One thing I would look at is the age distribution of the population as a whole.



The US is getting older, while there is a very pronounced "youth bulge" in much of the third world.

Another factor to consider is the number of <50 respondents. A reasonable assumption (that would have to be tested of course), is that most respondents in this particular forum would be the ones it is aimed at, i.e. 50 plusers. The 50-54 demographic in BF may consist of a fair amount in that age group who are putting off admitting to it, therefore, not visiting 50+ until they are ready to own up to it.
