The Environment and Health Atlas for England and Wales

obs-blog-health-atlasThe atlas provides interactive maps of geographical variations for a range of health conditions and environmental agents at a neighbourhood (small-area) scale in England and Wales.

The Environment and Health Atlas for England and Wales is an independent publication produced by the Small Area Health Statistics Unit, an academic unit funded by the Medical Research Council and Public Health England.

Aims

  • To provide baseline information for policy makers and the public on geographic patterns of environmental agents and disease.
  • To help in development of hypotheses to understand and explain variability in disease risk that may relate to the environment, lifestyle factors and/or location.
  • Following on from this, to help in development of research to investigate potential causal relationships between environment and health factors – where either evidence or lack of evidence for an effect provides important information to inform public health and policy.
