Grounding Health Reports

Use `get_weekly_deaths` to pull current death data. By indexing this output into a vector store, you create a searchable knowledge base of historical mortality trends. Later, if a user asks about regional health changes, LlamaIndex retrieves the specific weekly death records and combines that factual API data with surrounding documents for a grounded answer.

Cross-Referencing Demographics

Need to check how population projections affect reported well-being? Run `get_population_projections` and index the resulting sex ratios. The RAG application then allows you to query documents about social policy against this specific, indexed demographic data. This lets developers build complex applications that answer questions like: 'What policies were proposed when older people ratios increased in X area?'

Analyzing Localized Crises

Run `get_suicides` to get local authority suicide counts. Index this data alongside the `get_wellbeing_local` results. This combined index makes it easy for LlamaIndex to answer complex queries, such as identifying regions where both well-being scores and suicide rates are trending downward.
