Challenges in assembling data from all EU member states on their foreign prison population for the Eurocrimes feature

Around 11,500 Romanians are in prison in the EU, compared to 28,000 at home - Jilava prison near Bucharest
 
 
An international team of journalists has made an estimate on the numbers of foriegn nationals in jail in EU prisons.
 
This is based on our own requests made to official bodies in every member state and the replies that we have received.

However each institution has its own method of compiling figures - as there is no agreed upon standard for drawing up lists of foreign prisoners across the EU.

Therefore our estimate is based on the closest possible approximation to a true figure that could be assembled from this information.

The real number could be higher or lower.

We would also like to stress that this is not a scientific or an academic exercise, nor is this a professional statistical inquiry. The writers are all professional journalists and all have experience writing on crime and prisons.

Therefore this is a work in progress, and in no way can be seen a definitive picture. We would invite discussion and dialogue on this issue, and contributions from all the official parties and watchdogs to see how we and statistics bodies can best assemble these numbers.

 

Issues in compiling data

A major challenge in compiling lists of foreign prisoners (and by prisoners we mean those in custody - which includes detainees and convicted criminals), is that the figures are constantly changing throughout the year.

We asked every member state to give us the prisoner population for the date 31 December for the years 2015, 2014 and 2013.

But not all could give the figures for this date. Also in the case of three countries (Belgium, Denmark, Netherlands), they were aware of the discrepancies in trying to make a true assessment of the situation by picking a single date, so decided to compile the data using the average figure for the year.

This is arguably a more accurate picture of the true situation, but not one rolled out across all EU member states.

Other countries gave us the data for the entire year, which will mean there is a margin of error in the final figures.

Some could not give the figures for both those in custody and those convicted with final sentences.

Therefore these figures are not consistent in their methodology of collection.

Despite these margins of error, we have several central claims that cannot be refuted. These are that the largest foreign prison populations in the EU, by a large distance, are Morocco and Romania. We can also state that the largest number of criminals in an EU country as a percentage of its expat population belongs to Lithuania.
