Consumer Price Index

Impact of the coronavirus (COVID-19) pandemic on Consumer Price Index data for January 2022

This page provides further information on the effects of the COVID-19 pandemic for the January 2022 Consumer Price Index news release.

Collection mode

Data collection for January 2022 involved almost no personal visits, so nearly all data were collected either online or through telephone interviews. An example of this is full-service restaurants; even if a restaurant was open for dine-in service, as well as open for take-out or delivery, the data collector attempted to obtain the price from the restaurant’s website or by telephone call with the respondent, rather than a personal visit.

Response rates

For some CPI market basket categories, the percentage of the sample collected in January 2022 was notably lower than the pre-pandemic average. These included gardening and lawncare services, leased cars and trucks, food from vending machines and mobile vendors, and new vehicles. There was not a lower percentage of collected rents in January 2022 compared with January 2021.

Imputation

In January 2022, the CPI continued to impute the majority of uncollected prices from collected prices within the same item and geographic area (home cell). There were no instances where the data from the previous month was imputed to the current month (carry forward).

Non-vacant units with respondents previously reporting, but not currently reporting, receive non-interview imputation for use in the CPI. Vacant units that were previously occupied by renters are also imputed for use in estimation by separate methods. Table 6 below shows a reduction in vacancy imputation performed in the current month relative to the same time in 2019.

Measures of error

The standard error of the CPI’s change can be used to construct confidence intervals to determine whether the change for a particular CPI series is significantly different from zero. Table 8 shows the 1- and 12-month standard error for selected indexes at the U.S. level.
