Official statistics are statistics published by government agencies or other public bodies such as international organizations as a public good. They provide quantitative or qualitative information on all major areas of citizens' lives, such as economic and social development, living conditions, health, education, and the environment.
Since 1870, the federal government has collected. statistics on the condition and progress of American. education. In the beginning, data were collected on. very basic items, such as public elementary and sec-. ondary school enrollment, attendance, teachers and. their salaries, high school graduates, and expendi-. tures. Over the years, the level of detail has gradu-. ally increased. Today, the National Center for Edu-. cation Statistics has a staff of approximately 130 who. collect information through nearly 40 surveys and. studies and produce more than 175 publications per. year. Statistics paint a portrait of our Nation. By looking. at changes in the data over timeâlike number of. schools, participation rates, completion rates, and ex-. pendituresâwe see how our Nation has progressed.
