Genotype × cohort interaction on completed fertility and age at first birth.
Microevolutionary projections use empirical estimates of genetic covariation between physical or psychological phenotypes and reproductive success to forecast changes in the population distributions of those phenotypes over time. The validity of these projections depends on relatively consistent heritabilities of fertility-relevant outcomes and consistent genetic covariation between fertility a...

By assessing associations for both genders, we were able to investigate biological versus social and behavioural explanations from early life through to adulthood. METHODS Multiply-imputed data on more than 7600 men and women of a British birth cohort s...
متن کاملEffect of education on age at first birth in Semnan, Hormozgan, Kohkiloye and Booir Ahmad provinces, Iran
Introduction: Iran experienced a dramatic fertility decline during recent decades. There was also an indication of a shift towards later childbearing from 2000. Past research on fertility has shown that the education variable is the most important determinant of fertility behaviors. However, the impact of education on fertility timing in Iran has been less considered. Methods: In a cross secti...
متن کاملRising Dispersion in Age at First Birth in Europe: Is It Related to Fertility Postponement?
This paper examines the dispersion of fertility across age and time which has rarely been studied. Using data from the Human Fertility Database, we examine fertility age schedules by looking at standard deviations in age at first births in European countries at different stages of fertility postponement. The standard deviation at first birth remained overall constant during the start of fertili...
