世論 What Japan Thinks

As mobile phone’s memory capacities increase, our need to remember phone numbers decreases. To find out in detail, iShare performed a survey into mobile phone dependence.

Demographics

Between the 11th and 13th of March 2008 889 members of the free email forwarding service CLUB BBQ completed an internet-based questionnaire. 54.6% were male, 23.2% were in their twenties and 76.7% in their thirties. 47.9% were married, and 22.9% lived alone. The respondents were pre-screened so everyone had a mobile phone.

I can only remember the last four digits of my mobile phone, my full home number, but I haven’t a clue what my wife’s is! I struggle to remember my work number, and I haven’t the slightest idea what my own personal extension number is!
