Counting All Instances in a column

Hey All - looking at how to get a count of all instances in a column. For example, I have a data set of 100 rows and one of the columns will be City. So I want to count all the instances of each city in that column. So a return set might come back with Seattle 30, LA 25, Portland 20, Boise 10, Vancouver 5, NY 4, Miami 3, Austin 2, Fargo 1. 

So i'm not just looking to do a count on one city name but a count of all values in that column.  My end result is to take this count, order it descending, and then take the top 5 values and throw that into a Power View report. 

Thanks for your replies.
