In this episode, we meet Prof. Eric Schneider to discuss the use of data on heights in economic history as a measure of well-being. Eric discusses his use of the crew records on a British ship (in operation for over a century) and what such sources can reveal about human growth patterns over longer time horizons- are they simply a function of income or is there more to the picture? We also hear about variation across countries and note some dramatic changes in human growth patterns over the last century. Finally, Eric talks about the importance of revisiting old height data with new insights from the medical literature and applies this framework to the existing data on slave children.
