Percentage of individuals using the internet to interact with public authorities. Data given in this domain are collected annually by the National Statistical Institutes and are based on Eurostat's annual model questionnaires on ICT (Information and Communication Technologies) usage in households and by individuals. The survey comprises questions at household level and individual level. The population of households consists of all private households having at least one member in the age group 16 to 74 years. The population of individuals consists of all individuals aged 16 to 74 (on an optional basis some countries collect separate data on other age groups, individuals aged 15 years or less, aged 75 or more). Regional breakdowns have been provided on a voluntary basis for 2006 and 2007 according to NUTS1 or NUTS2 by several countries. Starting from 2008, the collection of NUTS1 breakdowns is obligatory (regional breakdowns for all countries are available) while NUTS2 breakdowns are still optional.
