for example some women s activities and contribution to the economy and society are not adequately captured in statistics if old concepts of work and labour force which do not take into account all forms of work are used see for example the section entitled work in chapter ii for example gender statistics in agriculture should be based on an adequate coverage of all agricultural holdings including smallholdings where women are predominant should include information on farm labour disaggregated by sex age and other social and economic characteristics and should cover aspects of management and ownership of agricultural resources at the most disaggregated level possible such as the subholding and individual levels furthermore new concepts and new methods of data collection should be used for the production of gender statistics for example recent methodological developments in timeuse surveys and violence against women surveys and changes towards more comprehensive statistics in national accounts so that unpaid work is covered should be integrated in the production of national statistics
