This is not a scientific study, but we can draw some conclusions that would tend to support the current statistics especially for PV. The one big difference would be the correlation between males and females. We had females returning surveys twice as much as males – 32% males, 68% females for PV. This fact may be due to many factors as the prevailing statistics state that this disease is equal 50/50 between men and women. From the people who have contacted the Foundation throughout the 4.5 years we have been in existence, we calculate that the statistic would be more like 60/40 female to male.
