Family income effects on mathematics achievement: their relative magnitude and causal pathways

Abstract

This study examines the influence of family income on student achievement in mathematics utilising data from the parents’ questionnaire for nine countries participating in the OECD’s 2012 PISA study. It finds non-trivial effects for family income that were consistently larger than, or comparable to, the effects of more commonly used measures of socio-economic background: parents’ education and occupational status.
