Because the Romeo figure is a sample, not the entire population. One
normally makes population estimates from samples.

No, it is quite reasonable to state that 55% of the journals sampled
support self-archiving, and to extrapolate from the sample to the
population as a whole. (The only exception would be if there was any
reason to believe the sample was unrepresentative or biassed. But since
the Romeo sample was of the top journals rather than a random sample,
any bias from this is likely to be toward an under-estimate rather
than an over-estimate of the number of journals already formally
supporting self-archiving.)
