US Meats, Poultry, Fish, and Eggs Consumer Price Index

Understanding US Meats, Poultry, Fish, and Eggs Consumer Price Index

The meats, poultry, fish, and eggs Consumer Price Index (CPI) aggregates retail prices of primary animal protein sources purchased for home consumption. Component branches exhibit vastly different supply cycles yet are combined according to consumer expenditure weights. The metric excludes total food, does not measure meal prices at service establishments, and is not identical to livestock or fishery prices at the production stage. Relative to the food at home index, this is a narrower segment and typically exhibits higher volatility.

Caution is warranted regarding month-on-month changes because disease outbreaks, weather, fishing seasons, feed costs, and promotional campaigns can generate abrupt fluctuations. Year-on-year comparisons help smooth out the seasonal component, whereas month-on-month comparisons reveal how rapidly a supply shock is forming. Items do not carry equal weights, meaning increases in eggs or fish cannot be used directly to deduce the entire group. Counter prices also react with a lag to input prices due to inventories, contracts, and processing stages. Shifting consumption structures also lead to updated weights.
