Overview

Each data source and level of aggregation has a separate CSV, named using the following convention: Data sourceGeographic Level of AggregationTemporal Level of Aggregation

Additionally, we have three files, GeoIDs – State and GeoIDs – County and GeoIDs – City, that provide information on geographic crosswalks and aggregation. These can be merged to any file sharing the same geographic level of aggregation using the geographic identifier. Additionally, GeoIDs – County indicates the commuting zone (CZ) and state that each county belongs to. The City-level data (listed under “Metro” on the tracker site) associates the largest cities in the United States with a representative county one-to-one (except in the case of New York City which includes the 5 boroughs).

Finally, we have gathered a collection of key state-level policy dates relevant for changes in other series trends and values. These are contained in the Policy Milestones – State file.

A description of the columns in each file follows.

Data File Descriptions

Affinity

Credit/debit card spending data from Affinity Solutions.

All spending variables are measured relative to January 6 to February 2, 2020, seasonally adjusted, and calculated as a 7 day moving average. When we subdivide by income using the median income of the ZIP codes, q1 is the quartile with the lowest median income and q4 is the quartile with the highest median income. At the national level, we release a variety of breakdowns without seasonal adjustment in variables that begin with spend_s_ (relative to January 2019 for 2019 data, relative to January 2020 for 2020 data onward) or spend_19_ (relative to Janurary 7 to February 3, 2019 for all data) instead of spend_.

The merchant category codes (MCC) making up the grouped spending categories are:

In addition, four supplemental files are included (see the documentation for more details on these files):

Job Postings

Job postings data from Lightcast (formerly known as Burning Glass Technologies).

In addition, the following supplemental file is included (see the documentation for more details on this file):

COVID

COVID cases and deaths numbers are from the New York Times and the Centers for Disease Control and Prevention, hospitalizations numbers are from the U.S. Department of Health and Human Services, tests numbers are from Johns Hopkins University, and vaccination numbers are from the Centers for Disease Control and Prevention.

Google Mobility

GPS mobility data indexed to January 3 to February 6, 2020 from Google COVID-19 Community Mobility Reports.

Employment

Please note we are planning the release of a new, updated, and overhauled employment series in the coming weeks. This series will much better handle entry and exit from the underlying sample as well as improve on other biases in the current series. As such we advise that users wait for the release of the new and updated data in order before using the Employment series so that users have the most accurate information available.

Employment levels relative to January 4 to 31, 2020 from Paychex and Intuit.

In addition, the following supplemental file is included (see the documentation for more details on this file):

UI Claims

Unemployment insurance claims data from the Department of Labor (national and state-level) and numerous individual state agencies (county-level).

Womply

Small business openings and revenue data from Womply.

In addition, the following supplemental file is included (see the documentation for more details on this file):

Zearn

Online math learning data from Zearn.

Note that for every variable listed here, there is a corresponding variable with the prefix break_ (for example, break_engagement). During the period in which schools are on summer or winter break, we record the outcomes in these break_ variables instead of the usual variables. These numbers are not displayed on the Economic Tracker because they do not reliably measure differences in student learning across geography and income groups when many schools are on break.

To ensure privacy, the results for some counties are masked. Where possible, masked county levels values are replaced by commuting zone means, as indicated by the imputed_from_cz variable. The masking criteria are explained in further detail in our data documentation.

Policy Milestones

Key state-level policy dates relevant for changes in other series trends and values.
