Notes:
With this data, we can estimate the number of people who will have SRS at some point in their life.
(Remember, SRS is a once-in-a-lifetime event for a transsexual.)
The ratio of people who have a condition, compared to the larger population, is called the Prevalence.
Thus, the Prevalence of lifetime SRS means that 1 in how many people (who live in the US) have had or will have SRS at some time in their life?
This is based on our count of 1230 surgeries per year on US residents.
For the answer, go on to the next slide.
