The UK has the ninth highest fixed line broadband penetration rate among 34 OECD countries, down from 8th last year, the latest table reveals.
Each year, the Organisation for Economic Co-operation and Development ranks 34 countries (each of which support a market economy and democracy) on a variety of factors, including broadband penetration.
Between December 2011 and June 2012, the UK slid to ninth position in the chart, with 33.6 people out of every 100 subscribing to fixed line broadband services.
It is some way behind the table topper, Switzerland, which has 41.6 subscribers per 100 inhabitants, though the UK's penetration did improve by 2.3 per cent over the period, compared with Switzerland's 2.2 per cent.
In terms of the number of broadband customers, the UK remains in the top five, with 21 million customers, though the US is still way out in front, with more than 88 million broadband subscribers.
Wireless broadband subscriptions place the UK even higher in the list, putting it in fourth place with 37. 6 million customers, compared with 237.8 million in the table topper, the US.
The UK remains way behind when the percentage of fibre connections is taken into account, however, with just 2.77 per cent of all subscribers benefiting from superfast services, compared with a huge 65 per cent in Japan, which tops the OECD table.
