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...

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...

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...

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...

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...

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...
