Sir Mark acknowledged that some Londoners would still not feel the city was a safe place to live and suggested social media content, in “ever more angry, polarised, partisan times” played a part.
“The truth is ever less present and it’s more about opinion or mischief. That’s why using something as objective as this is one important way to say, ‘OK, London is relatively safe.'”
Sir Sadiq said many people had “been trying to talk London down”.
“Whether it’s President Donald Trump, whether it’s politicians concentrated in Europe, this country, or other parts of the world, I can understand why they hate London,” the mayor said.
“We are diverse, we are progressive, we are liberal, we are successful, but even the harshest critics of London would have to accept these figures are remarkable.”
There has been a long-running spat between Sir Sadiq and US President Trump, who last year accused the mayor of doing a “terrible job” and said “crime in London is through the roof”.
The commissioner and the mayor are also under pressure to improve confidence in policing following a series of scandals.
Last week, an internal Met Police review, which examined a 10-year period up to the end of March 2023, revealed 131 officers and staff committed crimes or misconduct after they were not properly vetted.
One officer, Cliff Mitchell, was allowed to join the force in 2020 after a vetting panel, partly aimed at improving diversity, overturned a decision to reject him despite a previous child rape allegation.
