Tim Berners-Lee and the World Wide Web’s 29th birthday

Just two quoted sentences as a suggestion to read the whole story here:

The divide between people who have internet access and those who do not is deepening existing inequalities — inequalities that pose a serious global threat.’

‘The web that many connected to years ago is not what new users will find today.’


Synchronously Visualized

Once again:  the New York Times presents an innovative graphic, which you always want to watch again and again.

It’s this Downhill Race at the Olympics:

For Statistics?

It would be exciting to follow such visualizations, e. g. on changes in unemployment, GDP etc. of different countries from today-minus-x to today.

Easy-to-understand Statistics for the Public

In a recently published EUROSTAT publication, the authors demand innovative forms of communication from public statistics in order not to lose their socially important role. Among other things, they demand ‘…. to tell stories close to the people; to create communities around specific themes; to develop among citizens the ability to read the data and understand what is behind the statistical process.’

Telling Stories

The UNECE hackathon that has just been completed responds to this challenge.
‘A hackathon is an intensive problem-solving event. In this case, the focus is on statistical content and effective communication. The teams will be challenged to “Create a user-oriented product that tells a story about the younger population”. During the Hackathon, fifteen teams from nine countries had 64.5 hours to create a product that tells a story about the younger population. The teams were multidisciplinary – with members from statistical offices and other government departments. The product created should be innovative, engaging, and targeted towards the general public (that is, not specialists). There was no limit on the form of the product, but the teams had to include a mandatory SDG indicator in the product.
The mandatory indicator was “Proportion of youth (aged 15-24 years) not in education, employment or training” SDG indicator (Indicator 8.6.1).‘ (Source)


And the hackathon shows impressive results, even if only a few organisations have participated.

The four winners are:

My Favourites

My favourites are number 3 from the National Institute of Statistics and Geography (INEGI-Mexico) and number 2 from the Central Statistical Office of Poland.


The Mexican solution…

…is aesthetically pleasing and easy to use. The interaction is left to the user and can be individually controlled by him/her in the speed.

The diagrams do not stand alone, but are explained by short texts while scrolling.

The results are not just being accepted. Rather, the concepts are explained and questioned – statistics are presented with the methodological background.

The Polish solution…

…starts with a jourmalistic approach. Here too, the interactivity can be controlled by the user at the desired speed.

At the end, the authors also seek direct contact with the users; a quiz personalizes the statistical data and gives an individual assessment of where the users stand personally with regard to these statistics.

Success Factors

The two applications mentioned above combine decisive user-friendly features:
– visually attractive,
– easy-to-understand navigation that can be controlled by the user according to his needs,
– the journalistic approach,
– concise and instructive explanations,
– personalization,
– hints on the methodological background.

Many of the other applications show the frequently encountered weaknesses: Too much information should be provided, no courage to leave something behind and concentrate on the most important elements. And this leads to long texts and complex navigation with the effect that users quit quickly.

The Good, the Bad and the Ugly

Communication of statistics in times of fake news

In a recent paper Emanuele Baldacci, (Director, Eurostat) and Felicia Pelagalli, (President, InnovaFiducia) deal with the ‘challenges for official statistics of changes in the information market spurred by network technology, data revolution and changes in information consumers’ behaviours’ (p.3)

Three scenarios

The status-quo or bad scenario:

‘Information will continue to be consumed via multiple decentralized channels, with new information intermediaries emerging through social platforms, digital opinion leaders, technologies that reinforce belonging to peers with similar profiles and backgrounds, including in terms of beliefs.’  … ‘Under this scenario it is likely that increased competition from alternative data providers will put pressure on the official statistics position in the information ecosystem and lead to drastic reduction of public resources invested in official statistics, as a result of the perceived lack of relevance.’ (p.8)


The ugly scenario:

‘Big oligopoly giants will emerge by integrating technologies, data and content and providing these to a variety of smaller scale platforms and information intermediaries, with limited pricing power for further dissemination. In this scenario, data generated by sensors and machines connected to the network will increasingly create smart information for individuals. However, individuals will not participate in the data processing task, but will be mostly confined to crowdsourcing data for digital platforms and using information services.’
‘In this scenario, official statistics will be further marginalized and its very existence could be put in jeopardy. More importantly, no public authority with significant influence could be in charge of assessing the quality of data used in the information markets. Statistics as a public good may be curtailed and limited to a narrow set of dimensions. …  Official statisticians will appear as old dinosaurs on the way to extinction, separated from the data ecosystem by a huge technology and capability gap.’ (p.9)


The good scenario:

The authors do not stop here. They also see a good scenario, but a scenario that implies a huge engagement.

This scenario is ‘predicated on two major assumptions.
First, the information market will be increasingly competitive by sound regulations that prevent the emergence of dominant positions in countries and even more important across them.
Second, official statistics pursue a strong modernization to evolve towards the production of smart statistics, which fully leverage technology and new data sources while maintaining and enhancing the quality of the data provided to the public.
In this scenario, official statistics will generate new more sophisticated data analytics that cater to different users by tailored information services. It uses network technologies (e.g., blockchain, networks) to involve individuals, companies and institutions in the design, collection, processing and dissemination of statistics. It engages users with open collaborative tools and invests heavily in data literacy to ensure their usability. It strengthens skills and capacity on statistical communication to help users understand in transparent manners what are the strengths and limitations of official statistics.’ (p. 9/10)


Actions needed to face the challenges ahead

The good scenario already depicts some needed actions to be taken by official statisticians. The authors conclude with proposals that are not really new, ideas that have been on the table for some time but are not so easy to implement.

‘It is important to change mindsets and practices which have been established, in order to put in contact the citizens with official statistics, to make data accessible, to expand the understanding of their analysis, to support individuals, business and institutions in the decision-making process.

The key issue is how to be authoritative and to develop quality knowledge in the new and changing information market. It is important to know the rules and languages of the media platforms used for communication; to overcome the technicalities; to tell stories close to the people; to create communities around specific themes; to develop among citizens the ability to read the data and
understand what is behind the statistical process. In summary, put people at the center (overused phrase, but extremely valuable):
⎯ communicate statistics through engaging experiences and relevant to the people who benefit from them;
⎯ customize the content;
⎯ adopt “user analytics” to acquire the knowledge of the “users” through the analysis of data (web and social analytics) and the understanding of people’s interaction with the different platforms.’ (p.11)

And the concluding words call for external assistance:

‘It will be essential for statisticians to build more tailored data insight services and team up with communication experts to play a more proactive role in contrasting fake news, checking facts appropriately and building users’ capacity to harness the power of data.’ (p.12)






Corporate nieuws

Eurostat’s biennial scientific conference on New Techniques and Technologies for Statistics (NTTS) is over, a labyrinth of a website is online and tons of documents are somewhere published.

CBS Corporate nieuws summarizes the important trends discussed:
1) New data sources and the consequences
2) The importance of a proactive communication
3) Big Data and algorithms in official statistics

Corporate websites

Why taking this information just from CBS (the Dutch Statistical Office)? Because CBS Corporate nieuws is an excellent example of the second trend: proactive communication, proactivity in delivering (statistical) information to users. The website makes corporate information public and gives insights into activities of CBS and statistics. You see topics …

… and the people behind it.

The target public of this corporate website are enterprises, administrations, journalists, students and whoever may be interested.

A shorter English version is integrated into the CBS website.

Corporate websites like CBS’ are not quite usual. They are resource consuming but are probably very good in helping to understand statisticians’ mission and work .. and in motivating employees.





Learning by Doing

The New York Times did it after the election, in January 2017: You Draw It, Learning Statistics by drawing and comparing charts.

‘Draw your guesses on the charts below to see if you’re as smart
as you think you are.’


And Bayerischer Rundfunk did it before the election, in April 2017.

This kind of giving information is an excellent strategy to foster insights and against forgetting. And it’s an old tradition in didactics. 360 years ago Amos Comenius emphasized this technique in his Didactica Magna:

“Agenda agendo discantur”


There is no New Thing under the Sun – Yes and No

Twitter reminded me that there’s #NTTS2017 going on, Eurostat’s biennial scientific conference on New Techniques and Technologies for Statistics (NTTS).

The opening session also focused on official statistics and its actual and future role in a world of data deluge and alt-facts. What will be Official Statistics in 30 years?
In Diego Kuonen’s presentation and discussion on ‘Big Data, Data Science, Machine Intelligence and Learning’ I could hear an answer to this question reminding me of a text in the Bible: “… that [thing] which is done is that which shall be done: and there is no new thing under the sun”.
And this not to be understood in a static but in a dynamic interpretation:
The work statistical institutions are doing today will be the same that they will do tomorrow … BUT a work adapted to the changing context.
The algorithms (understood in a broader sense as ‘a set of rules that precisely defines a sequence of operations ->‘) used in collecting, analyzing and disseminating data will be changing, manual work will / must be replaced by automation, robots. But the core role of being a trusted source of data-based and (in all operations) transparently produced information serving professional decision making will remain.
The challenge will be that these institutions
– are known,
– are noted for their veracity,
– are consulted
and with all this can play their role.
In this fighting to be heard humans will always play a decisive part.
That’s a clear message (as I understood it) of a data scientist looking ahead.
PS. A step towards automation consists of preparing and using linked data. See the NTTS 2017 satellite session “Hands-on workshop on Linked Open Statistical Data (LOD)”
