From Fair Vote:

A record 23 cities in Utah passed ranked choice voting ordinances for elections in 2021, more than doubling the number of elections that will allow voters to rank mayoral candidates. Altogether, with these added cities, 53 jurisdictions are projected to use RCV in upcoming elections. The 23 Utah cities, which includes Salt Lake City (population 200,000), each voted to adopt ranked choice voting specifically for municipal elections in the fall of 2021. Those cities will vote each year to continue using ranked choice voting. 

Coincidentally, I had recently flagged here a piece on why conservatism in Utah is different from that in many other states.
