2023 Healthy Streets Scorecard results

There has been little progress in Sutton to make streets healthier. Sutton has 16% CPZ coverage final score (well below outer London borough Ealing on 47%), 14% LTN coverage (well below outer London borough Waltham Forest on 48%), under 5% bus priority, 26% of borough-controlled roads with 20mph speed limits, whereas 17 of boroughs have over 80% and 12 have them borough-wide. Car ownership rates are among the highest in London with 101 cars per 100 households, this compared to leading outer London borough Greenwich with 65 cars registered per 100 households. With the council declaring a climate and ecological emergency three years ago, we would like to see concerted effort from the council in all the borough’s low-scoring metrics.

The Healthy Streets Scorecard combine scores for ten indicators to create an overall Healthy Streets score for each borough. See the graph below for 2023 results (includes 2019 – 2022 results for comparison). For more detail visit the London-wide overview of the 2023 results. You can also:

Scorecard (factored score) chart explained

In the chart above, each borough has been given a factored score. Factor scores are composite variables which provide information about a borough’s placement on a scale. Factor scores are given by F=XB, where X is the indicator normalised score for a borough and B is the factor score coefficient (or weight). Each indicator is weighted as 1, or 0.5 if there are two parts to one indicator, for example Modeshare has a weighting of 1, Active travel – walking has a weighting of 0.5 and Active travel – cycling has a weighting of 0.5. The borough’s total factored score is the sum of all indicator factored scores which is then factored to 10 (multiplied by the number of indicators/10) to give a value on the scale between zero and 10. We can then compare boroughs against each other on the scale.
