Stuffed full of stats. Much more on recycling than cycling.
In "large urban areas" 40% of households don't have access to a car.
Fewer than 50% of 17-25 year olds hold a full driving licence.
So lots of potential for people who might like/want to cycle!
Broadband access has gone up from 40% to 70% in last 8 years - so perhaps more people stay in...
In 2009 the answer to "How adults usually travel to work or education" was 2% for bicycle. For this year the Household Survey says -
"Transport Scotland publishes the SHS transport and travel data directly. The Transport and Travel in Scotland publication (http://www.scotland.gov.uk/Topics/Statistics/Browse/Transport-Travel/Tatis) will include information on households' access to cars and bikes, frequency of driving, modes of travel to work and school, use and opinions of public transport and access to services. Transport and Travel in Scotland 2010 is scheduled for publication 31st August 2011."
