... in Santiago, Chile. The methodology that was designed to study these changes through the pregnancy history method is described, and variations in the fertility rate by age group (ASFR), the general fertility rate (GFR), and the total fertility rate (TFR) during the period 1964–66, the year in which...

First, we fitted dummy-variable regression models to monthly birth data from 1990 to 1999 in metropolitan counties. We used birth counts to frame the problem and general fertility rates to address...

As an application, we combine panel survey data and birth registration data to estimate annual birth probabilities by parity.

Regional differences in birth measures (crude and general rates) were found to widen between 1950 and 1970 despite a decline in fertility at the national level and a narrowing of regional differences in important socioeconomicvariables like income...

... in the agegroups 20-24 years and 25-29 years can beused for approximate evaluations of both of these parameters. While estimates of a, and m, are sufficient to generate a relativedistribution of age-specific fertility rates, actual values can be obtained if, in addi- tion, the annual number of births is either...

... of the limited scope of this ar- ticle, we shall restrict ourselves to esti- mates of fertility in forms of birth rate only. This can then be easily translated, by means of certain models, into such in- dices as a general fertility rate, a gross reproduction rate, or a total fertility rate. METHODS...

The fertility rates stabilize with time, and the common intrinsic rates of growth for the two sexes are found to lie in the interval generated...

..., they determined the level of the black general fertility rate at the beginning of the transition (1875-1880) and at its culmination (1935-1940). The difference between the two rates represents the total observed reduction in fertility during the transition. It is assumed that fertility was not influenced by VD...

In operationalizing fertility, the studies have employed a variety of meas- ures such as the crude birth rate, the gross reproduction rate, the child-woman ratio, the general fertility rate, and age- specific female fertility. Some of the measures such as the gross reproduction rate and age-specific female fertility...
