This is a multiyear ongoing project on inflation inequality with Jon Hartley supported and distributed by the Foundation for Research on Equal Opportunity (FREOPP). Our goal is to give academics and policymakers access to real-time inflation inequality indices across nine Census divisions and the whole nation across multiple demographic groups. Our time series starts in 1978. In 2022, we published a white paper with FREOPP, Inflation's Compounding Impact on the Poor, which explored inflation inequality across the income distribution at the national level. Our data and code were released to the public in April 2022. In May 2024, we will begin releasing monthly updates and publish a short report on geographic inflation inequality. Below, we have links to our data, a companion which consolidates and adds academic flavor to the FREOPP reports, and the original reports.
