Some insights in the most popular Open Data categories
Facts and practical examples
The European Data Portal harvests the metadata of Public Sector Information available on portals, both national, regional and local, throughout Europe. Currently there are 71 catalogues which are harvested, with a total amount of over 616k datasets available on the European Data Portal. These datasets are divided over 13 data categories. Data categories are categorisations of datasets linked to a common theme. The 13 data categories available on the European Data Portal match with the categories identified by the European Commission in the context of the revision of the European .
But what are the most popular data categories? When looking at the availability of datasets on the European Data Portal per category, it can be noticed that the category (>117k datasets) and (>112k) have the most available datasets. They are followed by the category , offering over 81k datasets. On the contrary, categories such as , and include less than 10k datasets. This shows that substantial differences exist in the data available per catalogue. This might be clarified by countries prioritising the release of certain data categories above others, for example those with a high potential for re-use by organisations. Another explanation would be that there is just more data available in certain categories, for example because of a strong organisational push in those fields.

When we look at the most popular categories in terms of page views on the European Data portal, Regions & Cities and Transport are the most popular data category with the highest number of page views. The data categories, Regions & Cities, Transport and Agriculture, Fisheries, Forestry and Food together represent 39% of the page views on the European Data Portal. But what kind of data can typically be found in these domains?
Examples of datasets in the Transport domain include , information on and . An example of a dataset in the Regions & Cities category is a on land use plans in the Italian Province of Südtirol. The map below shows the borders of zoning plans in the area of Bolzano.
