FERTILITY QUANTUM AND TEMPO WITH CUBIC AGE-SPECIFIC BIRTH RATES

Fertility quantum and tempo with cubic age-specific birth rates

OBJECTIVE: To demonstrate the analytical value of a cubic parameterization of the age curve of fertility and to explore its features, especially its usefulness in separating fertility read more level and fertility timing.METHODS: Using mathematical analysis, the cubic fertility curve is derived and examined in both continuous and discrete forms.RES
