At the end of July 2018, the Greater London Authority released the 2018 edition of its annual Housing in London report.

This report is the most extensive source of data on housing in the capital, serving as the evidence base for the Mayor’s London Housing Strategy. It is a resource for policymakers, practitioners and academics alike.

Key statistical tables for every London borough are provided at the beginning of the document, and the report has six thematic chapters:
1. Historical background
2. Demographic, economic and social context
3. Housing supply and empty homes
4. Housing costs and affordability
5. Housing need
6. Mobility and decent homes

The raw data included in the report is also provided as an Excel download, to assist analysts wanting to undertake their own analyses.

From the 99 charts and maps in the report we have picked out two examples.

The first compares the annualised rate of population and housing stock in the last five years in London and a set of other cities around the world. It shows that while population growth has outpaced growth in the housing stock in London, in a number of other cities (mostly in East Asia) the reverse is true.

The second chart shows the growing importance of the Help to Buy equity loan in the housing markets of many London boroughs, by charting the number of sales funded through Help to Buy as a proportion of the total new build private completions in each borough between 2013/14 and 2016/17.

Full details of data sources for these and the other charts are provided in the report itself.
