We assess the numeracy (age heaping) of religious minorities, particularly Jews, and other defendants of the Spanish and Portuguese Inquisitions, and compare it with the general Iberian population. Our database includes 13,000 individuals who took part in Inquisition trials, and 17,000 individuals recorded in censuses and parish registers who serve as a control group. We thoroughly discuss the representativeness of our samples for the populations we aim to capture. Our results point at a substantial numeracy advantage of the Judaism-accused over the Catholic majority. Furthermore, Catholic priests and other groups of the religious elite who were occasional targets of the Inquisition had a similarly high level of numeracy.

We assess the relationship between land inequality and human capital at the end of the early modern period, focusing on individual-level evidence from Spain. Our main finding is that land inequality had already had a significant negative effect on the formation of human capital there in the late-seventeenth and eighteenth centuries. We argue that this reflects the important role of a social structure based on farming families (as opposed to latifundia and day laborers) in the development of numeracy. This is consistent with earlier studies, which argued that farming households could (1) maintain a relatively favourable nutritional standard as a precondition for cognitive skills, (2) limit child labour and (3) encourage numeracy due to its demand by farming activities. Our results are robust, as they include several control variables and potential confounding variables.
