Folk notions have often suggested that speaking a different language at home can cause a deficit at school. Recent research suggests the opposite: that early bilingual experience can have cognitive benefits that last throughout adulthood. It was also found that by the third generation, 51% of hispanic families were not speaking Spanish at home.

A public service campaign sought to improve these figures and launched a campaign using the slogan: "Leading with Languages" to try to decrease Spanish speakers who do not speak Spanish due to feeling stigmatized to do so. After the campaign, a poll (of 280 families) found that 48% of hispanic families were not speaking Spanish at home.
