China’s next census will be conducted in 2020. This time the Seventh National Population Census of the People's Republic of China must get it right. The shadow of a grievous flaw from the last Chinese census hangs over this year’s census. The infant mortality rate (IMR), the rate of infants dying under the age of one, from data in the 2010 Census was highly erroneous. The faulty data obscured one of the gravest offenses to gender equality in the 21st century. Since 2000, there has been no reasonably reliable census for analyzing IMR. The data in that year indicated widespread infanticide.
