Today we used the LOCAL HEALTH website, produced by Local Health England. Some particularly fantastic aspects of this site is that it's free so there is no need to load expensive software and that it integrates Bing or OS open source mapping which enables a clearer view of geographical patterns.
Here's a quick guide on how we used it.
1) Log on to the website.
7) In the detailed report there is a menu where you can select deprivation, population, health-related behaviours etc to really understand the reasons for the geographical variations. There are even graphs comparing this ward to the English average! Happy GIS'ing!
