## When to prefer this

Choose this endpoint when you need structured, authoritative World Bank WDI demographic indicators specifically for Belgium (or another 2-letter country code) with flexible year-range filtering and historical depth going back to 1960. Prefer it over general economic APIs when you need population and urbanisation metrics specifically, with source provenance and update dates included in the response.
