3. Decrease population momentum

A third important component in the effort to slow population growth (beyond meeting unmet demand for contraception and lowering demand for large numbers of children) will be to take steps to decrease momentum in population growth. Momentum given by age structures is estimated to be responsible for nearly half of the new population growth in developing areas of the world that have "triangular" age structures (many more young people than old people).

Methods for decreasing momentum focus on:

(1) decreasing TFR to lower than RLF for a couple of generations (long enough to diminish the "bulge" in the younger age clases;

(2) raising the average age of child bearing, and

(3) widening the interval between successive children in a family.

All of these approaches are being used at present in China, and are discussed in more detail below, where we focus on China in the discussion of patterns of change in TFR. In addition, they are discussed in the articles by Bongaarts and by the Population Reference Bureau in your assigned readings .
