^U.S. Census Bureau, Statistical Abstract of the United States: 2003, Section 1 Population(pdf). U.S. Census Bureau: 59 pages （英语）. Table 47 gives the figure of 214,809,000 for those five years old and over who speak exclusively English at home. Based on the American Community Survey, these results exclude those living communally (such as college dormitories, institutions, and group homes), and by definition exclude native English speakers who speak more than one language at home.
^Languages spoken, 2006 Census, Statistics New Zealand. No figure is given for the number of native speakers, but it would be somewhere between the number of people who spoke English only (3,008,058) and the total number of English speakers (3,673,623), if one ignores the 197,187 people who did not provide a usable answer.
