Using data from two national surveys (ENSA, 2000; ENSANUT, 2006) we assess the evolution of biological standards of living of the Mexican population born during the second half of the 20th century. Our results show that there was an improvement in living standards reflected in an increase in stature, but this amelioration was limited. We observe differences across socio-economic strata, across educational levels, and between men and women. Persistent structural inequality has been byproduct of a system of security and social protection that was limited, segmented and hampered the potentially positive effects of social-welfare policies. We corroborate the relatively modest improvement in heights by comparing outcomes in Mexico with other Latin American countries.

This paper offers new quantitative evidence on living standards in Bourbon America through a pioneering study of both wages and heights. Wages were not low, nor were heights short, by the international standards of the period. The living standards of Spanish Americans thus compare favourably with those of other regions of the world, including Europe. As in many parts of the West, one can observe a trend towards the deterioration of real wages in Spanish America at the end of the period. Our findings suggest that the ‘Great Divergence’ in living standards between Spanish America and the developed Western countries might have taken place mainly after independence and that currently available GDP per capita estimates might be too low.
