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...

The use of height data to measure living standards is now a well-established method in the economic literature. While much is known about 19th century black legal and material conditions, less is known about how 19th century biological conditions were related to the physical environment and...

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...

Using a new source of 19th century state prison records, this study contrasts the biological living conditions of comparable US African-American and white female statures during economic development. Black and white female statures varied regionally, and white Southeastern and black Southwestern...

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...

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 research exists on late 19th and early 20th century US body mass index value differences by race, and darker complexions were associated with greater BMI values. Mulattos had greater BMI returns associated with socioeconomic characteristics, indicating that while blacks had greater BMIs...

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...
