Human Health Statistics (Gezondheid) -- CBS / Netherlands

What This Dataset Is

INSPIRE-harmonized health statistics for the Netherlands from CBS (Centraal Bureau voor de Statistiek / Statistics Netherlands). Contains two indicators at the NUTS2 (province) level:

1. Doctors per 100,000 inhabitants (2017 data)
2. Deaths per 100,000 inhabitants (2016 data)

This is a very small dataset: 12 provinces x 2 indicators = ~24 features total. Each feature is a provincial boundary polygon with the associated health statistic. It is the Dutch contribution to the European INSPIRE Human Health and Safety theme.

How to Access

Two GeoParquet files (one per indicator) and a combined PMTiles file for web visualization are available from Source Cooperative. Native CRS is EPSG:3035 (ETRS89-LAEA) — coordinates are in meters.

Feature Types

Each layer has 12 features (one per province).

Schema -- Field Meanings

Additional INSPIRE-standard metadata fields may be present depending on the WFS response.

Important Columns

The columns you'll most often use:

• identifier -- NUTS2 province code (the join key for Eurostat/INSPIRE data)
• text -- province name in Dutch
• geometry -- provincial boundary polygon

NUTS2 Province Codes

Geometry Notes

• CRS is EPSG:3035 (ETRS89-LAEA / European Lambert Azimuthal Equal-Area). This is the pan-European standard grid CRS used by INSPIRE, NOT the Dutch national CRS (EPSG:28992). Coordinates are in metres on a European-wide grid.
• To convert to WGS84 (lon/lat) for web mapping:

• Bounding box in WGS84: [3.37, 50.73, 7.24, 53.55] (all of Netherlands)

INSPIRE Context

This dataset is part of the INSPIRE (Infrastructure for Spatial Information in Europe) Directive. INSPIRE harmonizes spatial data across EU member states to enable cross-border interoperability. The Human Health theme (Annex III) provides health-related statistics referenced to standard European administrative units (NUTS).

Key implications:

• NUTS2 level only -- provincial aggregation, no finer resolution
• EPSG:3035 -- the mandated INSPIRE CRS for pan-European analysis
• INSPIRE-standard field names -- localId, namespace, identifier follow the INSPIRE Generic Conceptual Model
• Designed for European comparison -- values are rates per 100,000 for cross-country comparability

Caveats

• Data vintage: Doctor counts are from 2017, death rates from 2016. This is a snapshot, not a time series. The data is not regularly updated.
• Provincial level only: NUTS2 aggregation means only 12 spatial units per indicator. No municipality-level or neighborhood-level breakdown.
• EPSG:3035 coordinates: Unlike most Dutch datasets (which use EPSG:28992 RD New), this uses the European INSPIRE CRS. You must transform coordinates when combining with other Dutch datasets.
• INSPIRE overhead: Field names follow INSPIRE conventions, which can be verbose. The namespace and localId fields are INSPIRE administrative metadata, not analytical data.
• Tiny dataset: Each parquet file is under 200 KB — small enough to load entirely into memory without spatial filtering.

Visualization Styles

One Mapbox GL v8 style is available for interactive map visualization via the PMTiles file.

Style files are Mapbox GL v8 JSON with relative PMTiles source paths. They can be used with MapLibre GL JS, OpenLayers (via ol-mapbox-style), or any Mapbox GL v8-compatible renderer.

• styles/default.json — Health indicator choropleth. Red sequential ramp showing doctors-per-province statistics. Light pink (fewer) to deep red (more). Province-level view of healthcare distribution.
