I think most of these estimated are pretty spot on, but I hope SLC's number is seriously under estimated. With nearly 2 million extra residents along the Wasatch Front, SLC is only estimated to have 233,000 people. Demographics are changing across the country and millennials are preferring downtown and urban centers in large numbers and if future generations continue the trend I think SLC will see more than 40,000 new residents over the next 36 years. The report indicates the need for more centralized development, but I think there are undervaluing SLC. Imagine a state with nearly 6 million people whose largest city is just over 200,000? I just hope that these estimates are wrong and that SLC is a lot more urban in 2050 than this report suggests.

I don't see much of the growth happening in Eagle Mountain and the Saratoga Springs without a full fledged limited access highway going through Eagle Mountain and connecting to the I-15 south of Utah Lake.
Without the highway, traffic and travel time is going to stop any further growth from happening in only the next few years, let alone 36 years.
I also think water is a resource that is going to limit expansion and growth in areas such as Eagle Mountain and Tooele County. It was only a few years ago that reports came out that Tooele County was nearly at its maximum water share and it would only be able to grow by maybe 15% to 20% total without needing to secure more water rights.
I don't know how much water rights Eagle Mountain has or even Saratoga Springs but I doubt it is enough to support the populations listed.
As for SLC population numbers, I think if the population counts for the state are correct and we factor in commute times, traffic and water issues. I think at least 2/3 of the population numbers for Tooele County would be added to Salt Lake County and Davis County. Then 2/3 of increase for Saratoga Springs and Eagle Mountain would be added to be split with 60% to the urban corridor in Utah County (Lehi, Alpine, AF, Orem, Provo, etc.) and 40% being in SL County and possibly Davis County depending on employment locations.
The downside is that it would drop the growth in Utah County and Tooele County downward accordingly but also increase SL County and Davis County populations.
36 years is really hard to project outwards on because they are using growth rates from the past to justify them going forward and that can't be the case because of the factors stated previously.
I do think that Salt Lake City will see growth and I would expect it to be at least 40,000 in the next 36 years. With the shift in demographics, and the return to Urban Living that is occurring, I wouldn't be surprise to see it increase by 60,000 in the next 36 years.
Now of course, this could all be moot as an HQ relocation to SLC, oil and gas costs dramatically increase or a large earthquake happens in California and people relocate en mass, or Utah could enact green belts. In any of these situations we could see a dramatic change to city populations in SL, Davis, Weber and Utah Counties. If it happened sooner, it would be along existing transit lines which would reduce the projected growth in other areas as well as expedite transit expansion.
Or again, Yellowstone could have a mega eruption and we could be in no mans land for 100+ years or so.
I think that a 5 to 10 year projection is in the safe range when projecting actual populations in cities and municipalities. 10+ year projects are okay for general population counts for Counties and State. Anything beyond 20 years should never list city population estimates as there are too many factors that could change them that aren't known now.
