The Atlas of MS is the most extensive worldwide study of the epidemiology of MS and the global availability and accessibility of resources for people with MS.

In September 2008, the MS International Federation and the World Health Organization (WHO) published Atlas: Multiple Sclerosis Resources in the World 2008, and developed the first Atlas of MS website, which enabled users to query the data online.

In 2012/2013 the MS International Federation carried out a second survey in order to update the Atlas, and the 2013 data was added to the 2008 information online.

The main finding from the second survey was that the estimated number of people with MS had increased from 2.1 million in 2008 to 2.3 million in 2013. The global median prevalence used to calculate this figure had increased from 30 (in 2008) to 33 per 100,000 (in 2013). It is not clear if this increase is due to better diagnosis and reporting, or to other causes.

You can use this page to query the 2013 and 2008 data.

Data in the Atlas of MS database for 2013, although the most up-to-date at the time of publication, may sometimes be based on unpublished studies or studies completed between 2008 and 2013. Care should be taken when making direct comparisons between 2008 and 2013 data.

Please check with MSIF's head of international scientific and medical research before publishing direct comparisons between 2008 and 2013 data from the Atlas of MS.
