La metodología se basa en la estimación de índices de precios al consumidor democráticos que se caracterizan por mantener la misma estructura de precios del Índice Nacional de Precios al Consumidor (INPC) con un ponderador de gasto que otorga igual peso a cada hogar. La heterogeneidad de la inflación es sustancial, los hogares con más integrantes, en zonas rurales, arrendatarios y con un hombre como jefe del hogar, indígena, con baja educación y sin afiliación a una institución de salud enfrentan una mayor inflación, reflejo de la diversidad del patrón de gasto de los hogares y las diferencias del ingreso. La desigualdad de la inflación se expresa de forma acumulada en los hogares pobres 6.5% superior a la de los ricos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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.]]></p></abstract>
