The gender gap in the biological living standard in Spain. A study based on the heights of an elite migration to Mexico, 1840-1930
利用墨西哥政府外国人登记数据，研究了1840-1930年间赴墨西哥的西班牙男女移民身高演变及性别差距，发现移民身高高于留守西班牙者，且男女身高差距从10厘米以上缩小至8-9厘米。
This paper examines the evolution of the statures of Spanish male and female migrants who entered Mexico between the mid-nineteenth and the mid-twentieth century. Using the information contained in the National Registry of Foreigners created by the Mexican government, the paper also estimates the evolution of the gap between male and female migrants' heights. The inclusion of women and their heights in the registry allows the estimation of both male and female heights and the analysis of their evolution for a group of comparable individuals. The results show that Spanish migrants to Mexico grew taller between 1840 and 1930, and also reveal their character as a highly qualified group, with heights similar to those of the Latin-American elites and considerably higher than the statures of those who remained in Spain. In the long term, the differences between men and women decreased from more than 10 cm in the cohorts born in the mid-nineteenth century, to around 8-9 centimetres in the early twentieth century, coinciding with a period of profound economic and social transformations.
