That's it. It takes nothing else into account (such as the massive "lump" in our population that is baby boomers all beginning to retire) and is therefor a useless statistic. But who cares? Cite whatever statistic that sounds good.
Ya moving to the closest planet to the sun being the first planet to get eaten by our sun when it expands and their is no question that will happen, is a great idea..Not.
The timescale required to move to another planet at our current rate of technological advancement is trivial compared to the length of time that will pass before the sun expands to a diameter that would significantly affect temperatures on the planets in the solar system -- let alone "eat" them.
Even if it took us one hundred thousand years to settle Venus, the sun would have barely changed in that time frame.
