First, all the countries in the Schengen treaty I think end up with the same score. Indeed France, Germany and Italy do. I would imagine many more do too (e.g. Spain). It seemed like it would have been a better label.
On the other hand I am surprised that Denmark got more.. .and it is kind of a counterexample to my first point. Isn't Denmark in the Schengen treaty too? Where else can they go than Germany/French/Italians can't?
No. The Schengen treaty affects (maybe not that strictly) visa policies for the member states in the way that all the members are expected to have the same visa requirements (that's quite logical).
There are only some old EU15 members listed, but not a single country from the 2004 extension, nor Bulgaria and Romania. I live in the Czech republic, which has some kind of non-visa agreement with the USA (ESTA?), something much simpler and easier than regular visas, but you still need some kind of stamp. In fact, there was a discussion about this and how should be our EU membership leveraged in order to get a better position, but there weren't much of a agreement. I believe that old EU states (Great Britain first) weren't happy about the fact that there should be some common policy.
(Indeed, Schengen isn't equal to EU, it isn't even a subset of it, there are non-EU countries included, and some EU states aren't members (Great Britain). But there isn't any common policy, both EU and schengen-wide.)
I don't think there's anything stopping Schengen countries negotiating better travel conditions for their citizens. It's the Visa situation for travelling to visit the entire Schengen area that's homogenised. Working visas etc. are yet another matter.
It's a measurement of how likely it is that a citizen in a country want to become an illegal immigrant elsewhere. The small, "nice", western european welfare states have always scored very high on this for a long time.
Denmark is a member of Schengen, but we also have deals with Sweden and Norway that doesn't even require passports to get there, and I don't imagine I would need a passport to go visit Iceland either.
