Most fathers today are in their early to mid-30s, with the average (median) age increasing over time, often around 33-34 years old, though this varies slightly by country, with many first-time fathers now being older, often around 30-31, and a growing percentage having children in their 40s or beyond.
Between 1972 and 2015, the researchers found, the average paternal age at the time of an American child's birth grew from 27.4 years to 30.9 years. Asian-American dads — and in particular, Japanese- and Vietnamese-American dads — are the oldest, at 36 years of age on average.
The ages of fathers has been going up over time, with the median age of dads being 33.7 years for births registered in 2022, up from 29 for births registered in 1977.
If you're older than 35 and hoping to get pregnant, you're in good company. Many families are delaying pregnancy well into their 30s and beyond — and delivering healthy babies. Taking special care can help give your baby the best start.
Many women and birthing people who choose to have a baby after the age of 40 will have healthy pregnancies. But, some complications are more likely to develop or pre-exist if you are aged 40 or older when you conceive. The risks increase as you get older.
Key statistics
Life expectancy at birth was 81.1 years for males and 85.1 years for females in 2022–2024, reflecting no change for either males or females from the previous year (2021–2023). Life expectancy was highest in the Australian Capital Territory for both males (82.0 years) and females (85.8 years).
At 20 weeks of pregnancy, a female fetus has 6–7 million of eggs. By the time the woman is 30 years, she will have lost nearly 90% of her eggs and at the age of 40 years, only around 3% of eggs are left. Most women are no longer able to become naturally pregnant in their mid-40s.
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.
Parenting expert Sarah R. Moore says that it isn't selfish to have a baby at 40. By 40, you likely know who you are and what kind of parent you want to be, so you can raise your child with intention. However, there are health risks for both the baby and the mother, and you'll have to reassess your career priorities.
"70/30 parenting" refers to a child custody arrangement where one parent has the child for about 70% of the time (the primary parent) and the other parent has them for 30% (often weekends and some mid-week time), creating a stable "home base" while allowing the non-primary parent significant, meaningful involvement, but it also requires strong communication and coordination to manage schedules, school events, and disagreements effectively.
Older dads and fertility
Just as a woman's chance of conceiving declines after a specific number of birthdays, men's fertility also declines. If you're still in your 20s or 30s, you have a better chance of fathering a child than if you're 40 or older because, before age 40, men have higher-quality sperm.
The most common "3 Ps of Fatherhood" are Provider, Protector, and Permanence/Presence, representing a father's role in ensuring financial and emotional security, safeguarding his family, and being a consistent, steadfast presence. Other variations expand these to include Preside (leadership/guidance), Playmate, and Priest (spiritual leader), emphasizing nurturing, emotional support, and guidance for a child's development.
While parenting challenges vary, research and parent surveys often point to the middle school years (ages 12-14) as the hardest due to intense physical, emotional, and social changes, increased independence, hormonal shifts, and complex issues like peer pressure and identity formation, leading to higher parental stress and lower satisfaction compared to infants or older teens. Other difficult stages cited include the early toddler years (ages 2-3) for tantrums and assertiveness, and the early teen years (around 8-9) as puberty begins, bringing mood swings and self-consciousness.
Well, research shows the father-child relationship is an important one, In fact it can be more influential than the mother-child relationship. This is especially true for the 8-12 year old child as they try to make sense of the outside world.
In support of the widely held understanding that first babies are more likely to be born “late,” we found that deliveries go beyond 41 weeks' gestation 1.53 times more frequently among mothers with a first-time delivery compared to those who have previously delivered, confirming anecdotal wisdom.
The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions every 3 minutes, lasting 2 minutes each (or 1 minute long for some variations), for over 1 hour. It helps differentiate true labor from false labor (Braxton Hicks), signaling it's time to head to the birthing center, while subsequent pregnancies often follow the faster 5-1-1 rule.
Those women who have late menopause have babies early and often have babies without difficulty, well into their early to mid-40s, but it's rare for any population you study that women have successful pregnancies after 45 with any kind of frequency.
Jennifer Aniston underwent IVF treatments throughout her late 30s and 40s, a challenging period where she tried everything to conceive, eventually continuing into her early 50s, ultimately deciding to share her private fertility struggle years later in an interview with Allure.
Genes are not involved and there's no scientific evidence that being from a family with identical multiples has any impact on your odds of having twins. The same is not true for fraternal twins. So, having identical twins is not due to genetics. On the other hand, fraternal twins can run in families.
Proper storage of eggs can affect both quality and safety.
Store promptly in a clean refrigerator at a temperature of 40° F or below. Use a refrigerator thermometer to check. Store eggs in their original carton and use them within 3 weeks for best quality.
Certain lifestyle habits can negatively affect your physical and mental health, shortening your potential lifespan.
Australia's top three causes of death consistently include Dementia (including Alzheimer's disease), Ischaemic Heart Disease, and Chronic Lower Respiratory Diseases (like COPD), though their exact ranking can shift, with dementia often leading for women and heart disease for men, but the overall gap narrowing significantly, according to recent ABS data.
According to ABS data, just 2.61 million Aussies – or about 10 per cent of the population – earn $100,000 or more a year. Many people will never reach a six-figure income in their working lives.
