Most U.S. households have ditched landlines for mobile phones
A recently released survey from the Centers for Disease Control and Prevention (PDF) estimates that during the second half of 2016 50.8 percent of U.S. households were wireless only. That’s up from 48.3 percent during the same time period in 2015—a rise of 2.5 percentage points.
The story behind the story: It might seem odd to hear that the CDC is tracking phone usage, but there’s actually a good reason for it. Every year, the CDC conducts a face-to-face survey with 40,000 households called the National Health Interview Survey. Since 2003, the NHIS has monitored what kind of phone connectivity respondents had: landline or mobile. This data gives the CDC useful information that correlates to the health status of people without landlines.
Cutting the cord
But beyond the health implications, the CDC’s phone data tracking is useful to monitor the trend of households going mobile only. The CDC’s findings line up with financial reports from telecom providers that are a seeing a decline in landline phone revenue, as Fortune reported.
