Metric catalogue

Current metric keys, units, geographies, projection, nation scope and sources.

This reference lists the 114 metrics in the current full-access catalogue. GET /v1/metrics is the discovery contract for the caller’s own organisation; its result can be smaller because access is checked per metric.

A postcode request accepts Catchment and Authority keys together. A cell request accepts only Cell keys. The direct authority endpoint accepts only Authority keys.

“Projected” means the metric depends on supported population projection inputs. With a valid projection_year, supported inputs are projected and dependent metrics are recalculated. Missing required projection inputs can make a value unavailable; optional multipliers can leave some source counts unchanged. Authority figures and current supply are not projected.

Nation scope follows the catalogue metadata and is not a guarantee that every location has data. A missing value is null. Source data can describe different periods; use period_basis from the catalogue and per-value details from the response.

Care metric definitions

Keys	Definition
carehome_demand	Estimated care-home demand from older age-band populations, not a measured waiting list. The omitted-year default uses source population.
existing_beds_all, existing_beds_ensuite, existing_beds_wetroom	Published beds in open non-specialist homes in the catchment.
undersupply_existing_all, undersupply_existing_ensuite, undersupply_existing_wetroom	Demand minus the matching existing supply. Negative is surplus. The categories overlap, are not additive, and exclude pipeline beds.
planned_permitted_beds, planned_undecided_beds	Separate care-bed totals in the published permitted and undecided planning pipeline.
planned_permitted_count, planned_undecided_count	Counts of projects in those pipeline categories.
avg_fee_residential_week, avg_fee_nursing_week	Unweighted means of usable weekly private-pay quoted fees, separate by care type.
bed_weighted_avg_fee_residential_week, bed_weighted_avg_fee_nursing_week	Means weighted by each contributing home’s total beds.
median_fee_residential_week, median_fee_nursing_week	Medians of usable weekly private-pay quoted fees, separate by care type.
fee_residential_count, fee_nursing_count	Homes contributing usable fee data.
fee_residential_beds_covered, fee_nursing_beds_covered	Total beds at the homes contributing fee data.

Residential fee statistics require at least five homes and 150 covered beds. Nursing fee statistics require at least three homes and 100 covered beds. Below-threshold fees are unavailable, while the sample counts remain reportable. Five years of historical private fees is not available.

​

Authority metric definitions

Keys	Definition
la_avg_fee_residential_week, la_avg_fee_nursing_week	Latest usable authority fee by financial year and care type. Each value has its own period, reporting authority and source metadata where available.
la_occupancy_pct	Combined general/dementia residential and nursing occupancy, excluding specialist/other beds.
la_residential_occupancy_pct, la_nursing_occupancy_pct	Separate older-adult occupancy categories. Each uses the latest published month for its category and requires that authority’s reading for that month.

These figures describe the reporting authority, not a radius or individual home. Missing English occupancy and non-English occupancy remain unavailable; no comparison-area value is substituted.
