估算纽约市街头摊贩数量：基于点过程数据的比率估计
Estimating the Number of Street Vendors in New York City: Ratio Estimation with Point Process Data
AI总结：
本文通过比率估计方法，基于点过程理论估算纽约市街头摊贩数量，发现其数量远超美国社区调查的统计结果。
摘要：
我们估算纽约市街头摊贩的数量。首先，我们总结了摊贩如何通过申请许可证和执照来合法经营的过程。然后，我们描述了由街头摊贩项目在分发新冠纾困援助时向纽约市的摊贩（有执照和无执照）进行的调查。最后，我们回顾了比率估计，并基于点过程理论开发了理论依据。我们发现大约有23,000名街头摊贩在纽约市经营：20,500名流动食品摊贩和2,400名一般商品摊贩。三分之一的摊贩位于仅六个邮编区域：11368（16%）、11372（3%）和11354（3%）在北岸和西区，以及10036（5%）、10019（4%）和10001（3%）在曼哈顿的切尔西和克林顿区。我们的估计表明，美国社区调查未能捕捉到大多数纽约市的街头摊贩。
英文摘要：
We estimate the number of street vendors in New York City. First, we summarize the process by which vendors receive licenses and permits to operate legally in New York City. We then describe a survey that was administered by the Street Vendor Project while distributing coronavirus relief aid to vendors operating in New York City both with and without a license or permit. Finally, we review ratio estimation and develop a theoretical justification based on the theory of point processes. We find approximately 23,000 street vendors operate in New York City: 20,500 mobile food vendors and 2,400 general merchandise vendors. One third are located in just six ZIP Codes: 11368 (16%), 11372 (3%), and 11354 (3%) in North and West Queens and 10036 (5%), 10019 (4%), and 10001 (3%) in the Chelsea and Clinton neighborhoods of Manhattan. Our estimates suggest the American Community Survey misses the majority of New York City street vendors.
