1. The document discusses how the rise of big data and digital technologies has created the "Petabyte Era" where massive amounts of data can be analyzed without models or theories to explain human behavior. 2. It argues that statistical agencies must evolve from simply providing information to building knowledge by developing new communication strategies to effectively disseminate data to the public and maintain trust in official statistics. 3. To remain relevant, statistical organizations need to embrace new technologies like web 2.0 and engage with users in two-way conversations to ensure data is presented in ways people understand and relate to their interests.

- 3. The Petabyte Era(1) Sixty years ago, digital computers made information readable. Twenty years ago, the Internet made it reachable. Ten years ago, the first search engine crawlers made it a single database. Now Google and like-minded companies are sifting through the most measured age in history, treating this massive corpus as a laboratory of the human condition. They are the children of the Petabyte Age. At the Petabyte scale, information is not a matter of simple three- and four-dimensional taxonomy and order but of dimensionally agnostic statistics. It calls for an entirely different approach, one that requires us to lose the tether of data as something that can be visualized in its totality. It forces us to view data mathematically first and establish a context for it later.
- 4. The Petabyte Era(2) Speaking at the O'Reilly Emerging Technology Conference this past March, Peter Norvig, Google's research director, offered an update to George Box's maxim: "All models are wrong, and increasingly you can succeed without them." This is a world where massive amounts of data and applied mathematics replace every other tool that might be brought to bear. Out with every theory of human behavior, from linguistics to sociology. Forget taxonomy, ontology, and psychology. Who knows why people do what they do? The point is they do it, and we can track and measure it with unprecedented fidelity. With enough data, the numbers speak for themselves.

Some evidence 69%of Europeans think that it is necessary to know economic data 53% of Europeans are not able even to guess the GDP growth rate in their country. 8% know the right figure 45% of Europeans do not trust official statistics In the US the five main TV channels report GDP figures only in the 46% of cases, the 27 main newspapers in the 39% of cases 40% of Americans never heard of official GDP data or the source agency

- 8. The web 2.0revolution and official statistics Some evidence: 95% of those who use Google do not go beyond the first page of occurrences; once they reach a site, 95% of users do not click more than three times to find what they want; the way in which “discovery metadata” are structured is fundamental, but these metadata have nothing to do with the intrinsic quality of the information provided; Web 2.0 tends to transform the “consumer” of a particular information/service provided via Internet into a “prosumer”; new approaches to discovery are based on people’s opinions.
- 9. How is informationdisseminated? As Einstein said, “information is not knowledge”: knowledge is a complex and dynamic process involving cognitive mechanisms and the person’s interest plays a key role in activating the cognitive mechanism. The “epidemiologic” approach states that information is spread like a virus in a society. Therefore, data providers need to reach as many people as possible at the beginning of the chain, to “vaccinate” them against the “ignorance disease”. To do that, they have to: disseminate information relevant to people; present it in a way that people can relate it to their own interests; use language/tools coherent with those used by people in other contexts.

- 14. Opportunities and risksReliable statistics cannot be generated using “collective intelligence”, but this approach can have a huge impact on the way in which statistics are perceived or used. New keywords: Legitimacy, Trust, Authority, Credibility Great challenge, but also a key opportunity, for data providers to develop a new communication strategy to reach/convince “communities” about the quality of existing sources (UN principle 4: “The statistical agencies are entitled to comment on erroneous interpretation and misuse of statistics”). If web 2.0 is marketplace for discussion, should statistical institutions create discussion sites about the quality of data used in the public domain, including that of their own data? Is there a risk to open a “Pandora’s box”?

Some people may argue that all these “signals” are part of a “storm” and not as indicators of a paradigm shift: therefore there is no need for a radical (and quick) change in the way statistics are disseminated and communicated. According to several people, we are facing a real paradigm shift and radical changes are necessary to stay on the market I believe that statistical data providers need to evolve from “information providers” to “knowledge builders”

- 30. A must forthe future of statistics This revolution comes from the advances in technology, rather than from a new statistical technique: because of ICT changes, data are becoming a “commodity” and statistical analyses are no longer a kind of methodology whose results are accessible to a small audience, but a key process to produce knowledge for all people. In this context, communication is not an just appendix of the core business focused on data production, but a key function that can determine the success or the failure of an official data provider. Be open to the dialogue with users using the web 2.0 approach is not a choice anymore: it is a must, especially to ensure that new generations will look at official statistics as an authoritative source .

Back to thefuture La filosofia della statistica è la cognizione ragionata delle norme generali per ricercare, delle fonti a cui attingere, de’ sintomi per riconoscere, de’ principi per giudicare, degli usi a cui servono gli elementi relativi allo stato delle nazioni. Munito di queste cognizioni, il filosofo descrive un paese con quell’esattezza che si usa da un pittore nel fare il ritratto d’una persona; lo giudica con quell’imparzialità che si pratica dai tribunali verso gli accusati; ricerca le cause delle malattie e i modi di guarirle. Melchiorre Gioia, 1839
Editor's Notes
- #4 24/05/11 Statistics represent an essential input into the analytical work of the Organisation. Data are collected, mainly from Member governments, and are converted, as much as possible, onto an internationally comparable basis. Statistics are then made available for internal use and most of them are then published in both printed and electronic form for use by the general public. In collaboration with statisticians from member countries and other international organisations, the OECD develops data systems to respond to policy concerns in areas such as national accounts, environment, and service industries.

- #16 “ Noi Italia – 100 indicators to understand Italy ” contains 120 indicators for 19 thematic sectors ranging from economic, social, demographic and environmental fields. This product represents an innovative goal from the statistical point of view as 120 indicators have been calculated starting from basic data, coming from different sources. Moreover, an innovative solution that offers both a dynamic and interactive way for graphical visualization of spatio-temporal data and the ability to link free texts to such models has been implemented.
- #17 The application allowed us to set easily the parameter for the two main graphic components used in “Noi Italia 2011” (Map and Histogram) according to: - the default indicators chosen to be displayed; - features that we offered to the end user through the application;
- #18 In August 2010 Istat and NComVA conclude a Technical Services Agreement to use Statistics eXplorer at Istat In January 2011 Istat carries out the first online product based on Statistics eXplorer: “ Noi Italia – 100 indicators to understand Italy ” , a publication which provides data by regions, enabling users to exploit the main features of the application. Ultimate goal is to develop Istat.eXplorer as the corporate GeoAnalytics Visualization environment.
