Hi crystal4290,
The MS geographical distribution is very complex, with great
variations not only between countries, but within countries as well. I
hope you find the data that I've been able to gather together suitable
to your needs.
>>>>>>>>>>Intro
The MS Information Sourcebook:
"Epidemiology is the study of disease patterns that takes into account
variations in geography, demographics, socioeconomic status, genetics,
and infectious causes. Epidemiologists contribute to knowledge about
MS by studying the relationships between these factors, as well as
patterns of migration, that may be related to areas with high or low
rates of MS. Epidemiological studies can help to identify factors
that may be related to the risk of developing MS. These factors can
then be studied in greater detail as possible clues to the cause(s) of
MS."
http://www.nationalmssociety.org/Sourcebook-Epidemiology.asp
A 2002 study estimated that approximately 211,000 Americans suffer
from MS. Older studies suggest that it affects about 1.1 million
people worldwide. The incidence appears to be increasing in women.
Geography.
"The risk for MS is higher in different regions of the world. In
general, MS is more prevalent in temperate regions than in the
tropics. Specifically, prevalence is highest in northern and central
Europe (except northern Scandinavia), Italy, southern Australia, and
northern regions of North America. Middle-risk areas are southern
Europe (except Italy), southern US, northern Australia, northern
Scandinavia, the Caucasian sections of South Africa, and maybe Central
America. Low-risk areas include parts of Africa and Asia, the
Caribbean, Mexico, and possibly northern South America It is unclear
whether this pattern is attributable to environmental factors,
genetics, or both."

"Much of the data in the following table is based on estimates by
national MS Societies and others and extrapolations of survey data for
regions within the countries"

UNITED STATES 2001
It is estimated that 10,400 people are diagnosed with MS on a yearly
basis, broken down to 200 new instances per week.

Prevalence map of MS (cases/100,000) in the USA:
http://www.jr2.ox.ac.uk/bandolier/booth/neurol/MSgeog.html
"In the U.S., MS occurs more frequently in states that are above the
37th parallel than in states below it. From east to west, the 37th
parallel extends from Newport News, VA, to Santa Cruz, CA-running
along the northern border of North Carolina to the northern border of
Arizona and including most of California. The MS prevalence rate for
the region below the 37th parallel is 57 to 78 cases per 100,000
people. The prevalence rate for those above the 37th parallel is 110
to 140 cases per 100,000 people. Nationwide, there are an estimated
250,000 to 350,000 people with MS."
