Disparities in Height and Urban Social Stratification in the First Half of the 20th Century in Madrid (Spain).

Adult height is the most commonly used biological indicator to evaluate material and emotional conditions in which people grew up, allowing the analysis of secular trends associated with socio-economic change as well as of social inequalities among human populations. There is a lack of studies on both aspects regarding urban populations. Our study evaluates the secular trends and the disparities in height of conscripts born between 1915 and 1953 and called-up at the age of 21 between 1936 and 1969, living in districts with low versus middle and high socio-economic conditions, in the city of Madrid, Spain.
