Show the numbers

Inputs to the safety score
Recorded crimes and anti-social behaviour	0
Months of data	3

Severity-weighted crimes per km² per month	0 per km² per month
Search radius	1.6 km

Recorded street-level crime within the search radius, weighted by offence type (violence and robbery x2, ASB x0.5), per km² per month, placed on a log scale from 1 (scores 100) to 300 (scores 0).

Counts recorded crime by location, not risk to any individual; busy city centres score lower because of footfall.
Locations are anonymised to nearby map points by the police.
