Here is a <a href=\"http:\/\/www.cdc.gov\/nchs\/data\/nhis\/earlyrelease\/wireless200805.htm\">direct link to the report<\/a>.<\/p>\n<p>The key findings ar :<\/p>\n<ul>\n<li>1 in 6 homes (~15%) are &#8220;Cell Phone Only&#8221; &#8212; that is they simply DO NOT have a landline.<\/li>\n<li>1 in 8 homes (~13%) receive &#8220;almost all&#8221; calls on their cell phone even though they have a landline<\/li>\n<\/ul>\n<p>If you just look at those two numbers, ~30% of households essentially rely on cell phones as their primary voice communication device. And this is the last 6 months of 2007. I can only imagine, the first six months of 2008 this has only gone up, especially with the launch but both Sprint and AT&amp;T for &#8220;unlimited&#8221; minutes. I can also say from personal anecdotal evidence, I finally convinced my wife what we really don&#8217;t need a land line &#8212; so my own residence does not have a landline anymore. We were getting too many telemarketers anyways.<\/p>\n<p>The other paradigm shift that is happening is that businesses (brick n mortar) are accepting emails as the preferred communication model &#8212; Eastside Bavarian where I change oil emails me and I can email them to request an appointment &#8212; they even send me a <a href=\"https:\/\/www.questionpro.com\/blog\/surveys\/\">survey<\/a> after every service! I hardly ever talk to my mortgage broker or banker anymore &#8212; we simply rely on email to communicate with each other.<\/p>\n<p>The third component that is facilitating this shift is the &#8220;Smart Phone&#8221; market is expanding rapidly &#8211; Blackberry, iPHones etc. All these phones are becoming communication assistants rather than being a phone. I use my iPhone for email, text and phone (in that order.)<\/p>\n<p>Now, what does all this mean for <a href=\"https:\/\/www.questionpro.com\/blog\/what-is-research\/\">research<\/a>? &#8212; The big issue is that of<a href=\"https:\/\/www.questionpro.com\/blog\/sampling-error\/\"> sample bias<\/a>. Traditionally <a href=\"https:\/\/www.questionpro.com\/blog\/execute-online-research\/\">online research<\/a> was considered as an after-thought to phone based research. Now with potentially a 30% sample bias error, <a href=\"https:\/\/www.questionpro.com\/features\/telephone-surveys-CATI.html\">phone surveys<\/a> will become increasingly difficult to conduct and more importantly pass the sample bias validation test. That is the general conclusion of the report also.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The National Center for Health Statistics put out some numbers on surveying &#8212; The general conclusion is that using &#8220;landline&#8221; [&hellip;]<\/p>\n","protected":false},"author":104,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[250,203],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Telephone surveys - inching to the to the deadpool?
