London is not a cheap place to live. If you want to live at swanky address in a prime location like Knightsbridge or South Kensington, you can expect to spend £33k+ ($48k) in rent. Junior bankers may be well paid, but they're not that well paid. Unsurprisingly, therefore, junior bankers are far more likely to live in the cheaper areas of London like the South East and the East than those at the top of the hierarchy.
New figures from London-based recruitment firm Circle Square show how you're likely to migrate around London as your finance career progresses. Basically, the more senior you are the less likely you are to live in the South East or the East of London and the more likely you are to live in London's North or South West - or not to live in London at all.
