ordering a column by incidence

[colensa]

How can I order a column by the number of incidences of a value e.g. by the
number of times a name appears in that column, ordered by greatest to lowest.

I apologise in advance if this is facile, but it's got me!

One way is to use
=countif(a:a,a2) and copy down. Then sort by that column
