I applied the capture-recapture method to estimate the World Trade Center tower population at the time of the September 11, 2001, terrorist attacks. Available lists helped identify 8965 survivors and 2152 confirmed casualties. The capture-recapture model suggested that an additional 4435 survivors were present, putting the total count of all present at 15,552 (95% confidence interval=15,216, 15,897). An accurate estimate represents the potential number at risk for trauma as a result of direct exposure to the events of the day.
我运用捕获再捕获法来估算2001年9月11日恐怖袭击发生时世贸中心双塔内的人员总数。现有名单帮助确认了8965名幸存者和2152名已证实的遇难者。捕获再捕获模型表明,当时还存在另外4435名幸存者,这使得当时现场的总人数达到15552人(95%置信区间=15216, 15897)。准确的估算代表了因直接暴露于当日事件而可能遭受创伤的潜在人数。
