The article discusses immigration policy in Ireland and the skills of Irish immigrants. The researchers looked at data from the OECD to compare the education levels of Irish immigrants with those in other European countries. They found that Irish immigrants are highly skilled, especially those from EU countries. Some non-EU countries send mainly skilled immigrants, while others send less-skilled workers. The study also explores the impact of EU expansion, the effectiveness of current immigration policies, and how immigration now affects future population trends.
