The average age of mothers has been rising over time, from 30.0 in 2011 to 31.1 in 2021. Average maternal age has risen for both first-time mothers (from 28.4 years in 2011 to 29.7 in 2021) and those who have given birth previously (from 31.3 years in 2011 to 32.2 in 2021).
A range of financial factors contribute to decisions to delay parenthood, including the cost of having a child (especially childcare), attaining suitable housing and the effects on career advancement and future earnings.
Australian dads are among the oldest in the world, and we're not getting any younger. According to the Australian Bureau of Statistics' data on registered births in 2020, the median age of fathers is 33.6 years, rising from 28.5 years in 1975, when data was first collated.
Even with all the understandable talk of “windows of opportunity” and “biological clocks,” there are ways for women over 35 to make motherhood a reality. Infertility treatments can be difficult and expensive, but fertility specialists can talk with you about options. Age is less of a limitation than it used to be.
If you are thinking about having a baby in your late thirties or early forties, you are not alone. Women ages 35-45 are increasingly becoming first-time moms. And most healthy women in this age group have healthy pregnancies, births and babies.
The risks of miscarriage and stillbirth are higher in people who are older than 35. Also, multiple pregnancy is more common when you are older. As the ovaries age, they are more likely to release more than one egg each month. Some fertility treatments also increase the chance of a multiple pregnancy.
While delivering at age 35 and older is officially considered “advanced maternal age,” Dr. Kalish notes that in reality, there's no “magic number” for being at-risk for complications. “A healthy 38-year-old could have an easier pregnancy than a 20-year-old who has multiple medical issues,” Dr. Kalish says.
Advanced maternal age describes a pregnancy where the birthing person is older than 35. Pregnant people over age 35 are more at risk for complications like miscarriage, congenital disorders and high blood pressure. Screening tests can help detect certain congenital disorders.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
But their mums and dads might be getting impatient with them, as baby boomers believe 30 is the ideal age to get married, with kids following the next year. On average, Australians want to enter their first serious relationship at 27, meet 'the one' at 31 and have kids at 34.
The study, published 30 August in Human Reproduction , used a federal repository of nearly 170 million birth records to find that the average dad is now 30.9 years old at their child's birth—and that 9% of newborns' fathers are at least 40 years old.
Men can produce sperm from puberty to a ripe old age and continue to father children as long as they do so. Women, on the other hand, have a limited fertile window. Past 51 – the average age of menopause – they cease to release any eggs and become infertile. Both men and women are delaying having children.
The scientists also note that at the age of 35, the proportion of sperm carrying an X chromosome also seems to increase, meaning older dads are more likely to have daughters. In human reproduction, the Y chromosome is responsible for making a male child.
Advantages of getting pregnant in your 30s
You may have a higher income and more financial security because you've had more time to establish your career. Studies have found that women who became first-time moms at or after age 33 have greater odds of living to age 95 (compared to younger moms).
Down Syndrome rates increased over time among individuals who identify as Black, Hispanic, or AIAN, but not among white or Asian individuals. Whether accessing and navigating changes in Down syndrome testing is contributing to these disparities in outcomes needs further study.
Currently, Ireland tops the countries with the highest rate of Down syndrome prevalence, as its incidence of the syndrome is reported to be 27.5 per 10,000 live births.
The average intelligence quotient (IQ) of children with DS is around 50, ranging between 30 and 70. Remarkably, a small number of patients have a profound degree of ID, whereas others have a mild degree despite the absence of any genetic, cultural or familial favoring or disfavoring causes.
So as you get older, you have fewer and fewer eggs, and the eggs you have aren't easily fertilized by a man's sperm. All this makes it harder for you to get pregnant. If you're older than 35 and have been trying for 6 months to get pregnant, tell your health care provider.
Women who become pregnant in their 30s and early 40s can have safe, healthy pregnancies, says Ellie Ragsdale, MD, director of fetal intervention at UH Cleveland Medical Center. But they do face a higher risk of some problems.
Women over age 35 take longer to conceive – The average time it takes a couple over 35 to conceive is 1-2 years, so try to remain positive if you do not become pregnant immediately.
Not optimal, but not selfish either
The point here is to look at some of the things which people say are selfish and realize that, while it may not be the “optimal conceiving time” there are plenty of reasons to have a child over forty and those reasons are not by definition selfish.
