Papua New Guinea Healthcare and Education Accessibility Indicators with Population Data

A 2026-04-11 updated dataset from HeiGIT (Heidelberg Institute for Geoinformation Technology) providing spatial accessibility metrics for healthcare and education services across Papua New Guinea. It calculates populations within travel-time isochrones (10-120 minutes for hospitals, 5-50 km for schools) using OpenStreetMap and 100m-resolution WorldPop data. Results are aggregated at national and finer administrative levels (ADM 1–4).

Use Cases

• Modeling healthcare service catchment areas based on travel-time isochrones and population data.
• Assessing school accessibility for school-age populations using distance-based catchment zones.
• Comparing service coverage across different administrative levels (ADM 1–4) within Papua New Guinea.
• Analyzing incremental population gains within specific distance or time intervals from service points.

Strengths

• Integrates multiple open data sources: OpenStreetMap for routing, WorldPop for 100m-resolution population estimates.
• Provides metrics for two critical service categories: education and healthcare (including primary_healthcare).
• Calculates both cumulative and interval-based population shares for detailed accessibility analysis.
• Results are summarized at multiple administrative levels where data is available.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or source bias inherent to the underlying OpenStreetMap and WorldPop data.
