In response to the pandemic in early 2020, cities implemented states of emergency and stay at home orders to reduce virus spread. Changes in social dynamics due to local restrictions impacted human behavior and led to a shift in crime dynamics. We analyze shifts in crime types by comparing crimes before the implementation of stay at home orders and the time period shortly after these orders were put in place across three cities. We find consistent changes across Chicago, Baltimore, and Baton Rouge with significant declines in total crimes during the time period immediately following stay at home orders. The starkest differences occurred in Chicago, but in all three cities the crime types contributing to these declines were related to property crime and statutory crime rather than interpersonal crimes.
针对 2020 年初的疫情，各城市实施了紧急状态和居家令，以减少病毒传播。由于地方限制导致的社会动态变化影响了人类行为，并导致犯罪动态发生转变。我们通过比较三个城市实施居家令前后的犯罪类型，分析犯罪类型的变化。我们发现芝加哥、巴尔的摩和巴吞鲁日的犯罪类型都发生了一致的变化，在实施居家令后的一段时间内，总犯罪率显著下降。芝加哥的差异最为明显，但在这三个城市中，导致犯罪率下降的犯罪类型都与财产犯罪和法定犯罪有关，而不是人际犯罪。
