The Mayors Health Inequalities Strategy sets out his plans to tackle unfair differences in health to make London a healthier, fairer city.
This dataset reports the 14 headline population health indicators that will be used to monitor London’s progress in reducing health inequalities over the next ten years.
The themes of the indicators are listed below. The measures will monitor an identified inequality gap between defined populations.
Healthy life expectancy at birth – male
Healthy life expectancy at birth – female
Children born with low birth weight
School readiness among children
Excess weight in children at age 5-6 (reception) and 10-11 (year 6)
Excess mortality in adults with serious mental illness
Suicide
Mortality caused by Particulate Matter (PM2.5)
Employment
Feeling of belonging to a community (provisional)
HIV late diagnosis
People diagnosed with TB
Adults walking or cycling for two periods of ten minutes each day
Smoking*
Changes in February 2026 update:
* The usual indicator of ‘adults walking or cycling for two periods of ten minutes each day’ metric used is no longer available. This has been replaced with the new metric above for which there is consistent data available from 2015/16 to 2022/23.
** The usual inequality indicator of smoking prevalence in routine/manual workers compared to managerial/professional workers aged 18+ is currently not available. For this reason, this socioeconomic data has been removed from 2020 but may be re-instated at a later date if the data is made available. A replacement indicator on smoking prevalence in routine/manual workers (aged 18-64 years) has been used instead as a comparison with all smokers (aged 18 plus years). However, these metrics are not directly comparable as they cover different age ranges.
