However, due to the relatively resource-intensive nature of Time Use Surveys, these are generally conducted at about five-yearly intervals (with the exception of the United States). In interim years or where their implementation is not feasible, data on unpaid work and use of time can be collected through survey instruments with lower collection and response burden, e.g. "light" diaries with pre-coded time use categories (UNECE, 2013). A number of initiatives have been launched by national statistical offices and international organisations to spread awareness of gender-based violence.
