Just under 50% of women are waiting until they reach 30 to give birth, according to the latest figures from the Office for National Statistics.
In 2010, 48% of all infants born were to mothers aged 30 and over, up from 47% in 2009 and 46% in 2000.
The last time so many babies were born to women of this age was after the Second World War, in 1946.
The proportion of mothers under the age of 25 has fallen steadily since its peak in the early Seventies.
There are warning signs for the police and Home Office, with the increase in theft. And earlier this week the British Retail Consortium's Survey showed an increase of over 15% in the cost of retail crime alongside a drop in the proportion of crime reported by retailers to the police from 48% to 16%.
This is perhaps why the Office for National Statistics has begun to express concern that apparent reductions in police recorded crime may be exaggerated.
Crimes recorded in virtually all categories have fallen in the year ending September 2012 compared with the previous year with significant reductions in vandalism, burglary and vehicle thefts.
Pickpocketing was one of the few sub-categories that saw an increase, which may be due to the popularity of hand-held devices like iPhones, mp3 players and tablets.
- Violence against the person - down 5%
- Homicide - down 10%
- Attempted murder - down 2%
- Burglary - down 8%
- Anti-social behaviour incidents - down 2.4%
- Pickpocketing - up 6%

The crime prevention minister Jeremy Browne has welcomed the latest figures from the Office for National Statistics, saying:
Police reform is working. We have swept away central targets, reduced bureaucracy and these figures show forces are rising to the challenge of doing more with less. Many have achieved significant reductions in crime with reduced budgets.
Police records "overstate the true rate in which crime has been falling" according to the latest analysis from the Office for National Statistics.
The number of crimes recorded by police and those reported by residents in England and Wales both show the number of crimes is falling, but at different rates.
Police records suggest that crime rates dropped by 41% since 2002/03, compared to a 26% fall in the records of the Crime Survey for England and Wales.
In the last five years, the number of police-recorded crimes fell by 960,000, while the crime survey showed a fall of just 560,000.
Just over half (53%) of all babies registered in 2011 were born to parents who were married or in a civil partnership, according to figures from the ONS.
The figure is a substantial drop from 1986 when the proportion was closer to 80%.
However, the number of births registered by sole parents (almost 6%) has fallen since 2001 while more parents are co-habiting (31%).
The average age of mothers in England and Wales in 2011 was 29.7 years, according to the most recent figures from the Office for National Statistics. The average age of first-time mothers was 27.9.
Nearly half of all births in 2011 (49%) were to mothers over the age of 30, according to the latest figures from the Office for National Statistics.
For fathers, nearly two-thirds (65%) were over the age of 30.
Overall crime in England and Wales has fallen by 8% to 8.9 million in the year to September 2012 compared with the previous year, according to the latest figures from the Office for National Statistics.
Crimes in all categories were lower for the year, with notable decreases in vandalism, burglary and vehicle-related theft.
This was the lowest level since the Crime Survey for England and Wales (CSEW) began in 1981.
The standard of living in the UK was the sixth best in Europe last year, with the country now also trailing Germany and Austria.
The UK was already behind Luxembourg, Norway and Switzerland, but fell two places in the 2011 list after higher prices hit households - judged by Bank of England governor Sir Mervyn King last year to be the harshest squeeze since the 1930s.
The drop came as prices in the UK rose to 3% above the EU average in 2011.
The measure by the Office for National Statistics and Eurostat takes in all goods and services that a household consumes and includes benefits in kind like health and education.
