Black, Asian and minority ethnic Londoners have been hardest hit by rising living costs in the capital, according to a new study.
Research by the Labour Party also found that parents, low income workers and people with disabilities are among the worst affected.
Assembly Member Jennette Arnold called for a scheme to monitor data on inequalities across employment, education, criminal justice and health.
She said: "Despite being one of the wealthiest cities in the world, the most vulnerable people in London are falling further behind the rest.
"It's unacceptable that vulnerable Londoners are bearing the brunt of the policies of the mayor and the Government."
