According to recent estimates, approximately 75% of U.S. households put up a Christmas tree during the holiday season. However, the number can vary significantly depending on factors such as geographic location, socioeconomic status, and cultural background. In urban areas, the number of households with Christmas trees tends to be lower than in rural areas due to space constraints and differing cultural traditions. Overall, the practice of putting up a Christmas tree remains a popular and integral part of the holiday season for many Americans.
