Americans, for nearly two centuries, lived as the world’s tallest human beings. Averaging 172 centimeters in the year 1750, American men towered over English and Norwegians by seven centimeters, Austrians by six, and Swedes by five. But, somehow, things changed. Young Dutchmen, once among the shortest in Europe, today lead the pack at 183 centimeters, or just over six feet tall, while Americans, who gained just four centimeters in the last 250 years, are shorter than all of them.
Steckel says that traditional measures of standard of living-gross national product or per capita income-don’t reflect the total picture because they leave out other variables such as crime, congestion, workload, or the amount of leisure time afforded to a population. Height also has a direct relationship to longevity; research suggests that the height of a child at age 12 has a direct correlation with life expectancy as an adult. Per capita income can’t make the same claim.
Steckel’s research is derived in part from historical height data recorded on slave manifests of those shipped in the coast wide trade after 1807 and military muster roles from major wars.
“Among the things we learned is that slave children were dreadfully small, among the smallest populations ever measured, but recovered substantially as teenagers,” Steckel said. "Pregnant slave women had an arduous work routine, and their children as infants had a limited rate of breast feedings. Women were back in the fields within six weeks of giving birth, and the children left behind in the nursery were receiving a contaminated, low protein diet until age 10.
How tall one becomes is a function of net nutrition during periods of growth. Average height is not adept in distinguishing between degrees of opulence, but is good at distinguishing between degrees of deprivation. In other words, it’s a measure of one’s consumption of basic needs."
In the early 1700s soldiers in the United States were the tallest in the world, attributed, most likely, to a healthy diet and an abundance of farmlands. “Americans experienced the best of the old and the new world foods at that time, and also had low population density, few epidemics, and a reasonably even distribution of wealth,” Steckel said.
Average height for Americans peaked in the 1830s, then sharply declined toward a new low in 1880 (Chart 1). “Americans lost 1-1/2 to 2 inches in height despite an improving economy and increases in income,” Steckel said. "But we also had a greater spread of communicable disease as the United States urbanized. The transportation revolution in the 1820s and '30s brought steamboats, canals, and railroads. People moved and migrated, taking disease with them: cholera, scarlet fever, whooping cough. Wealth inequality was also on the rise and the poor were more exposed by business downturns.
Things didn’t get better until the end of the century with the purification of water, removal of waste, emphasis on personal hygiene, and use of antiseptics, after which point we saw an increase of eight centimeters in height in the next three-quarters of a century."
Many Europeans, whose heights once lagged several centimeters behind Americans, caught up, eventually surpassed, and continued rising. In the United States, however, height began leveling off in the mid-1900s, and, in the last 25 years, experienced no increase at all. This is a warning, says Steckel, since the majority of growth occurs in early childhood and adolescence.

Daniel Morgan, pioneer in the use of rifles in warfare, became famous as the leader of one of the most skilled regiments of sharpshooters of the American Revolution … the family moved to Jefferson County, Virginia when young Daniel was 17. By that time, Daniel Morgan had reached full maturity. At 6’2" tall and weighing 210 pounds, he was considered a giant for his day.

Some of the more interesting results are as follows:
Slaves were almost as tall as freemen (Steckel, 1979) but slave
children were short (Steckel 1986). American slaves were taller than
Africans in Africa.
Americans were taller than Europeans already in the 18th century
(Sokoloff and Villaflor, 1982).
The propinquity to nutrients was advantageous (Komlos, 1985) and
therefore people living in underdeveloped regions were often taller than
those living in industrialized areas. This was true for Ireland v.s.
England (Mokyr and O’Grada 1994) as well as for the American south v.s.
North. (Steckel and Margo, 1983)
In cross-sectional samples heights correlate positively with
social status without exception (ceteris paribus).
