	Overeducation	Educational Match	Undereducation	Overskilling	Skill Match	Underskilling
\(\sigma _{u0j}^2\)	0.971 (0.292)	0.575 (0.172)	1.02 (0.366)	0.295 (0.093)	0.196 (0.063)	0.016 (0.017)
ICC	0.228	0.148	0.236	0.08 2	0.056	0.005
N_i	14,266	14,266	14,266	14,266	14,266	14,266
N_j	25	25	25	25	25	25

ICC = Fraction of total variance in each mismatching category that is due to occupation-level variance (\(\sigma _{u0j}^2\) with s.e. in parentheses)
Sample excludes workers aged 15–24 and 65 + and workers without a vocational degree (for detailed sample definition see Sect. 3.1)
