Sten Johansson,Ola Nygren +1 more
TL;DR: The missing girls in Chinas high sex ratios verifies Hulls analysis and 1) assumes 105-106 boys per 100 girls as evidenced by 240 years of Swedish demographic data and 2) verifies the sex ratio for reported second and higher parity births bases on the 2 per thousand fertility survey (SFPC2) in 1988 3) introduces adopted children data from SFPC2 which accounts for 50% of the missing girls and 4) calculates excess female infant deaths based on international demographic data for 130 boys per100 girls as the expected ratio as discussed by the authors.
