“…Therefore, the use of prenatal strategies as measured by sex ratios at birth, and/or women's fertility behavior at low parities as measured by contraceptive use or parity progression, are often appropriate measures of gender preferences for children in lower fertility/transitioning societies. High sex ratios at birth reflecting son preference have been detected in China (e.g., Zeng et al 1993), India (e.g., Arnold, Kishor, and Roy 2002), and South Korea (e.g., Park and Cho 1995). Son preference has also been observed in connection with the cessation of childbearing among women in countries such as Bangladesh (e.g., Rahman and DaVanzo 1993), Egypt (e.g., Vignoli 2006), India (e.g., Arokiasamy 2002), Nepal (e.g., Morgan and Niraula 1995), South Korea (e.g., Larsen, Chung, and Das Gupta 1998), and Vietnam (e.g., Bélanger et al 2003).…”
