The Most Complete Insights on Consumer Behavior, Period

The Numerator Shopping Behavior Index to Monitor COVID-19 Impact

Numerator is now publishing a weekly Shopping Behavior Index to provide needed visibility into consumer buying behavior shifts driven by the Coronavirus. 

The Numerator Shopping Behavior Index tracks U.S. consumer buying behavior versus year ago across 14 retail channels covering the full omnichannel consumer buying experience. This provides needed visibility into shifts in consumer buying across retail channels, especially as they shift with the spread of the Coronavirus due to increased demand and limited inventory. This report will be available during the duration of the outbreak only.

Numerator publishes consumer behavior data in near real-time to provide brands and retailers the freshest insights available. The Numerator Shopping Behavior Index uses live data, which is essential to understanding dynamic conditions. Featuring live data, the Index refreshes with additional data uploads over time.

Notable Changes:
Given the time panelists are granted to upload their receipts from in-store and online trips, we have restated week 8 to reflect the additional receipts we have received.

We have restated Online given the trailing time for ecommerce receipt processing to better reflect anticipated growth.
