52.5% of USA households are now wireless-only (do not have a landline phone). An additional 15.1% of US households are wireless-mostly. A wireless-mostly household is defined as one that has a landline phone, but takes all or almost all of their calls on a wireless device. Together, 67.6% of U.S. households are now either wireless-only or wireless-mostly – therefore these respondents are unlikely to be reached on a landline.

Unfortunately, many vendors only can provide landline phones and this is not representative. In order to maintain representative coverage, you MUST include both wireless and landline phones.

The following chart shows the overall breakdown of US households by telephone coverage:

So, if you purchase landline-only lists or append only landline phones to your data, you are missing out on a huge proportion of the population.
