Definitions and limitations

Travel time is MODELLED: the cost of crossing each 1 km cell on the friction surface, summed along the least-cost path to the nearest mapped health facility. The facility set behind the surfaces is OpenStreetMap and Google Maps hospitals and clinics, public and private together, with no information on staffing, opening hours or quality — so this measures geographic access to a mapped point, not to a working service. Motorised assumes a vehicle is available; walking-only assumes none. Population weights are WorldPop 2020, which puts Gilgit-Baltistan at about 1.1 million against 1.7 million in the 2023 census, so the north's headcounts are understated. Thresholds are strictly greater than 30, 60 or 120 minutes. mot_/wal_ = motorised / walking-only surface; *_mean is the unweighted mean of valid cells, *_popw_mean the population-weighted mean; *_pct_pop_gtN the share of people more than N minutes away. Manora Cantonment has no valid cells: its blanks are missing estimates, not zero. The tehsil grid holds 1,175,119 cells and 219.6 million people, 4,671 cells fewer than the district build because the two boundary files rasterise differently, so tehsil rows do not recombine exactly to health_access_district (22.10 v 22.13 minutes nationally). The seven ex-FATA merged districts are Khyber Pakhtunkhwa and carry merged_district = 1. This is the table the map's Health → Travel Time to Care (tehsil) layer draws.
