How can I get the count of how many times a string appears in my list? [closed]

I have a list of strings, like so:

"aa bb", "cc dd", "aa bb", "aa bb", "cc dd", "ww ss", "ss ss", "kk mm"

I know WordCounts will return the numbers of every single word, but I want to the word group numbers, i.e., "aa bb" 3 times, and "cc dd" 2 times. How can I do this?

You can try Tally

lst = "aa bb", "cc dd", "aa bb", "aa bb", "cc dd", "ww ss", "ss ss", "kk mm";
Tally[lst]

Mathematica graphics

As J.M. says in his comment below, Counts will give the same information as an association.

Counts[data]

<|"aa bb" -> 3, "cc dd" -> 2, "ww ss" -> 1, "ss ss" -> 1, "kk mm" -> 1|>

This is equivalent to

Rule @@@ Tally[data] // Association
