The 2015 City RepTrak study surveyed more than 19,000 residents of G8 countries -- France, Germany, Italy, UK, Japan, U.S., Canada and Russia.

Respondents were asked to rate the world's 101 best cities based on their levels of trust, esteem, admiration and respect.

"We see linkages with other research when we compare our reputation rankings to data like tourism and investment," said Fernando Prado, managing partner at the Reputation Institute.

"The measures end up being strongly correlated."

For a city, a strong reputation is closely linked to a desire by individuals to visit, live, work or invest there, he said.

"This is a bottom-line issue for local policymakers," added Prado.

"Cities with a good reputation welcome more tourists, host relevant events and attract more investment and talent."
