Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what information his Department holds on differential impacts (a) geographically and (b) by socioeconomic group of poor (i) outdoor and (ii) indoor air quality.

The UK Health Security Agency (UKHSA) produces annual estimates of the fraction of mortality attributable to particulate air pollution (outdoor air quality) within the Public Health Outcomes Framework for England. The indicator values are estimated at different geographical levels including local authorities and regions, and at different deprivation deciles. UKHSA does not hold information on differential geographical and socioeconomic impacts of indoor air quality.
