Reply #53: No, let's say "1 in 12", since that's what the CDC says

when used with the midpoint '5 to 7%' self-identified MSM that the CDC also quotes. You could say under 10%, since that's the upper limit of the CDC estimate.

Yes, it's much higher than the figure for some other groups; but that's not what this thread is about. The 5 city figures are not "adjust(ed) using the best demographic and statistical models"; they are weighted towards Baltimore (and, for that matter, more towards the 30-39 age group than the 40-49 one, and away from the 50+ group), and are just simple totals of whom they tested, so the 46% prevalence among blacks is not a proper statistic for any population, urban or not.

The 'adjusted' figure is about 600,000 total MSM with HIV, diagnosed and undiagnosed, in the USA.
