The biological standard of living in 19th century Mexico and in the American West

During the mid-19th century, the United States acquired Texas and large parts of Mexican territory with the vast Mexican-born population. This paper considers the biological standard of living of the part of this population that was incarcerated in American prisons. We use their physical stature as a proxy for their biological welfare. These data confirm earlier results which showed that adult heights tended to stagnate in Mexico during the late-19th century despite considerable social and political turmoil. While there is some evidence of a decline in height among youth, the decline is slight (< 1 cm). As in other 19th century samples, farmers were the tallest. Americans were taller than Mexican prisoners by about 2 cm. (C) 2005 Elsevier B.V. All rights reserved.
