Longer view

An alternative YoY calculation using a 13-month rolling window, which smooths seasonal effects slightly differently than the standard 12-month measure.

Decomposition

Multiplicative Seasonal Decomposition

CPI broken into its observed, trend, seasonal, and residual components using multiplicative decomposition — separating the calendar rhythm from the underlying price signal.

Decomposition Residuals (1960–Present)

What remains after removing trend and seasonal components — large residuals correspond to supply shocks, policy discontinuities, and structural breaks.
