Statistical agencies are government organizations responsible for collecting, analyzing, and disseminating statistical data. They provide essential information on various aspects of society, such as population demographics, economic performance, and social trends. This data helps policymakers, researchers, and the public make informed decisions. These agencies often conduct surveys and censuses, like the U.S. Census Bureau in the United States or Eurostat in the European Union. Their work ensures transparency and accountability in government, as well as supports research and planning in both public and private sectors.
