GWP is gross world product and SE is the space sector of the economy. GWP grows 2.3% per year to increase by an order of magnitude every century, and the space sector grows at 7%, since it's currently been chugging along at between 6 and 8 percent for the last decade. SE becomes a dominant sector in the early 22nd here, which is hopeful but represents my bias... I do expect explosive growth, way above the world economy as we develop the resources of the solar system, especially space based solar power.
