John Dunne and Li-Chun Zhang's reply to the Discussion of ‘A system of population estimates compiled from administrative data only'
本文介绍了一个仅使用行政数据为爱尔兰编制年度人口估计的系统，通过扩展传统双重系统估计方法，解决了行政登记中的错误登记问题，并用于调查2016年人口普查的低估情况。
This paper presents a novel system of annual Population Estimates Compiled from Administrative Data Only (PECADO) for Ireland in the absence of a Central Population Register.The system is entirely based on data originated from administrative sources, so that population estimates can be produced even without purposely designed coverage surveys or a periodic census to recalibrate estimates.It requires several extensions to the traditional Dual System Estimation (DSE) methodology, including a restatement of the underlying assumptions, a trimmed DSE method for dealing with erroneous enumerations in the administrative register, and a test for heterogeneous capture probabilities to facilitate the choice of blocking in applications.The PECADO estimates for years 2011-2016 are compared to the Census counts in 2011 and 2016.We demonstrate how the system can be used to investigate the Census 2016 under-count in Ireland, in place of the traditional approach of deploying additional population coverage surveys.
