    sort column based on number of duplicate values

    Hello all,

    I have countries listed in Column D with many duplicates. My goal is to sort Column D, from highest to lowest, based on the number of duplicates:

    So, this:

    Country
    US
    US
    US
    US
    UK
    UK
    Italy
    Italy
    Italy
    Italy
    Italy
    Italy

    would become this:
    Italy
    Italy
    Italy
    Italy
    Italy
    Italy
    US
    US
    US
    US
    UK
    UK

    The following code works, but is very slow (I have 20,000+ rows of data). Are there any faster alternatives?

    (Note: I have data in column A which I use to define the last row of data -LR-)

    Thanks, AndyLitch. This works, but is not really speeding things up for me. I see that you are setting the application.calculation to xlmanual. Should that speed things up?

    Yes, it should speed it up somewhat because i believe when you autofill, it keeps recalculating...

    You could also try Application.ScreenUpdating = false/true

    Thanks you AndyLitch. I have added the Application.ScreenUpdating in addition to the manual application.calculation. It still isn't quite instantaneous, but given the nature of problem, perhaps this is as fast as I should expect it to run. Thanks for the help!

    The other thing which will speed it up a tad more is to swop the autofil for copy/paste
