For the 18th year in a row, American adults believe nurses are the most honest workers, according to a Gallup poll.

The results show that 85% of US adults believe that nurses are honest or very honest, putting them above 21 other jobs like police officers, doctors, teachers and businesspeople.

Second on the list are engineers, with 66% of people saying that engineers are honest or very honest. Also in the top five are doctors, who received a score of 65%, and pharmacists, at 64%. The fifth highest score was for dentists, at 61%.

Police officers are in the middle of the list: only 54% of Americans feel they can trust the police to be honest.

People in the government are among the least trusted by Americans. Members of the US Senate are only trusted by 13% of the adults who took the poll. Members of both the Senate and the House of Representatives together only got 12%.

The lowest on the list are people who sell cars, at 9%.

The high number for nurses hasn't changed much over the years. In 2018, the number was 84%. In 2017, it was 82%, dropping 2 points from their 2016 score of 84%.

The poll was done at the beginning of December 2019. Gallup spoke to 1,025 adults in all 50 US states and Washington, DC.
