SDG Indicator 11.7.1: Urban Public Space Availability for 8,873 Cities, 2023

SDG Indicator 11.7.1: Urban Public Space, Availability and Access, 2023 Release measures the average share of a city's built-up area that is open space for public use. The dataset provides estimates for 8,873 urban centers across 180 countries, produced by ESDIS and released on NASA Earthdata. It was computed using OpenStreetMap public space data, WorldPop population grids, and urban center delineations from the JRC GHS-UCDB.

Use Cases

• Benchmarking city-level progress towards SDG 11 based on the proportion of public space.
• Analyzing spatial equity in access to public space based on population proximity within 400 meters.
• Comparing urban public space availability across 180 countries for global sustainability reports.
• Informing urban design and land-use policy based on quantified public space metrics.

Strengths

• Covers 8,873 urban centers, providing a broad global scope.
• Includes data for 180 countries, enabling international comparison.
• Integrates multiple authoritative sources: OpenStreetMap, WorldPop, and JRC GHS-UCDB.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2022-12-31 00:00:00; freshness should be verified.
