Every pound spent on development for the London 2012 Olympics is worth 75 pence in long term investment for east London.
According to the Department for Culture Media and Sport the area has benefited from a new park, world class sports venues, homes and first class transport links.
The figures are contained in an interesting article in the FT today - the first of a three-day special counting down to the special "one year to go" events of Wednesday.
While pointing out the many positives for the area, in essence the article is about ministers playing down the economic benefit of the Olympics.
"You don't really know the benefits until five years after the event" is the conclusion of Michael Ridge, head of public policy at the Frontier Economics consultancy.
It was interesting to see then against this backdrop that house prices around the Olympic Park have risen by 11.9% since London was awarded the Games in July 2005.
Figures from Zoopla.co.uk said the rise in prices in east London outstrips the UK average of 7.2% growth over the same period.
In total, £30.8bn has been added to the value of residential properties located in close proximity to Olympic sites in the UK since the announcement, with £6.4bn in added-value to house prices in east London alone.
That sounds like economic benefit to me...
