All values come directly from World Bank (FP.CPI.TOTL.ZG). We do not modify, smooth, or interpolate published values.
Global consumer price inflation rate, percent change year-over-year. Aggregated across all World Bank member countries. Useful context for comparing domestic inflation to the global environment.
Annual — we refresh daily; most recent value typically lags 1-2 years on upstream.
We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
