The 2013 World Atlas of MS has been published by MS International Foundation and is available here. The key findings are:
- The estimated number of people with MS has increased from 2.1 million in 2008 to 2.3 million in 2013
- The 2:1 ratio of women to men with MS has not changed significantly since 2008
- Substantial global inequalities remain in terms of access to treatment and medical care
You can do your own investigation of MS trends at www.atlasofms.org, where additional data is available from both 2008 and 2013, allowing side-by-side comparisons.
