Fig. 1: Norwegian municipalities, coloured by average values of variables for students in our analytic sample (a = achievement; b = family income; c = student EA-PGI).

From: A population-wide gene-environment interaction study on how genes, schools, and residential areas shape achievement

Notes: We aggregated to the broader municipality level due to the anonymity of the school and neighbourhood identifiers. Maps are based on grade 5 variables and residential identifiers. Grey= no participants resided in that municipality. Some municipalities are more sparsely populated, such that the depth of colour only reflects one or two participants. This does not hold for school-level family income (1B), which was based on the average income of all parents of peers attending participants’ schools, not only other study participants’ parents.
