I know the PM resides at 10 Downing Street, but the article just states that he got to "stay Number 10". Is this just some weird imperial grammar rule?
I haven't bother reading the linked article, but did they bother taking residency status into account? Many more Latinos than Asians are here illegally, especially in southern CA. You have to imagine kids that live under constant fear of deportation are less likely to care about doing well in school.
