2022 Heat Vulnerability Index for Greater Sydney at SA1 Scale

A 2022 composite index for Greater Sydney combines urban heat, built form, and demographic data aggregated to Statistical Area Level 1 (SA1). The dataset, produced by the NSW Department of Planning, Housing and Infrastructure, integrates indicators of heat exposure, sensitivity, and adaptive capacity. Broad comparisons can be made with a 2016 version, though methodological differences limit direct temporal analysis.

Use Cases

• Map spatial distribution of heat-vulnerable populations based on composite vulnerability scores.
• Analyze correlations between urban heat island effects and demographic sensitivity indicators.
• Inform targeted heat mitigation strategies by identifying high-risk SA1 areas.
• Compare relative heat vulnerability patterns between the 2022 and 2016 datasets.

Strengths

• Provides a fine-grained spatial analysis at the SA1 scale for Greater Sydney.
• Integrates multiple data domains: land cover, urban heat, and demographic data.
• Built upon a published methodology established for a 2016 version.
• Available under a permissive CC-BY-4.0 license.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Direct comparability with the 2016 dataset is limited due to changes in underlying data and study area.
