Students IQ scores increase significantly as the level of reported parental income increases

Additionally, higher-income families may also have greater access to healthcare and nutrition, which can impact cognitive development. However, it is important to note that IQ scores are not solely determined by genetics or socioeconomic status, and individual differences in intelligence can still exist within every income level.
