A/RES/50/81 Page 29 monitoring issues and trends and for evaluating progress achieved in implementing the Programme of Action. Special attention should be directed towards building national capacities and institutions regularly to collect and compile socio-economic data series that are both cross-sectional and disaggregated by cohort. To this end, interested centres and institutions may wish to consider the possibility of jointly strengthening or establishing, in cooperation with the United Nations, networks concerned with collection of data and publication of statistics and to realize thereby greater economies of scale in the development and dissemination of statistics in the field of youth. 127. Major contributions related to data and statistics in the field of youth are currently being made by the United Nations. Such contributions include the socio-economic data collection and statistical development activities of the Statistics Division of the Department for Economic and Social Information and Policy Analysis of the Secretariat; the youth policies and programmes information activities of the Division for Social Policy and Development of the Department for Policy Coordination and Sustainable Development of the Secretariat; the educational and literacy data collection activities of the United Nations Educational, Scientific and Cultural Organization; and the youth advisory networks of the United Nations Environment Programme. Concerned bodies and agencies of the United Nations system are urged to explore ways and means of achieving greater coherence in data collection and the publication of statistics. This could include programme planning and coordination on an inter-agency basis. For example, the data bank programme on adolescent health of the World Health Organization is coordinated with the work of the Statistics Division of the Secretariat. Other bodies and agencies of the United Nations system are invited to contribute data in their respective areas of expertise to an integrated socio-economic data bank on youth. For instance, the international drug abuse assessment system of the United Nations International Drug Control Programme is urged to consider including a component on youth and drugs. An inventory of innovative youth policies, programmes and projects could be coordinated and made available to interested users by the Department for Policy Coordination and Sustainable Development. Other topics that could be considered for joint action include juvenile delinquency, runaways and homeless youth. 128. Public information and communications are equally important in building awareness of youth issues, as well as a consensus on appropriate planning and action. The bodies and organizations of the United Nations system concerned are urged, as a matter of priority, to review publications currently produced and to identify ways in which these publications can better promote the Programme of Action and areas in which they may need to be complemented through the production of leaflets and posters in connection with special events. 129. To encourage widespread awareness of and support for the Programme of Action, Governments, non-governmental organizations and, as appropriate, the private sector, are urged to consider the possibility of preparing both printed and audiovisual materials related to areas of concern in the Programme of Action. This could be carried out with the assistance of and in cooperation with the United Nations and materials could be disseminated through United Nations public information channels. In addition young people and youth organizations are urged to identify and plan information activities that focus on priority issues, which they would undertake within the context of the Programme of Action. /...
