This November the BBC reported on a dramatic study, published by The Lancet, which told us that falls in the fertility rate of nearly half of all countries have resulted in insufficient births per fertile woman to maintain their population. The information was described as a “huge surprise”. Not to Catholic Herald readers, of course, since this column described the situation, its gravity and the likely consequences back in Feb­ruary 2015. And perhaps the headline – “‘Remarkable’ decline in fertility rates” – over-egged the drama because in fact the fertility rates of well-to-do countries are very low, while the rates of poor countries are very high.
