CT Percent Change in Small Business Revenue

Small business transactions and revenue data aggregated from several credit card
processors, collected by Womply and compiled by Opportunity Insights. Transactions and revenue are reported based on the ZIP code where the business is located.

Data provided for CT (FIPS code 9), MA (25), NJ (34), NY (36), and RI (44).

Data notes from Opportunity Insights:
Seasonally adjusted change since January 2020. Data is indexed in 2019 and 2020 as the change relative to the January index period. We then seasonally adjust by dividing year-over-year, which represents the difference between the change since January observed in
2020 compared to the change since January observed since 2019. We account for differences in the dates of federal holidays between 2019 and 2020 by shifting the 2019 reference data to align the holidays before performing the year-over-year division.

Small businesses are defined as those with annual revenue below the Small Business Administration’s thresholds. Thresholds vary by 6 digit NAICS code ranging from a maximum number of employees between 100 to 1500 to be considered a small business depending on the industry.

County-level and metro-level data and breakdowns by High/Middle/Low income ZIP codes have been temporarily removed since the August 21st 2020 update due to revisions in the structure of the raw data we receive. We hope to add them back to the OI Economic Tracker soon.

本数据集汇聚了由 Womply 收集并 Opportunity Insights 编制的多个信用卡处理机构的中小企业交易及收入数据。交易和收入报告基于企业所在地的邮政编码。提供的数据涵盖康涅狄格州（FIPS代码9）、马萨诸塞州（25）、新泽西州（34）、纽约州（36）和罗德岛州（44）。数据注释来自 Opportunity Insights：自2020年1月以来的季节性调整变化。数据以2019年和2020年为基准，计算相对于1月份指数期的变化。然后通过季节性调整，即通过年同比增长率进行计算，以反映2020年与2019年1月份观测到的变化之间的差异。通过将2019年的参考数据调整至与联邦假日相一致，以应对2019年和2020年联邦假日日期的差异。中小企业定义为年营业额低于美国小型企业管理局门槛的企业，门槛根据6位数的北美行业分类代码（NAICS）而变化，从100至1500名员工的最大数量不等，具体取决于行业。自2020年8月21日更新以来，由于收到的原始数据结构修订，已暂时移除县级和都市级数据以及按高/中/低收入邮政编码的细分。我们希望不久后能够将这些数据重新添加至 OI 经济追踪器中。更多关于 Opportunity Insights 数据的详细文档，请参阅此处：https://github.com/OpportunityInsights/EconomicTracker/blob/main/docs/oi_tracker_data_documentation.pdf
