[Star Wars] What percentage of people have been off planet?

Did most people stay on the planet they were born on for their entire lives? How accessible was transport to a different planet? This likely depends on the planet and its relative wealth, similar to differences in how many people have left their home country at some point in the real world, either for work or vacation, based on their wealth and demographics.

People seem to move planet much more often and easily than moving elsewhere on their own planet. I'd say it's about the proportion of people who travel to different countries for work or fun from our universe.

We see in Andor that tourism exists as does interplanetary trade on an individual level. It's not all freight pilots moving shit around, sometimes people go places to get stuff.

I'd say it's probably about as hard and common to leave the planet as it is for your garden variety American to leave the US.
