- The average effect of immigrant concentration on students’ educational outcome is negative and significant.
- The average peer group effect is relatively weak in magnitude, which is due to a weak negative marginal effect of immigrant concentration on student educational outcome, until the immigrant concentration exceeds 50 percent
- The effect of immigrant concentration on educational outcome is almost twice as large for immigrant students as for native Danish students, confirming the existence of asymmetric peer effects.
- There is a tipping point at which school percentage of immigrants significantly affects educational outcomes, at around 50% immigrant concentration.
