The ITC Policy Evaluation Project started its first project, the ITC 4 Country Project in 2002, to measure the psychosocial and behavioural factors of smoking in Australia, Canada, the United Kingdom, and the United States. The ITC team has collected eight waves of 4 Country survey data. The other ITC countries joined the project at different times after the 4 Country project began, and therefore are in different waves of data collection.
