75,000 EU Nationals convicted of committing crimes in the UK
about 1.8 percent of all EU nationals in the UK
75,000 refers to an "historical backlog" of notifications not sent to European law enforcement agencies" and only appears to cover a 5 year period (after 2012); "The police national computer (PNC) error went undetected for five years."^
11 million people in the UK have criminal records,
including an astonishing 30% of all men by the age of 30
Although the research was carried out "on men born in 1953"
So less likely to commit crimes than UK nationals?
Apparently not - from the same organisation as the pp's link:
"Significant numbers of EUSS applicants will have a criminal record."
"Over 11 million people in the UK - around 1 in 6 adults - have a criminal record, and we have no reason to believe that the proportion of EU nationals with a criminal record is significantly different to this. Based on 3.3 million EU nationals, this equates to 550,000 with a criminal record."
"A Migration Advisory Committee report showed that of all the cautions/convictions that were given from 2012-2016, 88.5 per cent were given to UK/Ireland citizens, 6.7 per cent to EEA citizens and 4.7 per cent given to non-EEA citizens."
"It goes on to highlight how “EEA citizens (and in particular New Member States) are more likely to receive a caution/conviction than their share of the population would suggest although highlights caution in interpreting this.This means potentially hundreds of thousands of people with a criminal record will need to apply for settled status."
"A large number of EU nationals deported have a criminal record. Home Office statistics report the number of what they refer to as ‘foreign national offenders’ (FNOs) returned from the UK each year. In the 5 years 2014-2018, 18,050 EU nationals were deported who had been convicted in the UK or abroad.This represents 63% of all FNOs deported. In 2018 alone, 3,670 EU nationals were deported, representing more than two-thirds (68%) of all ‘foreign national offenders’ deported."
"The majority of those deported had served a prison sentence. In the 5 years 2014-2018, 15,303 EU nationals had been deported from the UK having served prison sentences. This represents 85% of the 18,050 deported."
