text: **The share of older workers — between 55 and 64 years old — increased significantly, from 11.1%**
  **(2005) to 18.4% (2019).**This corresponds to a growth from 20.1 million to 35.9 million employed persons, 
  or of 79%. 
  The**migrant workforce**in the EU27 also increased in the past two decades. The majority of migrants 
  are intra-EU, that is, all workers who are born in a Member State other than the one where they currently 
  work and reside; this number is estimated at 10.4 million (2019), based on LFS data. Cross-border 
  workers account for another 1.5 million and posted workers for 2.4 million. In 2020, 8.6 million extra-EU 
  citizens (born outside the EU) were employed in the EU labour market, out of 196 million persons aged 
  from 20 to 64 years, corresponding to 4.4% of the total. The sum of all different categories of mobile 
  extra- and intra-EU workers is roughly 23 million, or about 12% of the EU workforce.
