I view users by city using this SQL query:

    ROW_NUMBER() OVER(ORDER BY Reputation DESC) AS [#], 
    Id AS [User Link], 
 LOWER(Location) LIKE 'sulaimani, iraq' or LOWER(Location) LIKE 'erbil, iraq'
    Reputation DESC;

This works.

I don't like the repetition of the LIKE clause - this could get unwieldy if I want to include many more locations (but not the whole country).

    \$\begingroup\$ Does SEDE not support LOWER(Location) IN ('sulaimani, iraq', 'erbil, iraq')? That would be a little bit more manageable. I think that the Location value is free-form anyway, so could be difficult unless users are consistent and don't make spelling errors! \$\endgroup\$ Aug 28 at 11:48
 LOWER(Location) LIKE 'sulaimani, iraq' or LOWER(Location) LIKE 'erbil, iraq'

It is not necessary to use LIKE if you want an exact match. The = is sufficient in that case.

 LOWER(Location) = 'sulaimani, iraq' or LOWER(Location) = 'erbil, iraq'

And as @TobySpeight already commented, you can then change it to an IN.

 LOWER(Location) IN ('sulaimani, iraq', 'erbil, iraq')

That won't work if you want to actually use LIKE to do a fuzzier match, e.g.

 LOWER(Location) LIKE '%, iraq'

But in that case, you could create a temporary table with the data as you want and query that, possibly joining the original table. By "data as you want", I mean lowercased and possible only the part after the ", " in this case. For other queries, you might have different requirements.
