Slave Prices, Geography and Insolation in 19th Century African-American Stature
The use of height data to measure living standards is now a well-established method in the economic literature. Moreover, while much is known about 19th century black legal and material conditions, less is known about how 19th century institutional arrangements were related to black stature. Although modern blacks and whites reach similar terminal statures when brought to maturity under optimal biological conditions, 19th century African-American statures were consistently shorter than whites, indicating a uniquely 19th century phenomenon may have inhibited black stature growth. It is geography and insolation that present the most striking attribute for 19th century black stature, and greater insolation and higher slave prices are documented here to be associated with taller black statures.nineteenth century, African-American stature, slave prices, insolation, vitamin D
African-American and White Inequality in the American South: Evidence from the 19th Century Missouri State Prison
The use of height data to measure living standards is now a well-established method in economic history. Moreover, a number of core findings in the literature are widely agreed upon. There are still some populations, places, and times, however, for which anthropometric evidence remains thin. One example is 19th century African-Americans in US border states. This paper introduces a new data set from the Missouri state prison to track black and white male heights from 1829 to 1913. Where modern blacks and whites come to comparable terminal statures when brought to maturity under optimal conditions, whites were persistently taller than blacks in this Missouri prison sample. Over time, black and white adult statures remained approximately constant throughout the 19th century, while black youth stature increased considerably during the antebellum period and decreased during Reconstruction.
Demographic, Residential, and Socioeconomic Effects on the Distribution of 19th Century African-American Body Mass Index Values
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 ages when worker physical productivity declined. Throughout the late 19th and early 20th centuries, black BMIs decreased across the distribution, indicating that the 20th century increase in black BMIs did not have its origin in the 19th century. During industrialization, black BMIs were lower in Kentucky, Missouri, and urban Philadelphia.nineteenth century U.S. economic development, body mass index, 19th century race relations
Demographic, Residential, and Socioeconomic Effects on the Distribution of 19th Century White Body Mass Index Values
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 BMI quantiles continued to decrease. Late 19th and early 20th century white BMIs increased at older ages in higher quantiles and decreased in lower quantiles, indicating significant net biological disparity by age. During industrialization, white BMIs were lower in Kentucky, Missouri, and urban Philadelphia.body mass index, 19th century race relations
Nineteenth Century Black and White US Statures: The Primary Sources of Vitamin D and their Relationship with Height
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 whites by the primary sources of vitamin D production: time exposed to solar radiation, skin pigmentation, and nativity. Greater insolation (vitamin D production) is documented here to be associated with taller black and white statures, and a considerable share of the stature differential by socioeconomic status was related to insolation.socioeconomic status, vitamin D, insolation, 19th century US statures
A Quantile Approach to the Relationship between Body Mass, Wealth, and Inequality
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 whites. There was a positive relationship between 19th century BMIs and average state-level wealth, and an inverse relationship between BMI and wealth inequality. After controlling for wealth and inequality, rural agricultural farmers had greater BMI values than their urban counterparts in other occupations.BMI, wealth, inequality, and race
Black and White Labor Market Outcomes in the 19th Century American South
Modern labor studies consider the relationship between wages and biological markers. A relevant historical question is the relationship between occupational status and biological markers. This study demonstrates that 19th century stature and BMIs were significant in Texas occupation selection; however, stature and BMIs were not significant in the decision to participate in the Southwestâs labor market. In the post-bellum south, labor markets were segregated, and white laborers were at a distinct occupational and social advantage relative to their black counterparts. It is documented here that the probability of being farmers and unskilled workers were comparable by race. However, whites had greater access to white-collar and skilled occupations.19th century US labor markets, labor force participation, stature and BMI
Geography, Insolation, and Institutional Change in 19th Century African-American andWhite Stature in Southern States
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 institutional change. Although modern blacks and whites reach similar terminal statures when brought to maturity under similar biological conditions, 19thcentury African-American statures in Southern states were consistently shorter than whites, indicating a uniquely 19th century phenomenon may have influenced black stature growth. It is geography and direct sunlight (insolation) that present a striking attribute of 19th century black and white statures, and greater insolation is documented here to be associated with taller black and white statures.nineteenth century Southern black and white statures, insolation, vitamin D
Demographic, Residential, and Socioeconomic Effects on the Distribution of 19th Century US White Statures
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 19th century white statures were positively associated with direct sunlight, which is the primary source of vitamin D in mammals. Stature and insolation are associated with occupations, and workers who spent more time outdoors produced more vitamin D and grew taller. White statures also decreased throughout the 19th century, and this stature diminution is observed across the stature distribution.19th US white statures, vitamin D, solar radiation, quantile regression
Health, Wealth and Inequality: a Contribution to the Debate about the Relationship between Inequality and Health
The relationship between material inequality and health is the subject of considerable debate, and may depend on how the relationship is defined. This paper uses stature as its measure for cumulative health outcomes to illustrate that the 19th century relationship between material inequality and health was negative; greater average state wealth was associated with taller individual statures. The paper also proposes and supports a bio-spatial relationship between the environment and stature.
