The recent inflation surge prompted renewed assessments of inflation inequality. Examinations of inflation by income or other demographic groups point to a shrinking or stable inflation gap between high- and low-income households in 2022.

I show that aggregating households into demographic groups not only masks the majority of heterogeneity, but fails to capture important dynamics between that heterogeneity and the level of inflation.
