This paper examines recent trends in sex ratio at birth in all the major states of India, based on three rounds of the National Family Health Survey. It finds evidence of an increase in the ratio, particularly at the second-order birth among women having a first daughter in many states in the northwestern region of the country. Also, there are signs of daughter aversion emerging in Odisha, an eastern state. Based on parity progression ratios and the trend in sex selection, an attempt is made to estimate the peak of sex ratio at birth in India. With moderate intensification in sex selection in the northwestern region, sex ratio at birth is expected to reach a peak of 117–119 males per 100 females around the period 2021–2026. If, in addition, sex selection spreads further in the southeastern region, the sex ratio at birth in India could even increase to a level of 124. 相似文献

Preparation of the base population plays a substantial role in the accuracy of projections. This paper reviews analytical strategies involved in the preparation of the UN World Population Prospects to reconcile existing discrepancies between data sources and derive robust estimates of population counts, distribution, and demographic changes. The case study of India is used to illustrate the challenges and benefits of using a cohort-component population projection approach in reconstructing its population between 1950 and 2010, including the preparation of bias-free population counts and distributions by age and sex; estimation of consistent fertility and mortality trends; and integration of all demographic components for obtaining a reliable base population for projections. 相似文献

对清代考据学批评之批评 总被引:1,自引:1,他引:0
前人对考据学批评较多的是“复古”、“繁琐”、“门户之见”,这些批评有可商榷之处。考据学重视先秦两汉文献是由他们的研究课题所决定的,具有极大的合理性,并非是复古。繁琐不是考据学者们的追求,他们讲究博征,注明出处是为了增强结论的科学性,不能不加区别地视为繁琐。考据学派中的吴派矫枉过正,确有较深的门户之见,但皖派、扬州学派都主张实事求是,不以汉宋论是非,不偏主一家。 相似文献
