The top 5 percent, on the other hand, saw an increase of 6 percent. Under the fixed 2019 bundle assumption, the bottom 90 percent saw their consumption expenditure go up by between 6.7 percent to 6.9 percent in 2021. On the other hand, lower-income households spent relatively more on energy whose prices had large increases. Higher-income households spent relatively more on services, which experienced the smallest price increases. However, because of variation in the composition of consumption bundles, we find that higher-income households had smaller percentage increases in their total expenditure. Assuming the fixed 2020 bundle, these increases change to $2,160 and $7,636 respectively. For example, the bottom 20 percent saw their total expenditure go up by $2,064 (under the fixed 2019 bundle) while the top 5 percent saw an increase of $8,326 (under the fixed 2019 bundle). Since higher-income groups had a bigger increase in expenditures in all categories, they also saw a bigger increase in total expenditure. Table 1 shows the increase in the average total expenditure by income group, both as dollars and as a percent increase. At the same time, the top income groups decreased their total expenditure by $168 for the fourth quintile, $3,331 for the 80th to 90th percentile, $4,002 dollars for the 90th to 95th percentile, and $12,175 for the top 5 percent. Comparing 2020 spending to 2019 spending, we find that the bottom three income groups increased their total expenditure by $1,499 for the bottom quintile, $518 for the second quintile, and $321 for the middle quintile. During the pandemic, spending on consumption rose for lower-income households but it decreased for higher-income households. As expected, higher-income groups had relatively higher expenditures in both years. 3 Figure 1 shows the average nominal total expenditure by households in each income group in 20. 2 Households are divided into seven income groups where the cutoffs are the 20th, 40th, 60th, 80th, 90th and 95th percentiles of the income distribution. We aggregate the survey’s expenditure items into five major categories: food, energy, shelter, commodities less food and energy commodities, and services less energy services and shelter. households spend their money and how that varies across income groups. We use the Quarterly Interview Survey for 2019 and for 2020 to find out how U.S. The Consumer Expenditure Survey (CE) is a nationwide household survey conducted by the Bureau of Labor Statistics that provides information on expenditures, income, assets and demographic characteristics of U.S. Because we hold consumption patterns fixed for this analysis, we do not account for income effects, i.e., any consumption changes due to changing purchasing power, and substitution effects, i.e., any consumption changes due to changing relative prices. It seems likely that households in 2021 may follow consumption patterns along some combination of the two, with some pandemic patterns becoming more fixed even as households return to pre-pandemic behavior. Since we do not yet have data on changing consumption patterns for 2021, we analyze the increased costs under two different assumptions: (1) that consumption patterns remained the same in 2021 as in 2020, and (2) that consumption patterns remained the same in 2021 as in 2019. In this blog, we use the Consumer Expenditure Survey and the recently released CPI to investigate how much price changes increase the expenditure for households at different income levels. These price increases do not affect all households in the same way because the consumption baskets of high-income and low-income households differ. While the one-year price increases for shelter and other services (excluding energy services and shelter) were 3.8 percent and 2.9 percent respectively, the price increase for commodities (excluding food and energy commodities) was 9.4 percent. There was also a noticeable difference between commodities and services. For example, the price of food rose by 6.1 percent compared to a year ago, while the average energy price jumped by 33.3 percent. However, the increases in price were uneven across items in the CPI basket. The overall index went up by 6.8 percent from a year ago, and this level of inflation was last seen in 1982. The CPI measures the average change over time in the prices paid by consumers for goods and services. On December 10, the Bureau of Labor Statistics released the Consumer Price Index (CPI) for November 2021.
