[Air-l] Help needed about statistics

Hi dear colleagues, I am preparing an article on internet penetration. I have been looking for some data because I am interested in getting the percentage of households connected to the Internet over the total of households and the percentage of households with a broadband connection over the total of households. I would like to get the statistics from one source, because otherwise comparison among different sources is not very accurate. The countries in which I am interested in are Korea, USA, Hong King, Singapur, Taiwan, China, New Zealand, Norway, Australia. Thank you very much in advance, Mª Isabel Diaz de Isla IN3-UOC
