Technical Appendix Levels and trends in the sex ratio at birth in seven provinces of Nepal between 1980 and 2016 with probabilistic projections to 2050: a Bayesian modeling approach

This web appendix is for the preprint Levels and trends in the sex ratio at birth in seven provinces of Nepal between 1980 and 2016 with probabilistic projections to 2050: a Bayesian modeling approach.

Global estimation and scenario-based projections of sex ratio at birth and missing female births using a Bayesian hierarchical time series mixture model

The sex ratio at birth (SRB) is defined as the ratio of male to female live births. The SRB imbalance in parts of the world over the past several decades is a direct consequence of sex-selective abortion, driven by the co-existence of son preference, …

Calculating Missing Female Births

We explain in greater detail how missing female births has been calculated in our recent study.

Levels and trends in the sex ratio at birth and missing female births for 29 states and union territories in India 1990-2016: A Bayesian modeling study

The sex ratio at birth (SRB) has risen in India and reaches well beyond the levels under normal circumstances since the 1970s. The lasting imbalanced SRB has resulted in much more males than females in India. A population with severely distorted sex …

Systematic assessment of the sex ratio at birth for all countries and estimation of national imbalances and regional reference levels

We identify 12 countries with strong statistical evidence of SRB imbalance during 1970--2017, resulting in 45.0 (95% uncertainty interval [36.4; 54.8]) million missing female births globally. The majority of those missing female births are in China, …

Web Appendix Systematic assessment of the sex ratio at birth for all countries and estimation of national imbalances and regional reference levels

This web appendix formed part of the original submission and has been peer reviewed. The journal post it as supplied by the authors. Supplement to: Chao, F., Gerland, P., Cook, A.

A Systematic Assessment of National, Regional and Global Levels and Trends in the Sex Ratio at Birth and Identification of Countries With Outlying Levels

We implemented Bayesian methods for probabilistic sex ratio at birth (SRB) estimation and projection for all countries based on an extensive database with data from vital registration systems, censuses, and surveys. We identified countries at risk of …

A Systematic Assessment of National, Regional and Global Levels and Trends in the Sex Ratio at Birth and Identification of Countries with Outlying Levels

Under normal circumstances, the sex ratio at birth (SRB) has been reported to vary between 1.04 and 1.07. But gender discrimination and other factors associated with the SRB can result in different SRB levels. While SRB estimates have been published …
