Reexamining the Contribution of Public Health Efforts to the Decline in Urban Mortality: Comment
回应了Anderson等人对我们先前研究的评论，修正数据错误后重新估计，发现市政水消毒（过滤）解释了样本城市总死亡率下降的38%，与原始估计43%相差不大，但婴儿死亡率影响较小。
We address points raised by Anderson, Charles, and Rees (2022b), which comments on our prior work. After correcting unambiguous data mistakes, our revised estimates suggest that municipal water disinfection (filtration) explains 38 percent of the total mortality rate decline in our sample cities and years—a result not very different from our original estimate of 43 percent. However, effects on infant mortality rates are smaller than in our original analysis. Much of the difference between their analyses and ours is due to the coding of partial intervention years and to differences in population denominators, for which ideal data are difficult to find.
