Codes and Frequencies
ICT reported used information communication technology, including computer, mobile phone, or web, during the activity.
Users should note that in some recent surveys, the diary included a column marking whether the diarist used ICTs. If such a column is available, then it was used to create this 0/1 marker variable. In many cases, however, this information could only be identified from the activity code list.
In cases where the identification of ICT use is available in more than one format (a dedicated column as well as in activity codes), all forms of available information were used to create this marker. As is the case with the mode of transport, where the diarist may not write down the word "commute" in the activity column if they have written "drove car to work" in the location column, some diarists similarly might write "internet banking" as their activity but not bother to tick the used a computer box. Nevertheless, such an identification of the activity does give use sufficient information to know that the diarist used ICTs during this episode.

In 1985, 1992-1994, 1994-95 and 1998-2001, we can only identify this information from the activity codes.
