His book The Death of the West expressed concern at the declining numbers of non-Hispanic whites in America, arguing that few nations have ever held together without an ethnic majority. In a 2002 speech, he said, "In the next 50 years, the Third World will grow by the equivalent of 30 to 40 new Mexicos. If you go to the end of the century, the white and European population is down to about three percent. This is what I call the death of the West. I see the nations dying when the populations die. I see the civilization dying. It is under attack in our own countries, from our own people." Buchanan believes that if these demographic trends continue, young Americans will spend their golden years in a "third world America", which will reduce the nation to a conglomeration of peoples with nothing in common. He believes this can be credited to the 1965 Immigration Act and the cultural revolution of the 1960s. He also notes that past immigration was European, while 90 percent of new legal immigrants are Asian, African, and Latin American and that they are not "melting and reforming".
