I found a powershell script from: http://netsourcecode.blogspot.com/2011/12/listing-all-content-types-and-fields.html and modified it.

Try this:

$columnname = "StartDate"

write-host ("Looking for: " + $columnname)      
$url=  "http://localhost/"  
$site = get-spsite $url         
$web = $site.OpenWeb()      
foreach ($contenttype in $web.ContentTypes) {   
    foreach ($field in $contenttype.Fields) {
        if ($field.get_InternalName() -eq $columnname) {
            write-host("Content Type Name: " + $contenttype.Name + " has field: " + $field.get_InternalName())  
  • Perfect. Thank you Brandon. You rock. (well, rock is hard and senseless). You smooth. LOL Jul 2, 2012 at 15:52

    I changed get_InternalName to get_Title cause the column name was renamed. Thanks Jul 2, 2012 at 16:37

Instead of ListsFieldUsedIn, try to use $column.UsedInWebContentTypes()
