This article adapts a multidimensional index of the well-being of the population in the Mexican States, based on the recommendations of the Commission on the Measurement of Economic Performance and Social Progress (CMEPSP). This study’s contributions can be summarized in three key points: (i) factor analysis of principal components is used, to allow for different weights of dimensions; (ii) consideration is given to inequality of material well-being within the population of each state, and; (iii) representative state data are considered for all dimensions. The results show that the dimensions of objective well-being have greater weights than the dimensions of subjective well-being, and that differences between weights of dimensions and indicators used are more important than their quantity or characteristics.
