MARQUEZ MORANCHEL, Cinthia. Inflation Inequality in Mexico, 2015-2023. Inv. Econ [online]. 2025, vol.84, n.331, pp.40-64.  Epub Aug 29, 2025. ISSN 0185-1667.  https://doi.org/10.22201/fe.01851667p.2025.331.90415.

The objective of this research is to analyze, at a national level, inflation per household by income deciles and by socioeconomic characteristics for the period 2015-2023. The methodology is based on the estimation of democratic consumer price indices that are characterized by maintaining the same price structure of the National Consumer Price Index (NCPI) with an expenditure weighting that gives equal weight to each household. The heterogeneity of inflation is substantial; households with more members, in rural areas, renters and with a man as head of household, indigenous, with low education and without affiliation to a health institution face higher inflation, reflecting the diversity of household spending patterns and income differences. The inequality of inflation is expressed in an accumulated manner in poor households, which is 6.5% higher than in rich households.

Keywords : Inflation; households; socioeconomic inequality; household expenditure; spending pattern; C43; C80; D10; D12; D31; E31.
