We recently learnt about a borough scoring system on the GLA's website which you may be interested in looking at. Click hereto see it. You do not need to log in.
Once there, wait for the data to load. The scores are based on statistics for health, crime rate, GCSE results, access to public transport, open spaces etc. You can change the weightings of these statistics depending on what is important to you. The latest year is 2013.
