Since this is during the Gold Rush in California, population estimates are also very hard to get right and had to do a lot of reading and look through a lot of sources to get California's towns as accurate possible, so please bare with me if there's any errors in respect to this region.
As for Utah Territory, no estimates for localities were given and only populations for counties were given, but luckily I was able to find an estimate for Salt Lake City calculated through the amount of households in the region.
