Try this
Select * From (select 'Number of users:' Descrip, Count(A.UserID) Value From tblUser a, tblUserDetails b where a.UserID = b.UserID
Union
select 'Number of over 18''s:' Descrip, Count(IsOver18) Value From tblUser a, tblUserDetails b where a.UserID = b.UserID
Union
select 'Number of users in USA:' Descrip, Count(IsInUSA) Value From tblUser a, tblUserDetails b where a.UserID = b.UserID
Union
select 'Number who want to receive info:' Descrip, Count(isReceiveInfo) Value From tblUser a, tblUserDetails b where a.UserID = b.UserID ) xyz

asyforce-solution goes for the layout, mine was focused on the counting

Differences
1)  mine  :   ,sum(isnull(isOver18,0)) as nbrOver18      
When isOver18 = 1 when true then sum works fine, must be 0 or null for false
2) astforce:  count(IsOver18)
Counts the times column IsOver18 is filled up, so must be NULL when false

OK Guys

I get

The count aggregate operation cannot take a uniqueidentifier data type as an argument

if I try to do a count as I don't think you can do it on GUIDs?

Count(*) in case of count(UserID) will do the trik.

I've already counterd that question, see differences.
