This paper investigates the effect of mortality and fertility on the net reproduction rate (NRR) from a dynamic perspective and the impacts they have on India’s demographic characteristics. As a dynamic extension of the net reproduction rate considers both mortality and fertility changes, it has the potential to provide a more realistic and accurate picture of India’s fertility regimes. The estimated values of our “dynamic” NRR are found to be less than the conventional NRR for India as well as for all the states we examined. The results indicate that this difference is mostly driven by changes in fertility. In addition to using several classic demographic measures under both conventional and dynamic approach to study the implications of the NRR on the demographic aspects of the population, we also provide estimates of the minimum time required for attaining stationarity for India and some of its selected major states under the hypothetical condition of imposition of the replacement-level fertility based on both the conventional and dynamic scenario. This comparison reveals that in cases where (1) the difference between conventional and dynamic NRR is small, the projected year of attaining stationarity under the hypothetical situation of imposing the replacement-level fertility does not differ significantly, and (2) there is a striking difference between the conventional and dynamic NRR, the projected year of attaining stationarity differs significantly.

本文从动态角度研究了死亡率和生育率对净生育率（NRR）的影响以及它们对印度人口特征的影响。由于净生育率的动态扩展考虑了死亡率和生育率的变化，因此它有可能为印度的生育率状况提供更现实和准确的描述。我们发现，我们的“动态”NRR 估计值低于印度以及我们研究的所有邦的传统 NRR。结果表明，这种差异主要是由生育率的变化造成的。除了在传统和动态方法下使用几种经典的人口统计指标来研究 NRR 对人口统计方面的影响外，我们还提供了印度及其一些选定的主要邦达到稳定所需的最短时间的估计在基于传统情景和动态情景的强制更替水平生育率的假设条件下。这一比较表明，在以下情况下：（1）传统生育率和动态生育率之间的差异很小，在实施更替水平生育率的假设情况下，预计达到稳定的年份不会有显着差异；（2）存在显着的差异。传统 NRR 和动态 NRR 之间存在差异，预计达到稳定的年份存在显着差异。
