The 1990 United States Census was the 22nd national census conducted in the U.S. It collected demographic information about the population, including age, sex, race, and housing characteristics. The census recorded a total population of approximately 248.7 million people, marking a 9.8% increase from the previous census in 1980. This census was notable for its use of new technology, including computer-assisted telephone interviewing. It also introduced the concept of the long form and short form questionnaires, allowing for more detailed data collection. The results provided essential information for government planning and resource allocation.
