Rethinking the Fertility Transition in Rural Aragón (Spain) Using Height Data

Height and political activism in rural Aragón (Spain) during the 20th century. A new perspective using individual-level data

This article explores the relationship between the political leanings of more than 1000 men born in the 1870-1970 s in 11 rural Aragonese villages and their biological well-being during childhood and adolescence, proxied by height. The aim is to test whether an individual was more likely to be left-wing if his level of biological well-being was lower and, therefore, with more incentives to fight against the social inequality that had negatively affected his family. Our results confirm that, for most of the study period, there was a strong relationship between shorter height and political activism1 in left-wing parties and organizations.

The effect of height on family formation in rural Spain, birth-cohorts 1835-1975

This article examines the relationship between the height of adult males and marital outcomes, including likelihood of marrying, age at marriage, and marital fertility, in rural Spain. For this analysis, a sample of 4,501 men born between 1835 and 1975 living in 14 villages in northeastern Spain was taken. Previous research has shown that shorter individuals are less likely to marry. However, it is still disputed whether differences exist in the timing of marrying based on height, and little attention has been paid to the effect(s) of height on offspring. Family data were obtained from parish records and interviews with individuals and their families, while height data were obtained from military records, with individuals in Spain being conscripted at the age of 21 years. The data were linked according to nominative criteria using family reconstitution methods. The results confirm that shorter individuals were less likely to marry. Individuals of medium and medium-high height were the first to marry, with a small gap between them and shorter individuals. With regard to marital fertility, no difference in terms of average fertility by height were found, but there were small differences in timing of childbirth, possibly as a result of delayed marriage.
