Small-area poverty estimation
Survey data are combined with census and satellite covariates to estimate poverty for districts and neighbourhoods, with uncertainty mapped beside estimates.
GCRI · 社会与人类发展
Spatial statistics estimate social conditions for small areas and map how vulnerability and hazards overlap. In this field they produce poverty and vulnerability maps for places surveys barely cover, always with uncertainty shown.
Spatial statistics and geostatistics analyse data that vary across space, accounting for spatial dependence. They estimate values at unsampled locations and test for spatial patterns. In society and human development and information and public trust, spatial statistics produce continuous hazard and exposure surfaces with uncertainty. They reveal geographic clustering of risks and vulnerabilities across sectors. The canonical description is on STEM Commons.

Social vulnerability estimates are overlaid with hazard maps to identify places where exposure and limited 应对能力 coincide.
Statistical tests identify clusters of deprivation that are unlikely to arise by chance, guiding targeted programmes.

Predictions are tested using spatial cross-validation that respects dependence. Uncertainty maps are compared with independent observations.
| 核查 | 如何开展 |
|---|---|
| 模型验证 | Small-area estimates are compared with direct estimates where samples are large |
| Uncertainty mapping | Every map is accompanied by uncertainty |
| Privacy protection | Maps are aggregated to avoid identifying households |
Results depend on the scale and zoning of analysis. Sparse or clustered sampling limits prediction in unsampled areas.
Assembled from the Nexus Standards area profile 社会与信息风险标准: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.
