London's Population: Barnet's Brent Cross to take the strain? (Assuming a naïve new punter can be found, to replace the discredited Hammerson)

"Three variants of trend-based population projections and corresponding household projections are currently available [from the Greater London Authority]. These are labelled as High, Central and Low, and differ in their domestic migration assumptions beyond 2017.

"The economic crisis has been linked to a fall in migration from London to the rest of the UK and a rise in flows from the UK to London. The variants reflect a range of scenarios relating to possible return to pre-crisis trends in migration.

• High: In this scenario, the changes to domestic migration flows are considered to be structural and recent patterns persist regardless of an improving economic outlook.


• Low: Changes to domestic migration patterns are assumed to be transient and return to pre-crisis trends beyond 2018. Domestic outflow propensities increase by 10% and inflows decrease by 6% as compared to the High variant.


• Central: Assumes recent migration patterns are partially transient and partially structural. Beyond 2018, domestic outlow propensities increase by 5% and inflows by 3% as compared to the High variant."

"The Mayor of London has commissioned work to develop a Long Term Infrastructure Investment Plan for London, working with other members of the GLA Group, London Councils and drawing in external expertise where appropriate.

"The Mayor’s 2020 Vision sets out the critical infrastructure required on the road to 2020 and beyond. The London Plan, which is currently undergoing further alterations, sets out London’s needs to 2036. Given the long-term nature of infrastructure planning, the next set of investments needs to be drawn up if London is to sustain and accommodate its growth for the rest of t he first half of this century.

"The Long Term Infrastructure Investment Plan will set out London’s strategic infrastructure requirements to 2050 across the main aspects of infrastructure, namely public transport, roads, energy, water, waste, ICT and partially social infrastructure. Uniquely, it will also provide a bottom up assessment of London’s infrastructure requirements and the funding and financing options to pay for them.

"It will ensure the infrastructure London needs for continued economic growth is clearly articulated. Our aim is to demonstrate to the Government, Londoners and investors that infrastructure is a key priority and that London has a clear plan to ensure it has the necessary infrastructure to meet the demands of its growing population and remain a leading world city.

"This paper sets out the progress to date in developing the first Long Term Infrastructure Investment Plan for London. It discusses the key the mes that are emerging across infrastructure types that in our view need to be addressed if London is to effectively plan for and deliver its long term infrastructure requirements. It outlines the steps we will undertake to publish a Long Term Infrastructure Investment Plan for London by the Autumn 2014."
