A natural experiment of the Western Extension to the London Congestion Zone
Project aims
This project will use data on air pollution concentrations and hospital admissions between 2003 and 2014. Air pollution data (nitrogen dioxide and particulate matter) will be linked to residential addresses. This will allow us to examine exposure to air pollution before, during and after the implementation of the Western Extension Zone. We will assess all hospital admissions, and admissions for all respiratory and all cardiovascular diseases separately. These will be combined with population data to examine hospitalisation rates. We will have one intervention group of the residents compared with two other groups: one from just outside the area and another similar in terms of deprivation.
