We reweight the consumers price index (CPI) expenditure weights every three to five years to reflect changes in household spending.
This page provides a downloadable table of CPI expenditure weights from 2024 that shows the proportion of household spending for each item in the CPI basket.
Reweighting reflects changes in household spending patterns over time due to shifts in tastes, lifestyles, and incomes, as well as the availability of goods and services for purchase. Spending patterns also respond to price changes, with households generally purchasing more of goods and services that become relatively cheaper and cutting back on those that become more expensive. For example, if apple prices rise significantly while pear prices increase only slightly, consumers are likely to buy more pears and fewer apples than before.
Expenditure weights
'Consumers price index expenditure weights: 2024' shows the percentages of expenditure weights for each CPI basket item. They represent the percentage of expenditure on each item bought for consumption purposes by households, as determined primarily by the 2022/2023 Household Expenditure Survey (which has now been replaced by the Household Income and Living Survey) and supplemented by other sources.
The Item tab includes a flag for whether the item is tradeable or non-tradeable. Tradeable goods and services are those that are influenced by foreign markets. Non-tradeable goods and services do not face foreign competition and are an indicator of domestic demand and supply conditions. However, the inputs of these goods and services can be influenced by foreign competition. Note the item 'Soft drinks (aerated)' includes both tradeable and non-tradeable components.
Our reweighting aligns with International Labour Organization (ILO) guidance to update CPI spending weights at least every five years.
