Here's a text list of all Jove Observatory locations.
Pochven technically has four Jove Observatories, but those systems do not spawn Drifter wormholes so I list it as having 0.
Here's a Google Sheet of all the data used to build this. If you want to play with it, File → Make a copy.
Note: the 200 Abyssal Deadspace and "No Name" systems are excluded & the 5 Drifter system J numbers are changed to their new proper names.
This data can be directly sourced via ESI or the SDE, which Steve Ronuken helpfully repackages (you probably don't wanna futz w/YAML).

69
KSKnown Space systems are part of the stargate network (I include Pochven since it has gates, but it's only accessible via wormholes or filaments).
regions (66 accessible). 790 constellations (755 accessible). 5,405 systems (5,202 accessible).
HS: 1,193
LS:687
NS: 3,525 (3,295 accessible, includes Zarzakh).

2,604
JSJ-Space systems are only accessible via wormholes. The vast majority of which begin with the letter J. I include Thera and the five named Drifter systems.
systems in 12 classes, all accessible, for 8,036 total systems of all types, 7,806 accessible (excluding Abyssal Deadspace & "No Name" systems).
Here's a table of how many different hole types each class/security of space spawns.
For specific Asset Safety system associations, check out calavoow's tool. I also made DOTLAN maps of all asset safety systems.
Regarding the wormhole percentages: you can visually determine exactly which region any K-Space wormhole leads to. I just thought the stats were interesting.
Average region name length: 8.3, min: 4 (2), max: 20 (1).
Average system name length: 6.4, min: 3 (44), max: 18 (2).
Total stargates: 13,774.
Average gates per region (ignoring those with 0): 205.6.
Average gates per system (ignoring those with 0): 2.6, min: 3 (44), max: 8 (2).
Average pipes per region: 28.2.
Average deadends per region: 10.9.
