Population of Wales hits 3.06 million according to census data


The population of Wales has grown by 153,000 to 3.06m - up 5% on the 2001 count when it was 2.91m - according to the latest census data.

It is the largest growth over 10 years since 1921. Around 90% of growth was due to people moving to Wales.

The population of England grew 7% and the Europe average was 4%.

Of the regions in England and Wales, Wales is only growing faster than north-east and north-west England. London is the fastest growing area.

Of the local authorities in Wales, Cardiff had both the highest population, at 346,000 people, and the largest growth in population with an increase of 36,000, 11.6%, from 2001.

It was also the most densely populated, with 2,500 people per square kilometre, the equivalent of around 25 people on a rugby pitch.

The city is the 50th fastest growing area in England and Wales. Half of the local authorities in Wales saw growth rates of 5% or more.

The fastest growing parts of England are Tower Hamlets, which has increased by 26% in 10 years, Newham, 23%, and Manchester 19%.

Blaenau Gwent is the only part of Wales to see a decrease in population, falling 0.3%, and one of only 17 areas in England and Wales with a fall.

Around one fifth of the population in Wales is now aged 65 and over.

Conwy had the highest proportion with 25%, while the smallest proportion was in Cardiff, 13%, and the city was the only area to see a decrease in the proportion of older people.

Wales also has a higher proportion of 65-year-olds than nearly all the regions of England.

While the population was growing older, there was also a baby boom happening, with a significant increase in the number of under-five-year-olds across England and Wales.

In Wales there were 11,000 more under-five-year-olds in 2011 than in 2001, an increase of 7%. By comparison, the number of under fives in England increased by 13%, approximately twice as quickly as in Wales.

Wrexham had the largest proportion in this age group with 7%, while the smallest proportion was in Ceredigion with 5%.

Jil Matheson, National Statistician, said: "I would like to thank everyone in Wales for their support. The 2011 Census has been a resounding success and I am proud of the incredible effort that has been put in. It is a rich source of information about the population and its characteristics.

“Across England and Wales around 19 out of 20 people responded and we have excellent statistical methods for ensuring we have a complete estimate of the whole population. These statistics will provide valuable information for planners, policy-makers and the public for years to come."

England and Wales increased by 7% between the last two census surveys, the largest growth in numbers seen in any period since records began, the Office for National Statistics said.

There were 56.1 million people living in England and Wales on the day of Census 2011, an increase of 3.7 million since 2001, when there were 52.4 million people.

Figures also showed that one in six people in England and Wales in 2011 was aged 65 and over.

The survey paints a picture of an ageing population, with 430,000 people in England and Wales aged 90 and over, compared with only 13,000 when the Census was carried out 100 years earlier in 1911.

The median age of the population has increased to 39 in 2011, up from 35 in 2001 and 25 in 1911.

But there was also an increase in the number of under fives, with more than 400,000 more in 2011 compared with 2001.

The ONS results show that every region in England and Wales had a larger population in 2011 than 10 years earlier.

The largest increase in population was in London, which grew by 12%, gaining more than 850,000 inhabitants and taking its total population to more than eight million.
