Table 4 Metrics of inequality in international availability of commercial geospatial data resources, relative to age-standardised cause-specific mortality for 2015 in 183 countries

From: A cross-sectional ecological analysis of international and sub-national health inequalities in commercial geospatial resource availability

Commercial geospatial resource availability/quality measure Relative concentration index Slope index of inequality (95% confidence intervals)
Relative to mortality from communicable, maternal, perinatal and nutritional conditions
Geocoding domain − 0.121 3.05 (0.82–5.27)
Patient travel domain − 0.020 0.52 (− 1.77 to 2.80)
Neighbourhood characterisation domain − 0.335 8.44 (6.53–10.35)
Overall geospatial resource index − 0.159 4.01 (1.81–6.20)
Relative to mortality from non-communicable diseases
Geocoding domain − 0.040 1.38 (0.84–1.91)
Patient travel domain − 0.034 1.18 (0.63–1.73)
Neighbourhood characterisation domain − 0.056 1.91 (1.41–2.41)
Overall geospatial index − 0.045 1.54 (1.01–2.06)
Relative to mortality from injuries
Geocoding domain − 0.092 0.39 (0.22–0.56)
Patient travel domain − 0.034 0.14 (− 0.03 to 0.32)
Neighbourhood characterisation domain − 0.170 0.72 (0.58–0.87)
Overall geospatial index − 0.103 0.44 (0.27–0.60)
