If I posted everything my coworkers and I share on our #industryintel Slack channel you'd kick me out of here...but...I found this article particularly interesting in putting context on the space industry (and ostensibly, SpaceX).
The Space Review: Charting a path for the space industry’s growth
Supporting that article, while I don't think the latest Bryce report is public domain you can find their charts for 2016 (the numbers are more or less similar to 2018, minus the growth referred to in the above article). There's some good detail on the breakdown of the total space economy which hasn't change much proportionally into 2018. Most interesting are slides 4 and 7.
