Sending them to space is totally not a viable means to compensate for population growth on Earth. The cost for each person is so astronomically high we couldn't afford to send more than a handful of people. The way to get population under control on any planet is to get people to have less kids.
And for the same reason, the only viable way to grow a population on a colony past a bare minimum is to get them to have more kids.
