The UK population grew by 408,000 in 2008 - the biggest increase for almost 50 years, according to the Office for National Statistics.
The total number of people passed 61m for the first time, with changes in birth and death rates now a bigger cause of growth than immigration.
The numbers of people arriving minus those leaving actually fell by 44%.

What is the 2030 Perfect Storm idea?
As the world's population grows, competition for food, water and energy will increase. Food prices will rise, more people will go hungry, and migrants will flee the worst-affected regions.
PERFECT STORM 2030 On Monday BBC correspondents report on the problems identified by UK chief scientist John Beddington, in his forecast of a "perfect storm" of food, water and energy shortages in 2030. On Tuesday they address the implications, and possible solutions.

Shanghai urges 'two-child policy'
China's only children are often spoiled "little emperors"
Officials in Shanghai are urging parents to have a second child, the first time in decades the government has pushed for more babies.
A public information campaign has been launched to highlight exemptions to the country's one-child policy.
Couples who were both only children, which includes most of the city's newly-weds, are allowed a second child.
The move comes as China's most populous city becomes richer and older, with the number of retired residents soaring.
"Shanghai's over-60 population already exceeds three million, or 21.6% of registered residents," said Zhang Meixin, a spokesman for the city's Municipal Population and Family Planning Commission.

If you want to go green, buy Spanish strawberries - Green Living, Environment - The Independent
The belief that local is best when it comes to measuring the environmental impact of our food is often wrong, says new research
Millions of Britons who think they are doing their bit for the environment by choosing home-grown food over produce imported from thousands of miles away could actually be having the reverse effect, according to a startling new report.
The "food miles" philosophy that decrees anything transported over distance is worse for the environment than something closer to home is frequently flawed, according to researchers funded by the Department for Environment, Food and Rural Affairs (Defra).

Glaciers around the world are retreating at unprecedented rates as temperatures rise due to climate change. Some ice caps, glaciers, sea ice and even an ice shelf have disappeared altogether in this century and many more are retreating so rapidly that they may vanish within a matter of decades

Barcelona gets new water supply
A desalination plant has opened near Barcelona - said to be the biggest of its type in Europe - to ease chronic water shortages.
A drought last year forced Barcelona to import drinking water by tanker. It was one of Spain's driest years on record.
The new plant at El Prat del Llobregat will provide 24% of the water consumed in the Barcelona area, officials say. It went into operation on Monday.
Two more desalination plants are being built in the Catalonia region.
The new plant near Barcelona will provide 200m litres (44m gallons) of drinking water daily for the city's 4.5 million people.
If the UK were a village of 100 people... - Features, Health & Families - The Independent
There are, according to the estimate for this month, 6,790,062,216 people in the world. It's hard enough to say the number, never mind picture those people. You could round it up to a less tongue-twisting 6.8 billion, but does that make such a frightening figure any easier to compute? When you try, do you see faces, or just more brain-frying strings of digits?
The sheer vastness of the data we gather in our attempts to understand the world around us has been challenging statisticians since the earliest censuses. The "size of Wales" approach to number-crunching is popular among headline writers; but is it helpful, for example, to imagine the global population in terms of 75,445 Wembleys, or, indeed, 2,341 Waleses? The numbers are still too big.
It's the same with the news we read and hear each day. What does it mean when we're told that unemployment has risen by 281,000? Is that a huge number? Or just a big one? The stories are about people, but it is often hard to see beyond the figures.

Top Ten Technologies for an Alternative Energy Future « EE/RE Investing
The muscle car of energy efficiency. Combined heat and power isn’t sexy… it’s just using the “waste” heat from your powerplant for some useful purpose. Like cooking your lunch on you car radiator, but using every bit of waste heat you can… Combined heat and power can use 90% of the power in your fuel source for useful work. And now you can have it in your home.
They’re tall, they’re low-tech, and they’re baseload power. They don’t pollute, and the fuel is free. What’s not to like?
8. Molten salt thermal storage
It’s cheaper to store heat than electricity, and molten salts can store a ton of BTu’s very cheaply. And concentrating solar power can produce a ton of heat… without pollution or fuel.
7. Light Emitting Diodes (LEDs)
More lumens per watt… now that’s energy efficiency.
Our energy efficient cars can make the electric grid work better.
5 & 4. Cellulosic Ethanol and Biodiesel from Algae
The two technologies that have real hope of replacing gasoline and diesel as liquid fuel for our cars… We’ll still need massive efficiency gains and Plug-in-Hybrids to reduce our total fuel use, but even with those, corn ethanol and biodiesel from traditional oil crops just can’t produce enough volume.
3. Time of Use pricing and Demand Side Management.
Sometimes the best ideas are the simplest. To make the best use of wind power, we can store power until it is needed, or we can give people incentives to use it when it is available.
Time of use pricing is also a great boon for solar, because solar energy tends to be available near times of peak demand.
Finally, time of use pricing shaves peak demand, which means that we can delay building new fossil fired generation, while renewables get cheaper by the year.
2. Terra Preta
Discovered by aboriginals in Brazil, thousands of years before Columbus, mixing carbon into unproductive soils can make them much more productive… and the carbon stays there for thousands of years. Using charcoal dust as a fertilizer not only holds the hope of a replacement for fertilizer based on fossil fuels, but it is also an easy way to sequester carbon.
1. Compact Fluorescent Lightbulbs
Where else can you get a 1000% payback with little or no risk?

Coastal path will open up 1,000 miles of previously inaccessible land - Telegraph
Land that will be opened up includes the cliff tops south of Berwick-upon-Tweed in the Borders, the crumbling Norfolk coast south of Sheringham, inaccessible land along the Solent and urban areas around Liverpool. The path will also make it possible for ramblers to walk through golf courses, country estates and farms that are currently closed to the public.

Huge Earthquake Strikes Single Building in 'Shake Test' - Science News | Science & Technology | Technology News - FOXNews.com
At midnight in Japan on Tuesday, July 14, one of the worst earthquakes in human history took place in Miki City.
But the massive quake — which measured a 7.5 on the Richter scale — only struck one building, a seven-story wooden structure exposed to a simulated earthquake inside a Japanese laboratory. Happily for the U.S. engineers who designed the building, it did not fall down.
The full-scale building sat on a metal shake table that rocked it violently back and forth.
The table, designed to hold up to 2.5 million pounds, reproduced forces based on those recorded at a 1994 earthquake at Northridge, Calif., but scaled up by 180 percent to simulate an earthquake so violent it would only occur on average once every 2,500 years.
