Housing in London 2012

One of my main tasks each year at the Greater London Authority is to publish ‘Housing in London’, the evidence base document for the Mayor’s London Housing Strategy. It summarises key facts and trends across a range of housing-related topics, with an emphasis on visuals. The 2012 edition was published online just before Christmas and is available here (warning, it’s an 11mb PDF).

I plan to publish a few of the charts from Housing in London 2012 on this blog. Below is the very first chart in the document, taking a 110-year view of trends in population, households and average household size in London based on Census data.

London’s population grew rapidly in the last decade, reaching 8.2m in 2011 and fast approaching its previous peak recorded in the 1939 Census. The number of households also grew but not so quickly, with the result that average household size increased for the first time in at least a century. This is likely due in part to housing supply not keeping up with demand.
