Questionnaire


Mobile Comparable Performance Indicators Initiative

• Just over 2 in 5 respondents in this UK survey claimed to use a mobile phone. 
• The most popular place from which calls are made was 'in buildings' with almost 9 in 10 mobile users ever making calls from here, and about 4 in 10 claiming to make most of their calls from here.  The least popular location for making calls was on the train or bus.
• About 2 in 3 mobile users claim to ever make calls from their car, van or lorry, but only a 1 in 4 say this is where they make the majority of their calls from.
• Just under a quarter of mobile users claimed to use any form of hands-free car kit, and about 7% use a car kit with a specially fitted external antenna.

Introduction
CMU commissioned research agency Ipsos-RSL to carry out some questions on their 'Capibus', a weekly omnibus survey amongst a sample of 2177 adults aged 15+, representative of the adult population across the UK.

The questions asked about general mobile phone usage, locations where customers make calls from and use of in-car kits.  The results are available with the following information - gender, age, social grade,ethnicity, working status, children in household, income, number in household, region, acorn classification, car ownership, use of telephone banking, internet at home, internet at work, type of mobile phone usage.  For further details contact Karen Metcalfe x8918.

Results

Mobile phone usage
Of the 2177 adults surveyed, 43% owned or had use of a mobile or in-car phone.  Of those using mobiles, 60% was personal use only, 7% business only and 31% for both business and personal.

Personal only usage was highest amongst the young (aged 15-34), higher social grades (ABC1s), high income groups (over £17.5k), and larger households with children.

Business and personal usage was highest amongst men, AB social grades, and those working full time with annual incomes of over £25k.

There were few demographic differences amongst the business only users.

Use of hands-free car kit
All mobile phone users were asked whether they, or anyone in their household, used nay special equipment which enables them to use their mobile phone when driving without holding the phone.

Just under a quarter (23%) of all mobile phone users claimed to use any form of hands-free car kit.  This rose to about a third amongst respondents using their phone for any business purposes.  Also more likely than average to use a kit were men, the AB social grades, those working full-time, and the high income bands.

Just under a third of car-kit users have an specially fitted external antenna on the car.  This equates to about 7% of mobile phone users.  This was higher amongst business users and lower amongst personal users.
