in China with over 103 million people, as it counts the migrant Henanese laborers as residents of Henan, instead of the province they currently reside in. On the other hand, Guangdong is shown as having only 81 million people, though the actual population is 95 million due to the influx of migrants from other provinces.

The population is highly homogeneous with 98.8% of the population being Han. Small populations of Mongols and Manchus exists in scattered rural communities as well as major urban centers.Along with Jiangxi, Henan has one of the most unbalanced gender ratios in China. As a result of the Chinese government's one-child policy (many parents do not want the only child to be female and abort the fetus), the gender ratio was 118.46 males for 100 females in 2000. Subsequently, aborting fetuses due to their female sex was banned in Henan and heavy fines are issued for those who violate the law. In addition, daughter-only families receive an annual allowance from the government. Despite these efforts the problem seems to have become far worse. Based on a 2009 British Medical Journal study, the ratio is over 140 boys for every 100 girls in the 1–4 age group; this might be a strong exaggeration, as many families with more than one child do not register their daughters to the hukou in order to escape fines.
