I want to know the answer to the following question:
As of 2011 what was the population of the core of London?
All the background I'm provided with is that "London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England.". Is that enough to answer the question?
Answer: yes
