Generated from Dec 2022's observations.
As of December 2022, the Basket Index for a US family of 4 sits at 117.7 — meaning the cost of a standard household basket has risen 8.1% versus a year ago and is down 1.04% from the previous month.
Most of the move comes from rent of primary residence, electricity (residential), eggs (grade a, large) and chicken (whole, fresh). Together these items account for roughly 43% of the year-over-year basket cost change.
Offsetting the increases: gasoline (regular unleaded) (-2.9%) is cheaper than a year ago.
Inflation is rarely caused by one thing. Energy prices feed into food production and shipping; rent moves with housing supply and interest rates; and grocery prices respond to supply shocks, weather, and demand patterns. Basket Index does not claim causality — it tracks the prices households actually face, and lets you see which categories are pulling the basket up.
Year-over-year change for each item, ranked by contribution to the basket move.
Items down year-over-year, helping offset the rise.
