| But what would happen over the next few decades to bring that about: A decrease in the birthrate? |
| The decline of the birthrate then was confined entirely to the legitimate births. |
| It has a birthrate of about 4.2 children per family, compared to Canada's 1.6 per family currently. |
| Where enrolment has fallen, the decrease is due primarily to rural to urban migration, but also, to some extent, to a falling birthrate. |
| Greater life expectancy in conjunction with a falling birthrate is leading to appreciable growth in the percentage of elderly persons in society. |
| Such an uneven birthrate makes it hard for scientists to determine if right whales are producing enough calves to maintain the species. |
