A November 2009 online Harris poll of 2,303 adult Americans (18 and older)[63] showed a slight increase in belief in a personal God (82%) over previous polls conducted in 2008 and 2005. The poll also showed increases in religiously associated supernatural beliefs and stable of declining beliefs in non-religiously associated supernatural beliefs.
A late 2008 online Harris poll of 2,126 U.S. adults (18 and older)[64] found that "80% of adult Americans believe in God - unchanged since the last time we asked the question in 2005," but that beliefs in the supernatural showed a slight increase over the same period.
A 2006 CBS News Poll of 899 U.S. adults found that 82% of those surveyed believed in God, while 9% believed in "some other universal spirit or higher power", 8% believed in neither, and 1% were unsure.[citation needed]
A 2005 online Harris Poll of 2,010 U.S. adults (18 and older)[65] found that 73% of those surveyed said that they believed in a God, 11% said they believed there was no God, and 16% said that they were not sure whether or not there was a God. The believers in God included 58% of respondents who said they were "absolutely certain", and 15% who said they were "somewhat certain" that there is a God. The believers in no God included 6% who were "absolutely certain", and 6% who were "somewhat certain" that there is no God. About 29% believed that God "controls what happens on Earth", while a plurality (44%) believed that God "observes but does not control what happens on Earth". The poll also showed that an "absolute certain" belief in God is correlated to age: only 43%-45% of those aged 1829 were "absolutely certain" that God exists, while 54% of those aged 3039 were "absolutely certain" that God exists, and 63%-65% of those aged 40 and older were "absolutely certain" that God exists.
