Low Birth Weight

A map that shows the population estimates (percentage) of births under 2.5kg by ward in Bolton.

The Environment and Health Atlas for England and Wales is an independent publication produced by the Small Area Health Statistics Unit (SAHSU), an academic unit funded by the Medical Research Council and Public Health England. The aims of the atlas are:

  • 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.

The atlas provides maps of the geographical variations for a range of health conditions and environmental agents at a small-area scale (census wards). The maps have been developed as a resource for those working in public health and public health policy and for the general public to better understand the geographic distribution of environmental factors and disease.

This is the Low Birthweight Babies (<2,500 grams) JSNA Indicator Sheet (updated May 2015) from the Child and Maternal Health section. JSNA Indicator Sheets summarise the current position and recent trends for Bolton, comparators to Bolton, and inequalities across population groups and geographical areas of Bolton.


  • Bolton has a greater proportion of low birthweight births than is average for both England and the North West region;
  • Overall, the proportion of low birthweight births in Bolton has reduced over recent years but has increased for the latest period;
  • Bolton currently has the second highest rate of low birthweight births for its statistical peer group;
  • There are inequalities by deprivation group for low birthweight births, and whilst Bolton's current level of inequality is not statistically significantly higher than the England median inequality, it is very close to being so.
