And because fertility rates fell across that very same period that life expectancy was going up, that pyramid that has always represented the distribution of age in the population, with many young ones at the bottom winnowed to a tiny peak of older people who make it and survive to old age, is being reshaped into a rectangle.
Zato što su stope plodnosti pale tokom samog perioda kada je očekivani životni vijek rastao, ta piramida koja je uvijek predstavljala distribuciju godina u populaciji s mnogo mladih na dnu obavijenih malim šiljkom starijih ljudi koji su uspjeli i preživjeli do starosti je preoblikovana u pravokutnik.
