Census Bureau News, citing latest data, said Thursday the percentage of U.S. households with cellphones increased from 36 percent in 1998 to 71 percent in 2005.
During that same time period, ownership of traditional telephone landlines in U.S. households decreased from 96 percent to 91 percent overall.
Age played an integral role in cellphone and landline usage.
While 35 percent of households 29 or younger used cellphones in 1998, that figure jumped to 81 percent in 2005. Landline usage by that same age group went from 93 percent in 1998 to 71 percent in 2005.
In comparison, 98 percent of households of people at least 65 years of age had a landline telephone as of 2005.
Census Bureau News said the percentages were based on the results of the Survey of Income and Program Participation that took place February 2005 to May 2005.
