Key statistics and data collected from MSIF's Atlas of MS

The latest edition of the Atlas of MS shows there are 2.9 million people living with multiple sclerosis around the world.

The Atlas of MS is a powerful advocacy tool for MS organisations and advocates to drive policy changes that can remove obstacles for people with MS and their families in their country. The data is a key way of shining a spotlight on MS to increase awareness and understanding around the world.

Who is affected?

Who is affected?


years is the global average age of an MS diagnosis. Data is not available on the age of diagnosis for this country.

Women with MS


of people with MS are women.

Number of people with MS?

Number of people with MS


people are living with MS. This equates to 1 in every 700 people.

Children with MS


children under the age of 18 are
living with MS.

Diagnosis of MS?

Diagnosis of MS


new people are diagnosed each year. That's 333 diagnosed every month.

Diagnosed with MS


of people are initially diagnosed with relapsing-remitting MS. 15% have progressive MS.

MS neurologists

MS neurologists


neurologists who specialise in MS. This means there is 1 MS neurologist for every 333 people with MS

MS nurses

MS nurses


nurses who specialise in MS across the globe. This means globally there is 1 MS nurse for every 416 people with MS. There is no data for the number of nurses who specialise in MS for the country.

Note that whilst MS neurologists and MS nurses specialise in the care of people with MS, they are also likely to support people with other neurological conditions, which is not captured in our data.

Disease modifying therapies used to treat MS

In the Atlas of MS we categorise on-label DMTs into three classes: moderate efficacy, good efficacy and high efficacy. Countries should aim to have access to a range of DMTs so that people with MS have options to suit their disease course and individual circumstances.

On-label DMTs used by efficacy category

High efficacy

Good efficacy

Moderate efficacy

Cladribine (oral)
Dimethyl fumarate
Diroximel fumarate
Monomethyl fumarate
Glatiramer acetate
Interferon-beta 1a
Interferon-beta 1b
Peginterferon-beta 1a

Off-label DMTs used

DMTs that have been licensed specifically for MS are referred to as 'on-label'. Please note on and off-label here refers to the regulatory status in the majority of countries.

What is the Atlas of MS?

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

2020-22 worldwide study

The data shows that the number of people with MS across the globe has increased from 2.3 million in 2013 to 2.8 million in 2020 and 2.9 in 2023. It highlights the many barriers and inequalities that people with MS face in accessing diagnosis, treatment and care.

Powerful tool for change

The information in the Atlas of MS can be a powerful advocacy tool, shining a spotlight on MS and raising awareness of the lack of adequate resources available to diagnose, inform, treat, rehabilitate and support people with MS worldwide.

Worldwide collaboration

The Atlas of MS relies on data supplied by MS organisations from around the world. We are most grateful to the country coordinators and their colleagues for taking the time and effort to gather the information and data.

This 3rd edition of the Atlas of MS shines a spotlight on the barriers to accessing diagnosis and disease modifying therapies around the world. These issues are particularly evident in low and middle income countries but high income countries are not exempt. This report highlights the need for major policy changes to ensure early diagnosis and improved access to a range of treatments, to guarantee the best possible outcomes for people with MS. Information from the Atlas of MS should be used to guide policy-makers, health planners and specialists, in order to close the gaps in care, decrease inequities globally and provide a better future for people with MS and their families.
