A study from Centers for Disease Control and Prevention (CDC) has indicated that almost 15 per cent of the households in the US has no land-line in their house, surviving solely on mobile phones. The study found that 14.7 per cent of US citizens are solely reliant on their mobile phone.
Why is this anything to do with the CDC? because up until now the company has performed its larger surveys exclusively on landlines. These findings make those surveys much less relevant, both for the CDC and any group using telephones to perform surveys.
“These findings are important to CDC because many of our larger surveys are done on calls to land-line phone numbers. All of those adults with only cell phones are being missed in these surveys.” – Stephen Blumberg, health scientist – CDC.
It’s a statistic that will make many survey companies rethink their policies.
For stats fans, the state with the highest number of no land-line households is Oklahoma, with 26.2 per cent, for some reason streets ahead of Delaware with the least, 4 per cent.
