This paper explores the relationship between the physical stature of Colombians born during the 20 th century and several socioeconomic variables.Using a dataset of more than 225,000 individuals built from judicial background certificates, we find an important increase in the stature of the population: the average height of women increased 4.1 centimeters and that of men increased 5.7 centimeters.Econometric results suggest important differences in the individual's stature according to gender, level of education, occupation, and place and date of birth.Similarly, the disease environment and access to public services significantly affect people's height.We find that departmental average height disparities decreased and the gap across regions closed throughout the century.
