Survey on Private Usage of Information and Communication Technologies (ICT)

Summary

The ICT-Survey records data on the dissemination of information and communication technologies (ICT) and on the use of the internet in private households. Among others, it provides information on the usage of ICT for educational activities and on attending computer training courses. The ICT-survey has a large sample. As it is conducted every year, the ICT-survey allows for trend analyses over a longer period. Data is harmonized between the EU-member states, so the results are directly comparable. Documentation and metadata in German are available via internet. The survey contains only few context variables, mainly socio-economic and socio-demographic items. There is no Scientific Use File, data can only be used by on-site access and remote data processing. Data and documentation are available in German only.

Coverage of main and cross-cutting topics
Detailed Study: Study on dissemination of information and communication technologies (ICT) and on the use of the internet in private households. It also covers socio-economic and socio-demographic items, items on infrastructure of communication technology in private households, information on the way, frequency and purposes of the internet usage (e.g. E-government, E-commerce, E-learning), information on scruples and barriers to the use of new technologies (Source: Statistisches Bundesamt 2012.

Data quality

Entry errors if applicable
• Sampling error: quota sample, no sampling error • Non-sampling error: questionnaire checks before data entry, computer-assisted plausibility checks • Non-response: quota sample, therefore no non-response results on base of observation units, less than 5 per cent non-response rate on base of item units.

Breaks
There was a larger sample size in the years 2006 to 2012, than in the years 2003 to 2005.
