The Census 2000 numbers show that the country is presently 69% non-hispanic white. However, this figure includes millions of non-Europeans (North Africans, Middle Easterners et al) bringing down the European derived American population to around 64-65%. I don't have the exact numbers but I would estimate that almost half of the children born in the country are not exclusively European (the percentage of interracial marriages is also increasing ). What this means is that no change in our immigration policy is going to change the fact that people with a exclusively European heritage are going to become a minority in this country.
