Over 35% of American households have given up on landlines totally
You can figure that this trend will only continue because 40% of those 18 or younger have replaced the landline with a cellular connection. That figure is 34% for adults. When the youngsters get older, do you think they are going to add a landline? As today's 18 and unders become tomorrow's adults, the percentage of adults relying on cellular will only rise. Years ago, the cost of owning a cell phone and subscribing to a calling plan would have made talk of relying on wireless sound crazy. But in this era when 6 year olds are sporting the Apple iPhone, owning a landline is like holding on to your appendix. Maybe that explains why the CDC was involved in the survey!
