Furthermore, gender units can play an important role in gender sensitization training as well as in training on how to avoid gender bias in data collection. Through their contacts with national machineries for women and non-governmental organizations, gender units and gender focal points can facilitate communication between the producers and some of the end users of gender statistics (United Nations, 2006). These units can provide information to users and help them to understand the uses of existing statistics. The development of methodological materials on gender statistics has a rather short history.
