Daily deaths across Italian municipalities in 2020 in excess with respect to 2015-2019

We calculate excess mortality, i.e., attributable to Covid-19, across all (7,272) Italian municipalities using death registry data (see References) by deducting from a municipality's (daily) number of deaths the average number of deaths over the previous five years in the same municipality, using an evenly-spaced-around window of seven days. The date ("GE" column) is in "mmdd" format, while the municipality code ("codice_comune" column) follows standard ISTAT codes. The sample period runs from February to April 2020, and excludes municipalities that were never hit by the Covid-19 disease within the first four months of 2020, i.e. cumulative mortality rate among residents of a municipality did not reach a threshold of 100 deaths per 100,000 inhabitants.

本数据集通过分析死亡登记数据（详见参考文献），计算了意大利（7,272个）所有市政区域因新冠病毒导致的超额死亡率。具体操作为，从各市政区域（每日）的死亡人数中扣除过去五年同时间段内该市政区域的平均死亡人数，采用等间距七天的滑动窗口。日期（“GE”列）采用“mmdd”格式，而市政区域代码（“codice_comune”列）遵循意大利国家统计局（ISTAT）的标准代码。样本期限为2020年2月至4月，并排除了在2020年前四个月未曾受到新冠病毒影响的市政区域，即居民累积死亡率未达到每10万人100人死亡的阈值。
