US CDC: 64 Million in US Now Wireless Only

The US Center for Disease control has been tracking the number of households (and related demographics) that have landlines, mobile phones or a combination of mobile and landlines. As of the first half of this year:

More than one of every five American homes (22.7%) had only wireless telephones (also known as cellular telephones, cell phones, or mobile phones) during the first half of 2009--an increase of 2.5 percentage points since the second half of 2008. In addition, one of every seven American homes (14.7%) had a landline yet received all or almost all calls on wireless telephones.

If almost 23% are mobile only and 14% mostly use their mobile phones -- the landline is like a "spam catcher," as Authour likes to say -- then 37% of US households should be considered mobile-centric, where the mobile device is the only or primary means of phone communication. According to the CDC here is the demographic breakdown:

  • 18-24 years: 37.6%
  • 25-29 years: 45.8%
  • 30-34 years: 33.5%
  • 35-44 years: 21.5%
  • 45-64 years: 12.8%
  • 65 years and over: 5.4%

It shows how people under 45 are becoming more and more mobile centric. This has implications for all kinds of things, including of course advertising.

According to the US Census Bureau, there are roughly 113 million US households against 304 million people, or 2.6 people on average per household. Twenty-two percent of these numbers equals about 64 million people with mobile only service and 109 million in this larger group I'm calling mobile-centric.
