“Society is unity in diversity”*…
In less than one year, the 2020 census will record just how much more racially diverse the nation has become, continuing the “diversity explosion” that punctuated the results of the 2010 census. While less authoritative than the once-a-decade national headcount, recently released U.S. Census Bureau estimates for 2018 make plain that racial minority populations—especially Hispanic, Asian and black Americans—continue to expand, leaving fewer parts of the country untouched by diversity…

As we delight in difference, we might recall that it was on this date in 1814 that then 35-year-old lawyer and amateur poet Francis Scott Key wrote “The Defense of Fort M’Henry,” a poem– which provided the lyrics for the U.S. national anthem– in which he described the bombardment of Fort McHenry by British ships of the Royal Navy in Baltimore Harbor during the Battle of Baltimore in the War of 1812. Key was inspired by the large U.S. flag, with 15 stars and 15 stripes, known as the Star-Spangled Banner, flying triumphantly above the fort during the U.S. victory.
Indeed, he wrote lyrics beyond those most of us have heard: a pro-slavery, anti-abolitionist campaigner, Key wrote a (now mostly omitted) third stanza that promises that “No refuge could save the hireling and slave / From the terror of flight, or the gloom of the grave.”
“What goes up must come down”*…
For most of human history, the world’s population grew so slowly that for most people alive, it would have felt static. Between the year 1 and 1700, the human population went from about 200 million to about 600 million; by 1800, it had barely hit one billion. Then, the population exploded, first in the United Kingdom and the United States, next in much of the rest of Europe, and eventually in Asia. By the late 1920s, it had hit two billion. It reached three billion around 1960 and then four billion around 1975. It has nearly doubled since then. There are now some 7.6 billion people living on the planet.
Just as much of the world has come to see rapid population growth as normal and expected, the trends are shifting again, this time into reverse. Most parts of the world are witnessing sharp and sudden contractions in either birthrates or absolute population. The only thing preventing the population in many countries from shrinking more quickly is that death rates are also falling, because people everywhere are living longer. These oscillations are not easy for any society to manage…

As we ponder population, we might recall that it was on this date in 1845 that the first issue of Scientific American was published. Founded as a weekly by painter and inventor Rufus M. Porter, as a four-page weekly newspaper, its early emphasis was on a broad range of inventions ranging from perpetual motion machines, through an 1860 device for buoying vessels (created by Abraham Lincoln), to the universal joint which now can be found in nearly every automobile manufactured. It became the somewhat more substantial monthly publication that we know and love when,in 1948, three partners (publisher Gerard Piel, editor Dennis Flanagan, and general manager Donald H. Miller, Jr) who were planning on starting a new popular science magazine, to be called The Sciences, purchased the assets of the then century-old Scientific American instead and put its name on the designs they had created for their new magazine.

“I long, as does every human being, to be at home wherever I find myself”*…
So … what if everyone went back where they came from?
The always-illuminating Nathan Yau, of Flowing Data, demonstrates that in the U.S., almost everyone comes from somewhere else. See his explanation at “If We All Left to ‘Go Back Where We Came From’.”

As we contemplate commonality, we might recall that it was on this date in 1648 that Mehmed IV became Sultan of the Ottoman Empire… at the age of 6 (as a result of his father’s overthrow). He went on to become the second longest reigning sultan in Ottoman history (after Suleiman the Magnificent). Under his reign the empire reached the height of its territorial expansion in Europe.

“A hero is someone who has given his or her life to something bigger than oneself”*…
Elbertie Foudray did well playing an unfair game.
Between 1920 and 1945, she became one of the United States’ most important actuaries. World class experts scheduled meetings to talk statistics with her. The life insurance industry, the developing welfare system, and the first generation of American state planners all relied on her research. Foudray’s reputation grew. And her salary also grew too. Still she did not earn even half as much as she should have and despite two decades of celebrated service and significant responsibility, Foudray couldn’t escape the ranks of the “assistant” class…
In many ways, Foudray resembles one of the “hidden figures,” whose stories Margot Lee Shetterly so wonderfully told and director Theodore Melfi brought, with delightful verve, to a theater near you. Even though Foudray’s whiteness extended her privileges not available to Dorothy Vaughan, Mary Jackson, or Katherine Johnson, like them she made crucial contributions to a major national project only to have those contributions forgotten…
America’s elite population researchers trusted Foudray, identifying her with her tables. They trusted “the Foudray life tables,” which appeared in multiple / key / works of interwar demography. When Foudray (rather typically, it seems) challenged some assumptions made in calculations by Pascal K. Whelpton—the most important population forecaster of the day—he responded that he “surely will see Miss Foudray the first time I am in Washington…” He took her seriously…

As we give credit where credit is due, we might recall that it was on this date in 1876 that Lt. Col. George Armstrong Custer observed “Indian activity” and prepared his troops for the engagement that unfolded the following two days– the most prominent battle in the Great Sioux War of 1876, in which Lakota, Northern Cheyenne, and Arapaho warriors annihilated five companies of the U.S. 7th Cavalry led by Custer. Known by its Native American participants as the “Battle of the Greasy Grass,” and by most American history books as the “Battle of Little Big Horn,” it culminated with “Custer’s Last Stand” on June 26, 1876.

“Demography is destiny”*…
Every time a man ejaculates, he produces somewhere between 40 million and 1.2 billion sperm. About half of those tiny swimmers carry an X chromosome and about half carry a Y. So you’d think that the odds that one or the other would be the first to fertilize an egg would be about the same as a coin flip. And yet, for as long as people have been keeping records, nature shows a different, dependable pattern: For every 100 babies born biologically female, 105 come out biologically male. Scientists have speculated this mysteriously male-biased sex ratio is evolution’s way of evening things out, since females consistently outlive their XY-counterparts—for every man that reaches the age of 100, four women have also joined the Century Club.
This biological maxim has been so drilled into the heads of demographers—the researchers responsible for keeping tabs on how many people there are on the planet—that most don’t think twice before plugging it into any projections they’re making about how populations will change in the future. But a massive effort to catalog the sex ratios at birth, for the first time, for every country, shows that’s not such a smart strategy after all.
“For so long people just took that number for granted,” says Fengqing Chao, a public health researcher at the Institute of Policy Studies in Singapore. “But no one had ever gone to the trouble of pulling all this information together to get accurate estimates of this fundamental metric.” Chao led the five-year project, combing through decades of census data, national survey responses, and birth records to build models that could estimate national sex ratios across time. In doing so, she and her collaborators at the United Nations discovered that in most regions of the world, sex ratios diverge significantly from the historical norm. Across a dozen countries, the chasm amounts to 23.1 million missing female births since 1970. The results, published in the Proceedings of the National Academy of Sciences, provide an unprecedented look at how societal values can skew the laws of nature…
The Case of the Gone Girls (and what it might mean): “First big survey of births shows millions of missing women.”

As we become boosters for balance, we might send nurturing birthday greetings to Benjamin McLane Spock; he was born on this date in 1903. The first pediatrician to study psychoanalysis to try to understand children’s needs and family dynamics, he collected his findings in a 1946 book, The Common Sense Book of Baby and Child Care, which was criticized in some academic circles as being too reliant on anecdotal evidence, and in some conservative circles for promoting (what Norman Vincent Peale and others called) “permissiveness” by parents. Despite that push-back, it became one of the best-selling volumes in history, having sold at the time of Spock’s death in 1998 over 50 million copies in 40 languages.
