Nurses and pharmacists were considered to have the highest standards, according to the Gallup poll.
Only 10 per cent of respondents rated members of Congress very highly or highly for their integrity, while 54 per cent scored them "very low or low."
At the bottom of the barrel were the car salespeople — only eight per cent thought very highly of them, while advertising people did not do much better — just 11 per cent of those surveyed rated them very highly.
Nurses however were on the top of the list — 85 per cent of people gave them a very high or high mark for honesty and strong ethical values.
Pharmacists (75 per cent), doctors and engineers (both 70), police officers (58), college teachers (53), and clergy (52) were the only other occupations to score above 50 per cent when it came to being given a very high or high rating.
There was little joy for bankers (28 per cent) and journalists (24), though both did better than business executives (21), state governors (20), lawyers (19), and insurance salesmen (15), when it came to top marks.
Some 45 per cent of those surveyed had a very low or low rating of senators, with just 14 per cent viewing their integrity as being very high or high.
Gallup noted that members of the US House of Representatives have never done well in the 36 year history of the honesty and ethical standards survey.
The highest honesty rating for these lawmakers came in November 2001, two months after the 9/11 attacks, when 25 percent of Americans ranked them highly.
Gallup said its November 26-29 poll of 1,015 adults has a plus or minus four percentage point margin or error. — AFP-Relaxnews
