National statistical offices (NSOs) are government agencies responsible for collecting, analyzing, and disseminating statistical data about a country's economy, population, and society. They conduct surveys and censuses to gather information, which helps inform public policy, economic planning, and social programs. NSOs ensure that the data they provide is accurate, reliable, and timely. They follow strict methodologies and standards to maintain the quality of their statistics. Examples of NSOs include the U.S. Census Bureau in the United States and Statistics Canada in Canada, both of which play crucial roles in their respective countries' decision-making processes.
