Just increasing lifespans alone would have lots of effects, but they wouldn't be happening in a vacuum. Once we have that type of technology, there's going to be other variables at play. For instance, I think we'll see close to 100% technological unemployment before we can extend human lifespans by 200 years. In that type of environment, most humans would be effectively retired. Even if we have less than 100% technological unemployment, birth rates are generally declining, so there's lots of ways that could interact with increased longevity. EDIT: fixed mispelling
