Impact of the coronavirus (COVID-19) pandemic on the Import and Export Price Index data for May 2021
This page provides further information on the effects of the COVID-19 pandemic for the May 2021 U.S. Import and Export Price Indexes.
Collection
The Import/Export Price program collects nearly all of its data by web collection. There were no changes to collection made in response to the pandemic.
Response Rates
The impact of the current pandemic on Import and Export Price Index data was relatively minor for May 2021 data published on June 16, 2021. The response rates for the current month’s import prices and export prices are shown in tables 1 and 2 below. In each case, the response rates for the current month’s indexes are compared to the response rates from the previous month, the same month a year ago, and the average response rates for the 12-month period ended February 2020. In all cases, the response rate is the percent of prices requested from respondents that were collected for the initial publication of a given month. Note that the Import and Export Price Indexes are revised in each of the 3 months after initial publication and that response rates improve as more data are subsequently collected.

Index Suppression
Publication quality is evaluated monthly and annually. Each month, the number of respondents contacted and prices requested varies. These changes occur as the market basket is updated monthly to add new representative items and exclude items no longer traded and as respondents establish different schedules to report price changes. Information on the data collection process provides metrics to evaluate the number and representative share of prices that support index quality. Published indexes ensure confidentiality of respondents, sample representativeness, and robustness of coverage for items and companies.
The top-level price indexes continue to be representative of total trade. Detailed indexes face greater likelihood of suppression. If the number of prices collected is insufficient to support index publication, the index’s publication is suppressed for the month(s) that insufficient price data are collected.
There were no indexes where the index value and percent changes needed to be suppressed in May 2021.
Changes to Methods
There were no changes to estimation methodology for the release of U.S. Import and Export Price Indexes.
