This counts designations rather than area or population, so a small central borough with a dense historic core reads far above a large outer one — which is the point: the constraint on what can be built falls very unevenly. An earlier version used the listed-building-outline dataset and reported zero for Sutton; that dataset is polygons contributed by individual councils and measures which of them have done the mapping.","category":"housing","categoryLabel":"Housing","cadence":"monthly","placeholder":false,"landingPage":"https://londongraph.com/g/where-protection-concentrates","markdown":"https://londongraph.com/g/where-protection-concentrates/index.html.md","source":{"name":"MHCLG","url":"https://www.planning.data.gov.uk/","licence":"Open Government Licence v3.0","licenceUrl":"https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/"},"updatedAt":"2026-07-31T23:58:58.676Z","release":{"label":null,"publishedAt":null,"resourceUrl":null,"methodologyUrl":null,"sha256":null},"observations":[{"series":"","buckets":["Westminster","Camden","Kensington and Chelsea","Islington","Lambeth","Southwark","Tower Hamlets","Richmond upon Thames","Barnet","City of London","Hackney","Greenwich","Hounslow","Hillingdon","Bromley","Lewisham","Wandsworth","Ealing","Enfield","Harrow","Haringey","Hammersmith and Fulham","Merton","Sutton","Croydon","Kingston upon Thames","Havering","Redbridge","Newham","Waltham Forest","Bexley","Brent","Barking and Dagenham"],"values":[4014,1968,1349,1049,953,919,916,817,651,637,555,540,518,438,412,367,312,308,301,295,288,268,243,209,179,163,146,134,125,118,114,94,48],"unit":"listed buildings","metadata":[{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{}]}],"areaStatistics":null,"visualizations":[{"id":"overview","label":"Overview","description":"Westminster has eighty times as many listed buildings as Barking and Dagenham.","url":"https://londongraph.com/g/where-protection-concentrates","renderer":"primary","default":true,"timeControl":"inherit","datasets":[],"transform":null,"controls":null,"metrics":[],"caveat":null},{"id":"distribution","label":"Distribution","description":"Show every published value around the median and quartiles.","url":"https://londongraph.com/g/where-protection-concentrates?view=distribution","renderer":"distribution","default":false,"timeControl":"inherit","datasets":[],"transform":null,"controls":null,"metrics":[],"caveat":null}],"availability":"observations","note":"The release is complete for the measures represented on the graph page."}
