Impact of the coronavirus (COVID-19) pandemic on Employment Cost Index data for March 2021

This page provides further information on the effects of the COVID-19 pandemic for the March 2021 Employment Cost Index news release.

Collection mode

The ECI data are collected by BLS field economists contacting establishment respondents. Respondents may provide information through personal visits, phone, email, electronic file transmission, fax, and mail. Field economists have discontinued personal visits and are relying on the other collection methods at this time.

Response rates

Nonresponse may increase because of difficulty reaching survey respondents or selected jobs having no workers for the reference period. See the historical response rates. Response rates were comparable in March 2021 to the December 2020 release.
