Percentage of Regional Population Who Reads Books

Mon, 15 Nov 2021 19:00:00 +0100

The indicator is created from the Eurobarometer 79.2 survey’s GESIS datafile using regional subsamples. The regional subsamples were recoded to the NUTS 2016 regional boundary definitions with the regions R package. In the larger countries, where only NUTS1 level information was present (for example, in Germany and the United Kingdom), we imputed the NUTS1 territorial average values to the constituent NUTS2 regions.

We placed the authoritative copy with metadata on the Zenodo open repository.

A ‘dirty averaging’ was used to create regional averages, with scale national post-stratification weights to an expected value of 1. Al respondents who read at least one book in the previous 12 months were coded to have read a book.

This indicator was used in the Balázs Bodó, Dániel Antal, Zoltán Puha: Can scholarly pirate libraries bridge the knowledge access gap? An empirical study on the structural conditions of book piracy in global and European academia, in Plos ONE (Published: December 3, 2020.)

How We Add Value to Public Data With Better Curation And Documentation?

Mon, 08 Nov 2021 09:00:00 +0000

In this example, we show a simple indicator: the Turnover in Radio Broadcasting Enterprises in many European countries. This is an important demand driver in the Music economy pillar of our Digital Music Observatory, and important indicator in our more general Cultural & Creative Sectors and Industries Observatory. We show a very similar example in our Green Deal Data Observatory with environmental R&D public spending in Europe.

This dataset comes from a public datasource, the data warehouse of the European statistical agency, Eurostat. Yet it is not trivial to use: unless you are familiar with national accounts, you will not find this dataset on the Eurostat website.

The data can be retrieved from the Annual detailed enterprise statistics for services NACE Rev.2 H-N and S95 Eurostat folder.

Our version of this statistical indicator is documented following the FAIR principles: our data assets are findable, accessible, interoperable, and reusable. While the Eurostat data warehouse partly fulfills these important data quality expectations, we can improve them significantly. And we can also improve the dataset, too, as we will show in the next blogpost.

Findable Data

Our data observatories add value by curating the data–we bring this indicator to light with a more descriptive name, and we place it in context with our Digital Music Observatory and Cultural & Creative Sectors and Industries Observatory. While many people may need this dataset in the creative sectors, or among cultural policy designers, most of them have no training in working with national accounts, which imply decyphering national account data codes in records that measure economic activity at a national level. Our curated data observatories bring together many available data around important domains. Our Digital Music Observatory, for example, aims to form an ecosystem of music data users and producers.

We added descriptive metadata that help you find our data and match it with other relevant data sources.

We added descriptive metadata that help you find our data and match it with other relevant data sources. For example, we add keywords and standardized metadata identifiers from the Library of Congress Linked Data Services, probably the world’s largest standardized knowledge library description. This ensures that you can find relevant data around the same key term (radio broadcasting) in addition to our turnover data. This allows connecting our dataset unambiguosly with other information sources that use the same concept, but may be listed under different keywords, such as Radio–Broadcasting, or Radio industry and trade, or maybe Hörfunkveranstalter in German, or Emitiranje radijskog programa in Croatian or Actividades de radiodifusão in Portugese.

Accessible Data

Our data is accessible in two forms: in csv tabular format (which can be read with Excel, OpenOffice, Numbers, SPSS and many similar spreadsheet or statistical applications) and in JSON for automated importing into your databases. We can also provide our users with SQLite databases, which are fully functional, single user relational databases.

Tidy datasets are easy to manipulate, model and visualize, and have a specific structure: each variable is a column, each observation is a row, and each type of observational unit is a table. This makes the data easier to clean, and far more easier to use in a much wider range of applications than the original data we used. In theory, this is a simple objective, yet we find that even governmental statistical agencies–and even scientific publications–often publish untidy data. This poses a significant problem that implies productivity loses: tidying data will require long hours of investment, and if a reproducible workflow is not used, data integrity can also be compromised: chances are that the process of tidying will overwrite, delete, or omit a data or a label.

Tidy datasets are easy to manipulate, model and visualize, and have a specific structure: each variable is a column, each observation is a row, and each type of observational unit is a table.

While the original data source, the Eurostat data warehouse is accessible, too, we added value with bringing the data into a tidy format. Tidy data can immediately be imported into a statistical application like SPSS or STATA, or into your own database. It is immediately available for plotting in Excel, OpenOffice or Numbers.

Interoperability

Our data can be easily imported with, or joined with data from other internal or external sources.

All our indicators come with standardized descriptive metadata, and statistical (processing) metadata. See our API

All our indicators come with standardized descriptive metadata, following two important standards, the Dublin Core and DataCite–implementing not only the mandatory, but the recommended descriptions, too. This will make it far easier to connect the data with other data sources, e.g. turnover with the number of radio broadcasting enterprises or radio stations within specific territories.

Our passion for documentation standards and best practices goes much further: our data uses Statistical Data and Metadata eXchange standardized codebooks, unit descriptions and other statistical and administrative metadata.

Reuse

All our datasets come with standardized information about reusabililty. We add citation, attribution data, and licensing terms. Most of our datasets can be used without commercial restriction after acknowledging the source, but we sometimes work with less permissible data licenses.

In the case presented here, we added further value to encourage re-use. In addition to tidying, we significantly increased the usability of public data by handling missing cases. This is the subject of our next blogpost.

How We Add Value to Public Data With Imputation and Forecasting

Public data sources are often plagued by missng values. Naively you may think that you can ignore them, but think twice: in most cases, missing data in a table is not missing information, but rather malformatted information. This approach of ignoring or dropping missing values will not be feasible or robust when you want to make a beautiful visualization, or use data in a business forecasting model, a machine learning (AI) applicaton, or a more complex scientific model. All of the above require complete datasets, and naively discarding missing data points amounts to an excessive waste of information. In this example we are continuing the example a not-so-easy to find public dataset.

In the previous blogpost we explained how we added value by documenting data following the FAIR principle and with the professional curatorial work of placing the data in context, and linking it to other information sources, such as other datasets, books, and publications, regardless of their natural language (i.e., whether these sources are described in English, German, Portugese or Croatian). Photo: Jack Sloop.

Completing missing datapoints requires statistical production information (why might the data be missing?) and data science knowhow (how to impute the missing value.) If you do not have a good statistician or data scientist in your team, you will need high-quality, complete datasets. This is what our automated data observatories provide.

Why is data missing?

International organizations offer many statistical products, but usually they are on an ‘as-is’ basis. For example, Eurostat is the world’s premiere statistical agency, but it has no right to overrule whatever data the member states of the European Union, and some other cooperating European countries give to them. And they cannot force these countries to hand over data if they fail to do so. As a result, there will be many data points that are missing, and often data points that have wrong (obsolete) descriptions or geographical dimensions. We will show the geographical aspect of the problem in a separate blogpost; for now, we only focus on missing data.

Some countries have only recently started providing data to the Eurostat umbrella organization, and it is likely that you will find few datapoints for North Macedonia or Bosnia-Herzegovina. Other countries provide data with some delay, and the last one or two years are missing. And there are gaps in some countries’ data, too.

See the authoritative copy of the dataset.

This is a headache if you want to use the data in some machine learning application or in a multiple or panel regression model. You can, of course, discard countries or years where you do not have full data coverage, but this approach usually wastes too much information–if you work with 12 years, and only one data point is available, you would be discarding an entire country’s 11-years’ worth of data. Another option is to estimate the values, or otherwise impute the missing data, when this is possible with reasonable precision. This is where things get tricky, and you will likely need a statistician or a data scientist onboard.

What can we improve?

Consider that the data is only missing from one year for a particular country, 2015. The naive solution would be to omit 2015 or the country at hand from the dataset. This is pretty destructive, because we know a lot about the radio market turnover in this country and in this year! But leaving 2015 blank will not look good on a chart, and will make your machine learning application or your regression model stop.

A statistician or a radio market expert will tell you that you know more-or-less the missing information: the total turnover was certainly not zero in that year. With some statistical or radio domain-specific knowledge you will use the 2014, or 2016 value, or a combination of the two and keep the country and year in the dataset.

Our improved dataset added backcasted (using the best time series model fitting the country’s actually present data), forecasted (again, using the best time series model), and approximated data (using linear approximation.) In a few cases, we add the last or next known value. To give a few quantiative indicators about our work:

Increased number of observations: 65%
Reduced missing values: -48.1%
Increased non-missing subset for regression or AI: +66.67%

If your organization is working with panel (longitudional multiple) regressions or various machine learning applications, then your team knows that not havint the +66.67% gain would be a deal-breaker in the choice of models and punctuality of estimates or KPIs or other quantiative products. And that they would spent about 90% of their data resources on achieving this +66.67% gain in usability.

If you happen to work in an NGO, a business unit or a research institute that does not employ data scientists, then it is likely that you can never achieve this improvement, and you have to give up on a number of quantitative tools or visualizations. If you have a data scientist onboard, that professional can use our work as a starting point.

Can you trust our data?

We believe that you can trust our data better than the original public source. We use statistical expertise to find out why data may be missing. Often, it is present in a wrong location (for example, the name of a region changed.)

If you are reluctant to use estimates, think about discarding known actual data from your forecast or visualization, because one data point is missing. How do you provide more accurate information? By hiding known actual data, because one point is missing, or by using all known data and an estimate?

Our codebooks and our API uses the Statistical Data and Metadata eXchange documentation standards to clearly indicate which data is observed, which is missing, which is estimated, and of course, also how it is estimated. This example highlights another important aspect of data trustworthiness. If you have a better idea, you can replace them with a better estimate.

Our indicators come with standardized codebooks that do not only contain the descriptive metadata, but administrative metadata about the history of the indicator values. You will find very important information about the statistical method we used the fill in the data gaps, and even link the reliable, the peer-reviewed scientific, statistical software that made the calculations. For data scientists, we record the plenty of information about the computing environment, too-–this can come handy if your estimates need external authentication, or you suspect a bug.

Avoid the data Sisyphus

If you work in an academic institution, in an NGO or a consultancy, you can never be sure who downloaded the Annual detailed enterprise statistics for services (NACE Rev. 2 H-N and S95) Eurostat folder from Eurostat. Did they modify the dataset? Did they already make corrections with the missing data? What method did they use? To prevent many potential problems, you will likely download it again, and again, and again…

See our The Data Sisyphus blogpost.

We have a better solution. You can always rely on our API to import directly the latest, best data, but if you want to be sure, you can use our regular backups on Zenodo. Zenodo is an open science repository managed by CERN and supported by the European Union. On Zenodo, you can find an authoritative copy of our indicator (and its previous versions) with a digital object identifier, in this case, 10.5281/zenodo.5652118. These datasets will be preserved for decades, and nobody can manipulate them. You cannot accidentally overwrite them, and we have no backdoor access to modify them.

Reprex Joins RECREO Research Consortium To Develop Innovation Indicators

The Scuola Superiore di Studi Universitari e di Perfezionamento Sant’Anna and Università degli Studi di Trento (Italy); University of Glasgow (United Kingdom); Universiteit van Amsterdam and Stichting Europeana from the Netherlands; the National University of Ireland Maynooth (Ireland); Tartu Ulikool (Estonia); Szegedi Tudományegyetem (Hungary); Fundacion Santa Maria La Real del Patrimonio Historico from Spain; the Katholieke Universiteit Leuven, (Belgium); Culture Action Europe AISBL and IDEA Strategische Economische Consulting (Belgium) and Reprex created the REshaping CCSI REsearch: Open data, policy analysis and methods for evidence-based decision-making consortium consortium, which will mainly develop new policy evidence in the field of innovation and inclusiveness for the creative and cultural sectors, industries. The Consortium applies for a Horizon Europe grant with the HORIZON-CL2-2021-HERITAGE-01-03 Cultural and creative industries as a driver of innovation and competitiveness call of the European Commission.

Policymakers face challenges when trying to implement a strict evidence-based approach to decision-making in the field of cultural and creative sectors and industries (CCSI). This is mostly due to four phenomena:

Evidence dissonances in mapping, measuring and analysis of key indicators, which lead to improper generalizations and gaps in decisionmakers’ knowledge and stakeholders’ awareness
Fragmentation of hubs of production and concentration of platforms, which create statistical biases and have features that hardly fit with traditional impact assessment methods;
Datafication, which is revolutionizing CCSI but remains difficult to investigate, thus broadening knowledge gaps; and
Stakeholders’ fragmentation and conflicting interests, which hinders their engagement, awareness-raising and uptake of policy inputs.With its cross-disciplinary consortium of academics, practitioners and a strong network of stakeholders, engaged via participatory research strategies, RECREO will help policymakers and stakeholders tackling such challenges, by generating new knowledge and methods to fill in knowledge and awareness gaps. RECREO will achieve this goal through four actions.

First, it will generate a wide array of horizontal and sector-specific datasets, made openly accessible via the CCSI Data Observatory and the Evidence Synthesis Platform. Second, it will offer an unprecedented EU and comparative mapping and impact assessment of key regulatory and policy measures relevant for CCSI, made available on the Law and Policy Observatory. Third, it will develop innovative methods to measure and assess CCSI innovation, competitiveness and spill-over effects, emphasizing inclusiveness, diversity and sustainability. Last, it will offer policy recommendations and best practices aimed at supporting the sustainable growth and competitiveness of culturally diverse CCSI, and their cross-fertilization with cultural heritage promotion and preservation.
