The "Blue Card" is EU-level scheme
allowing high-skilled non-EU citizens to work and live in any country within the European Union, excluding Denmark, Ireland and the United Kingdom,
According to a 2016 EU press release it didn't work too well, so it was reformed then:
The EU Blue Card scheme, adopted in 2009, has proven insufficient and unattractive so far and is therefore underused. Restrictive admission conditions and the existence of parallel rules, conditions and procedures at national level have limited the use of the EU scheme. Only 31% of highly-educated migrants to OECD countries chose the EU as a destination, meaning skilled workers are choosing other destinations which compete economically with the EU.
Today's proposal revamps the existing rules and aims to improve the EU’s ability to attract and retain highly skilled third-country nationals [...]
But neither source gives any actual numbers for how many of these Blue Cards have been issued (either before or after the reform). So are there any yearly stats of how many such cards have been granted? (It would be even better if the stats were also broken by country.)
