OECD Broadband Table - penetration per household

For what its worth - bear in mind household penetration is now less relevant than speed and data caps. There's a new ECTA scorecard for European broadband too. Netherlands first, from Denmark - at 38% or so, but you can throw your hat over most G7 countries at 24-29%. But the fibre tables (see below) show that Sweden easily outpaces Netherlands and Denmark for penetration, though put in the shade by East Asia.
