Journal Article
Demography (1979) 16 (3): 377–388.
Published: 01 August 1979
...Gary H. McClelland Abstract The two methods commonly used to assess the effect of sex preferences on fertility are inadequate to the task. Parity progression ratio analyses suffer from logical problems stemming from the heterogeneity of sex preferences and the riskiness of fertility decisions...

...Griffith Feeney Abstract Taiwan’s decline in fertility is studied by using period parity progression ratios. Levels of marriage and motherhood are found to have been high and essentially constant though the late 1980s, suggesting that the decline has been due almost entirely to declines in second...

Results show that the cohorts increased and decreased their age at first birth, birth intervals...

... among these variables. Two hypotheses are formulated governing the relationship of the closed and open birth intervals with the fecundability distribution of fertile women, and Parity Progression Ratios which are largely influenced by the proportion of women becoming sterile after each parity. The data...

.... This distribution is derived under three sets of assumptions on the rate of occurrence of births of any specified order in the past and the parity progression ratio (PPR: the probability that a woman who has given birth to her ith child will ever proceed to the [i+1] th child in her reproductive life). Explicit...

...Thomas W. Pullum; Lucky M. Tedrow; Jerald R. Herting Abstract Procedures are developed to allocate the change in mean fertility to the change in specific parities or groups of parities. One procedure uses the proportion at each parity and another uses parity progression ratios. Both are based...

To detect trends in these parameters, estimates are made of them for the U. S...

...Douglas C. Ewbank Abstract A decomposition of age-specific marital fertility rates into indices related to spacing and stopping is developed by using Coale and Trussell’s indices and the first few parity progression ratios. This approach leads to estimates of the mean birth interval among low...

...) trends in the total fertility rate and its components. For the methodology to be applicable, the total fertility rate (TFR) must be calculated from parity progression ratios (PPRs). The components of the TFR are PPRs, the total marital fertility rate (TMFR), and the TFR itself as measures of the quantum...

Little evidence of fertility control within marriage is found for the very oldest women in the sample, but analysis of parity progression ratios indicates that some control had emerged...

.... The method is applied to data from Colombia. It is found that the mortality rate differs across individuals and is correlated with fertility. Such conditions vitiate the use of birth intervals and parity progression ratios yet can be dealt with using the new method. On average each death produces 0.2 new...

The results further indicate that parity progression ratio measures inherently underestimate the effect of sex preferences on individual fertility because they incorrectly assume that sex preferences (a) are homogeneous within the population and (b) can only...
