The Stridel Access Index.

A destination-accessibility index — how easily a place reaches everyday destinations on foot — scored per ~175 m cell and shown here aggregated to MSOA across UK local authorities.

Tip — click or zoom into a local authority to see its areas, then hover any area for its access score. Zoom out to return to the UK view.

Not comparable across cities

Scores are normalised within each local authority, so a “70” in one city is not the same as a “70” in another. Read each map on its own — there is no league table.

Equity & deprivation (PSED)

Scores correlate with deprivation (ρ ≈ −0.4 at fine grain). This does not mean deprived areas have higher-quality pedestrian environments, and high scores there must not be read as reduced need for footway, crossing or severance investment — they should prompt scrutiny of actual conditions.

An access index — not a walkability score

It measures access to destinations on foot, calibrated to ONS Census 2021 walk-to-work (a commute proxy; peak-WFH year). It does not yet measure on-street walkability — pavements, crossings, severance. Not a safety indicator. MSOA grain.

More local authorities are being added — new areas appear as they clear validation.
