The results of a national census are too often viewed as of little use except for allocating seats in the House of Representatives of the U.S. Congress. This essay argues that a broader view of census data should be taken; the data can prove valuable for instructional use across the secondary school curriculum. An overview of population education is provided, as well as examples of ways in which secondary schools are incorporating demographics into their instructional programs. A list of agencies and organizations that produce information and materials for population education is included. (DB)
