Wireless-only higher among low-income, minorities

Early results from the July–December 2012 National Health Interview Survey (NHIS) show that U.S. wireless-only homes continue to grow. According to NHIS:
“Nearly two in every five American homes (38.2%) had only wireless telephones during the second half of 2012 – an increase of 2.4 percentage points since the first half of 2012.”
An additional 16 percent who have landlines receive all or nearly all their calls on wireless. So, 54 percent mostly or exclusively use wireless.
But these numbers aren’t spread evenly among the population. 62 percent of young people (25-29) have wireless only.
More affluent households tend to have both landline and wireless.
And, wireless only predominates among minority populations.
