„Parents with low socio-economic status spend less time, on average, on developmental activities with their children, which is a key driver of the transmission of inequalities. On average across OECD countries, the percentage of children from an advantaged socio-economic background who are regularly exposed to early literacy and numeracy activities is 22 percentage points higher than for children from a disadvantaged socio-economic background.“
