For effects associated with advanced paternal age, see.Advanced maternal age, in a broad sense, is the instance of a woman being of an older age at a stage of reproduction, although there are various definitions of specific age and stage of reproduction. The variability in definitions is in part explained by the effects of increasing age occurring as a rather than as a threshold effect.In Western, Northern, and Southern Europe, first-time mothers are on average 27 to 29 years old, up from 23 to 25 years at the start of the 1970s.
In a number of European countries (Spain), the mean age of women at first childbirth has crossed the 30 year threshold. This process is not restricted to Europe. Asia, Japan and the United States are all seeing average age at first birth on the rise, and increasingly the process is spreading to countries in the such as,. In the U.S., the average age of first childbirth was 26.6 in 2016.Advanced maternal age is associated with adverse reproductive effects such as increased risk of, and that the children have.
The corresponding is less pronounced. Contents.History Having children later was not exceptional in the past, when families were larger and women often continued bearing children until the end of their reproductive age. What is so radical about this recent transformation is that it is the age at which women give birth to their first child which is becoming comparatively high, leaving an ever more constricted window of biological opportunity for second and subsequent children, should they be desired. Unsurprisingly, high first-birth ages and high rates of birth postponement are associated with the arrival of low, and lowest-low fertility. This association has now become especially clear, since the postponement of first births in a number of countries has now continued unabated for more than three decades, and has become one of the most prominent characteristics of fertility patterns in developed societies. A variety of authors (in particular ) have argued that fertility postponement constitutes the ‘hallmark’ of what has become known as the “second demographic transition”.Others have proposed that the postponement process itself constitutes a separate 'third transition'. On this latter view, modern developed societies exhibit a kind of dual fertility pattern, with the majority of being concentrated either among very young or increasingly older mothers.
This is sometimes known as the ' of.Examples In the USA, the average age at which women bore their first child advanced from 21.4 years old in 1970 to 26.6 in 2016.The German claimed in 2015 the percentage for women with an age of at least 35 giving birth to a child was 25.9%. This figure rose from 7.6% in 1981. Possible factors that influence childbearing age There are many factors that may influence childbearing age in women, although they are mostly. For instance, older maternal age at first childbirth is associated with higher educational attainment and income.Two studies show that generous parental leave allowances in Britain encourage young motherhood and that parental-leave allowance reduces postponement in Sweden.
