powershell find number of mailboxes per server

I am trying to find a way to to find the total number of mailboxes by group of mailbox servers. For example anything that begins with America add this up and supply a total number of mailboxes. Anyone have any idea on the best way to do this. This is what I have so far but its rerunning each time.

$america = (get-mailbox -resultsize:unlimited | ?{$_.servername -match "[^ameri*]"}).count
$mars = (get-mailbox -resultsize:unlimited | ?{$_.servername -match "[^mars*"}).count
$Railroad = (get-mailbox -resultsize:unlimited | ?{$_.servername -match "[^RAIL*"}).count

Get-mailbox -ResultSize "unlimited" | ? { $_.ServerName -like "$ServerQuery" } | measure
