Recent modern life expectancy improvements rely heavily on medical intervention; however, before the mid-20th century, increased longevity was primarily the result of improved nutrition and less virulent disease environments. Moreover, 19th century health conditions varied by race, especially in...

Vitamin D is vital in all vertebrates because it allows them to absorb more calcium from their diets, contributing to stronger skeletal systems and stature growth. Using a new source of 19th century US state prison records, this study contrasts the statures of comparable African-Americans and...

Nineteenth century white US statures varied with nutrition, disease exposure, and the physical environment. An additional explanation for stature growth is vitamin D production. Vitamin D is produced internally by the synthesis of cholesterol and sunlight in the epidermis. However, studies that...

The use of height data to measure living standards is now a well-established method in economics. Nevertheless, a neglected area in historical stature studies is the relationship between stature and family size, and statures are documented here to be positively related with family size. The...

Little research has been done on the body mass index values of 19th century US African-Americans and whites. This paper uses 19th century US prison records to demonstrate that although modern BMIs have increased in the 20th century, 19th century black and white BMIs were distributed...

Little research exists on the historical relationship between BMI variation, wealth, and inequality. This study finds that 19th century US black and white BMIs were distributed symmetrically; neither wasting nor obesity was common. Nineteenth century BMI values were also greater for blacks than...

Little research exists on the body mass index values of late 19th and early 20th century African-Americans. Using a new BMI data set and robust statistics, this paper demonstrates that late 19th and early 20th century black BMI variation by age increased in their mid-30s but declined at older...

Individuals urbanize when the net benefits to urbanization exceed rural living conditions. Body mass, height, and weight are welfare measures that reflect the net difference between calories consumed and calories required for work and to withstand the physical environment. Nineteenth and early...

When traditional methods for measuring economic welfare are scarce or unreliable, heights and BMIs are now well accepted measurements that represent biological conditions during economic development. Weight, after controlling for height, is an alternative measure to BMI for current net...

When other economic measurements are scarce or unreliable, height and the body mass index (BMI) are now well accepted measures for cumulative and current net nutrition. However, as the ratio of weight to height, BMI is the ratio of current to cumulative net nutrition, therefore, does not fully...
