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.
Canvas
Start Year = 2019, Cost of Space Stuff- $10000/kg, Total Space Stuff-31.6 kilotonnes
Ending Year- 2219, GWP- 7.9, SE- 261.8, Total- 269.7 Quadrillion, SE is 97.05%
Cost of Space Stuff- $3.47/kg with habitats for 75.5 billion peeps
7.6 billion grows to 45.6 billion at .9%/yr with very few births and fewer deaths
