You are right. The article is saying that the population will peak in 2050, although its headline, which is gibberish, mentions the growth rate peaking, which is what u/ExoticSalamander4 was talking about.

Many years ago I heard a TV reporter say that inflation was accelerating at an increasing rate of speed. I'm not sure how many derivatives that is, but almost certainly more than intended.

Relevant funny Wikipedia excerpt:

"When campaigning for a second term in office, U.S. President Richard Nixon announced that the rate of increase of inflation was decreasing, which has been noted as "the first time a sitting president used the third derivative to advance his case for reelection."[2] Since inflation is itself a derivative—the rate at which the purchasing power of money decreases—then the rate of increase of inflation is the derivative of inflation, opposite in sign to the second time derivative of the purchasing power of money. Stating that a function is decreasing is equivalent to stating that its derivative is negative, so Nixon's statement is that the second derivative of inflation is negative, and so the third derivative of purchasing power is positive.

Nixon's statement allowed for the rate of inflation to increase, however, so his statement was not as indicative of stable prices as it sounds."
