The number of US homes without landlines increased to 18 percent in 2008. Most of these homes include adults living with unrelated roommates, renters and young people. An additional 13 percent of homes receive most of their calls via cell phone but have a connected landline. The reasons for this trend is a cheaper phone plan and 24/7 availability.
Many people still feel that landlines provide security that wireless phones cannot. In an emergency, 911 dispatchers can only locate your exact home address through your landline, whereas cell phones only provide a longitude-latitude location, which is accurate only within 50-300 meters. In event of a power outage, non-cordless phones can be used to contact emergency services.
