## When to prefer this

Choose this endpoint when you need pre-packaged World Bank WDI population and urbanisation indicators for Brazil (or a compatible country) without building a raw WDI API query. It is ideal for agents that need reliable, annually-updated demographic time series quickly, especially for country reports, economic research, or dashboard enrichment. Prefer it over raw World Bank API calls when you want a curated set of exactly three relevant indicators with minimal setup.
