秘书长致辞2015年10月20日
　　好的数据和统计对社会中所有行为体作出知情决策必不可少。联合国大会在2014年通过了旨在促进公民公共信息权的《官方统计基本原则》，对此予以明确承认。
　　随着各国和各种组织开始执行雄心勃勃的2030年可持续发展议程，可靠而及时的统计数据和指标比以往任何时候都更加重要。因此，今年世界统计日的主题是“优化数据，改善生活”。
　　我们需要确保将每一个人、特别是最贫穷和处境最不利的人都列入统计范围。每个孩子的出生都应得到登记。每次疾病的发生都应记录在案，无论地点有多遥远。我们需要本地数据和统计，确保每个儿童都能获得教育机会，我们也需要全球数据和统计，用于监测气候变化的总体影响。
　　在过去15年中，很多国家在其国家统计局的领导下，为加强本国的统计能力付出了大量努力。世界各地的2010年人口和住房普查、各类国内调查方案和行政管理数据都有助于改进用于监测千年发展目标进展的信息库，并为成功实现各项目标作出了重大贡献。
　　近70年来，联合国的统计委员会始终领导着全球统计系统。委员会通过制定标准和准则，创造出一种语言，使我们能在全球范围内交流数据和分享实际经验。如今，委员会已准备好在制定和实施可靠的可持续发展目标全球计量程序中发挥关键作用。
　　然而，对可持续发展目标成功与否进行监测的各项要求即使对最发达国家也是重大挑战。我们需要一场数据革命。我们需要加强统计能力，并挖掘新技术的潜力。我们需要数据编制者和使用者、学术界和研究中心、私营部门和民间社会的贡献和专长。
　　值此世界统计日之际，我敦促所有伙伴和利益攸关方携手合作，确保进行必要的投资、建立充分的技术能力、探索新的数据来源以及采用创新方法，使所有国家都获得实现可持续发展所必需的综合信息系统。
Secretary-General’s MessageGood data and statistics are indispensable for informed decision-making by all actors in society.  This was explicitly acknowledged in 2014, when the United Nations General Assembly adopted the Fundamental Principles of Official Statistics to promote citizen’s entitlement to public information.
As countries and organizations embark on implementing the ambitious 2030 Agenda for Sustainable Development, reliable and timely statistics and indicators are more important than ever.  For that reason, World Statistics Day this year is being observed under the theme “Better data, better lives.”
We need to ensure that everyone is counted, especially the most poor and vulnerable.  No child’s birth shall remain unregistered.  No incidence of disease, no matter how remote the location, shall remain unrecorded.  We need local statistics to ensure that every child has access to education and we need global statistics to monitor the overall effects of climate change.
Over the past 15 years, many countries have made considerable efforts to strengthen their national statistical capacity under the leadership of their national statistical offices.  The 2010 Population and Housing Census Round, numerous national survey programmes, as well as administrative data, have contributed around the world to improving the information base for monitoring progress towards the Millennium Development Goals, and have contributed significantly to their success.
At the United Nations, the Statistical Commission has for almost 70 years led the global statistical system.  Through its standards and guidelines, the Commission has created a language which enables us to communicate data and to share practical experiences globally.  Today, the Commission stands ready to play a key role in developing and implementing a solid global measurement process for the Sustainable Development Goals.
However, the monitoring requirements for the success of the Sustainable Development Goals pose a significant challenge to even the most developed countries.  We need a data revolution.  We need to strengthen statistical capacity and tap into the potential of new technology.  We need the contributions and expertise of data producers and users, academia, the private sector and civil society. 
On this World Statistics Day, I urge all partners and stakeholders to work together to ensure that the necessary investments are made, adequate technical capacity is built, new data sources are explored and innovative processes are applied to give all countries the comprehensive information systems they need to achieve sustainable development.
