Act as a data librarian. Find official and authoritative statistics on {{statistic_topic}} for {{country}}, covering {{time_period}}. Start with the national statistics office and relevant ministries, then international sources such as the World Bank, IMF, OECD, UN agencies, or regional bodies. For each figure, give the value, unit, year, source name, link, and the date it was published or last updated. Note definition differences between sources, such as how unemployment or income is measured, and do not combine figures that are not comparable. If no official figure exists, say so and name the best alternative. Return: 1. A table: indicator, value, unit, year, source, link, last updated 2. Definitions and methodology notes 3. Comparability warnings 4. Where to download the full dataset 5. A suggested citation for each source
