This is an update of a similar post from 2015. The UN projections have changed but only by small numbers. The main observations are the same as six years ago (click table to enlarge in a new tab).
The working age population (WAP, those aged 15 to 64) of sub-Saharan Africa continues to grow rapidly. It has more than doubled since 1990 from 252 million to 609 million, and is expected to more than double again by 2050 to 1.3 billion. If the reality turns out to be anywhere near these projections, it will be a significant challenge for African economies to absorb and to employ productively this enormous amount of new human energy.
India faces a similar challenge with its WAP growing from 928 million now to 1.1 billion in 2050. Though daunting, this represents a slowdown in the rate of growth from the previous thirty-year span 1990-2020.
The WAP of Europe, China and Japan have already peaked and will be declining for the rest of the century, per UN projections. Europe’s decline from near 500 million in 2005 to a projected 407 million by 2050 is mainly due to eastern and southern Europe. The WAP of France and the United Kingdom will flatline to 2050 while those of Germany and Russia decline.
In the United States, the steady growth in the WAP between 1960 and 2005 combined with a falling dependency ratio to fuel strong economic conditions. Growth in the WAP is expected to be more muted in the decades ahead.
Compared to the late 20th century and the first decades of this century, the future growth in the WAP will taper off or even turn negative in several regions and countries. Sub-Saharan Africa stands out as the exception that will maintain strong WAP momentum through at least 2050.
“For some people, risk is scary and dangerous, and means peril and loss. For others, it means risk assets and they have to pile on because they just see the upside. But risk is actually value-neutral. It is important to be aware of the bias that you bring to things. Do you see both sides and do you weigh them? Or are you likely to overweigh the downside or overweigh the upside?” ________ Michele Wucker
We all have an ambivalent attitude towards risk. In 1850, a young Emily Dickinson wrote to her friend Abiah Root “the shore is safer, Abiah, but I love to buffet the sea. I can count the bitter wrecks here in these pleasant waters, and hear the murmuring winds, but oh, I love the danger!”
In her new book You Are What You Risk, author and strategist Michele Wucker codifies this ambivalence to risk. In this podcast with Sami, Michele explains the concepts of “risk fingerprint” and “personal risk portfolio”, among others.

Sinclair Lewis called it “the sedate pomposity of the commercialist”. Now it has spread to many parts of society, not always in its sedate form.
Back in our final days as architecture students in Austin, our class had a farewell gathering with a professor who had been a valued mentor to several of us. As was habitual on such occasions, the professor was discussing with us the work of various architects when the subject of a newly-constructed building came up.
“I hate that building”, one classmate said flatly.
After an awkward silence, the professor mocked: “you mean, strongly dislike?” Off guard, the offending party protested that his use of the word was innocuous then and there. The professor conceded as much but explained that it was a visceral word, the kind of word that forestalls further discussion and that hardens the speaker’s and listener’s opinions. It is difficult to walk back or to change your mind from “hate”, and easier to do so from “dislike” or even from “strongly dislike”, he argued. His advice was to leave in one’s words an open path for retreat, in essence to never burn one’s rhetorical bridges.
This led to another discussion about certainty and about people who speak with certainty. The professor said that he had a reflexive dislike for certainty and that he felt a profound distrust towards people who speak with certainty. There is very little that is certain in life, he said, even among things of which we are convinced at a given point in time. Opinions change, science changes, research advances. New discoveries change our beliefs. Knowledge doesn’t just flow or evolve gradually like a river; it shifts laterally and sometimes suddenly like an earthquake.Read more
A French version of this article appears in L’Express.
Former mayor Mike Bloomberg has announced that he would spend as much as $100 million of his own money to help Vice-President Biden prevail in Florida on Election Day. This underscores once again the importance of Florida in this and every presidential contest.
Florida has a good track record of picking the winner in a presidential election. With the messy 2000 contest between George W. Bush and Al Gore, the state gained prominence as the ultimate prize and must-win battleground. To be sure, it is not a perfect track record, given that Florida favored George H. W. Bush in 1992 and Richard Nixon in 1960 over winners Bill Clinton and John Kennedy. If you go to earlier times, you also find that Floridians misfired with John Davis and James Cox in 1924 and 1920, two unknowns today except among aficionados of electoral history. But in sum, four misses out of 25 elections over a century can indeed be called a strong track record.
The stakes are high in 2020 given the state’s 29 Electoral College votes and the tightness of the race according to the polls. Vice President Biden is now nominally ahead by 1 to 3%, an insignificant gap that can easily close or widen in the remaining days of the campaign, depending on a slew of factors, not least the performance of each candidate in the upcoming debates.Read more
What are the odds that the coronavirus will recede on its own during the spring because of warmer temperatures or a higher ultraviolet (UV) index? This has been a question from the beginning.
There has been some research in support of the idea that the warmer season would force the virus to retreat. And there has been other research that concluded that the virus would retreat but not disappear, that it would survive in the southern hemisphere and that it could then stage a comeback in the northern hemisphere in the fall when cooler temperatures return.
Looking at the United States state by state, we find little correlation between the number of deaths per capita and the UV index. For example, Wisconsin with a UV index of 4 in March has so far suffered 25 deaths per million inhabitants, but Rhode Island also with a UV index of 4 saw as many as 60 deaths per million. At one extreme, New York, New Jersey, Michigan, Connecticut and Massachusetts, all with a March UV index of 4, had over 100 deaths per million. At the other extreme, South Dakota also with a March UV index of 4 had only 7 deaths per million. (All deaths figures are as of 12th April 2020 per Worldometer). Read more
There is plenty that we do not know about the coronavirus. But let us take stock of the things that we do know for sure, and of some other things that we will soon know.
By now, a child understands exponential growth. If you start with one apple on March 1st and double every three days, you will have a thousand apples on March 31st and a million on April 30th.
But in the real world, not the abstract world of math, there are constraints on that growth. Doubling your apples every three days is feasible for a month or so because you can probably find a thousand apples and also find a place to store them. But it would be more difficult to find, transport and store a million apples, unless you are willing to pack a six car garage with apples from floor to ceiling (accurate math). If you did, most of them would rot and your neighbors would call for psychiatric help, two other constraints on unbridled exponentiality. Read more
