Description: This dataset represents a district‑level infrastructure vulnerability assessment for KwaZulu‑Natal, developed by aggregating local‑municipality infrastructure vulnerability indicators to existing district municipality boundaries. The analysis is intended to support disaster risk profiling, comparative vulnerability assessment, and strategic planning at district scale.Infrastructure vulnerability was first assessed at local municipality level using household service delivery and infrastructure access indicators that reflect exposure to service failure, health risks, and reduced adaptive capacity. These indicators were compiled in the LocalMunicipalities_InfrastructureVulnerability dataset and include measures of sanitation type, cooking fuel source, and refuse disposal practices.For district‑level aggregation, centroid point features were generated from the LocalMunicipalities_InfrastructureVulnerability polygons, with each centroid retaining the associated municipal‑level infrastructure vulnerability attributes. These centroid points were spatially joined to pre‑existing district municipality polygons using a spatial containment relationship.A one‑to‑one spatial join was applied, and municipal‑level infrastructure vulnerability values were summed for each district. The resulting field represents the aggregated infrastructure vulnerability score for each district municipality and reflects the combined contribution of local municipalities within that district.Infrastructure vulnerability values are relative and comparative, not absolute measures of infrastructure condition or service adequacy. Districts with higher aggregated values are interpreted as exhibiting greater concentrations of infrastructure‑related vulnerability, particularly in relation to sanitation, energy access, and waste management deficiencies. This dataset is intended to be interpreted alongside district‑level social and economic vulnerability layers as part of an integrated, multi‑dimensional vulnerability assessment.This is a screening‑level analytical product and does not represent real‑time service delivery conditions or engineering‑level infrastructure assessments.
