A new learning activity from Creative Computing .... Surveys, The Census, and Privacy by David H.Ahl Every 10 years, the United States government takes a census of every person in the country. This serves a number of very useful purposes. First, it tells how many people there are in the country. Second, it gives data on living and income patterns and answers questions on whether the quality of life is improving, indicates the decline (or growth) of disadvantaged sectors of the population, and on economic growth. Also it gives valuable information on educational attainment. It also yields vital statistics on population mobility, mortality, birth rates, etc. Private industry, various government bodies, colleges, and other groups also take surveys from time to time. Here are some examples of recent surveys: The Department of Transportation surveyed passengers on the NY-Washington Metroliner about passenger rail services. Educational Systems Research Institute surveyed the graduates of career education programs in 15 cities for the U. S. Office of Education. Ohio State University surveyed its students on a number of issues including the reaction to their black studies program. General Mills Corporation surveyed consumers about their preferences for various snack and cereal products. Consumer Mail Panels (for several insurance companies) surveyed a cross section of people involved in auto accidents to see how well their insurance claims were handled.
