The use of height data to measure living standards is now a well-established method in the economic literature, and heights are related with vitamin D. Although African-Americans and whites have the genetic ability to reach similar terminal statures, 19th century blacks were consistently shorter...

Using a source of 19th century US state prison records, this study addresses European-American stature variation. The most commonly cited sources for stature variation are diets, disease, and work effort. However, vitamin D is also vital in human statures and health. This paper demonstrates that...

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...

By using a new source of 19th century Texas state prison records, the present study contrasts the biological living conditions of comparable blacks and whites in the American South between the Civil War and Reconstruction. White stature exceeded black stature. Between 1850 and 1870, black...

Little research exists on the body mass index values of 19th century Americans of European descent. Using a new BMI data set and robust statistics, between 1860 and 1880, BMIs decreased across the distribution; however, after 1880, BMIs in the highest quantiles increased, while those in lower...

Much has been written about 19th century African American and white statures and body mass index values. However, little is known about their physical activity and calories required to sustain height and weight. This paper considers two alternative measures for biological conditions that address...

Little work has been done on the biological conditions for the US Central Plains. Throughout the late 19th and early 20th centuries, black and white statures in Nebraska increased with economic development, indicating that biological conditions improved as Nebraska's output market and...

Much has been written about the modern obesity epidemic, and historical BMIs are low compared to their modern counterparts. However, interpreting BMI variation is difficult because BMIs increase when weight increases or when stature decreases, and the two have different implications for human...

Using data from late 19th and early 20th century US prisons, this study considers how black and mulatto basal metabolic rates and calories varied with economic development. During the 19th century, black physical activity and net nutrition declined during the late 19th and early 20th centuries...
