Published: 01 May 1970
...N. Krishnan Namboodiri Abstract A method to compare fertility sequences, each of which represents a cyclical fluctuation around an underlying trend, is presented. Each fertility sequence is viewed as composed of a time trend in childspacing pattern and a corresponding trend in terminal fertility...

..., but in populations practicing birth control the natural fertility schedule is disguised by the marital fertility rates in those age intervals in which control is exercised, the marital fertility rates being below the natural rates. This paper elaborates a method for estimating the natural fertility schedules...

... of the fertility schedule to change at a constant annual rate. Because annual changes in the shape of the fertility schedules often are approximately constant except in abnormal conditions, the Bongaarts-Feeney (B-F) method is generally robust for producing reasonable estimates of the adjusted TFR(t). The adjusted...

Moreover, new estimates of white marital fertility, based on “own-children” methods, suggest that the decline in marital fertility...

About one-half are in favor of abortion and indicate that they would use it if no other method were available and abortion were legalized.
