To fix the issue you can do From your comment I understand that providing you with SQL queries could help.
This simple aggragated query will return the REFERRALs with most occurences (all time), highest on top.
code :
SELECT referral, COUNT(*) 
FROM table
GROUP BY referral
ORDER BY COUNT(*) DESC
SELECT referral, COUNT(*) 
FROM table
WHERE YEAR(sigmup_date) = YEAR(NOW()) AND MONTH(sigmup_date) = MONTH(NOW()) 
GROUP BY referral
ORDER BY COUNT(*) DESC

this one helps. The delegate for the make (materialization) is pretty versatile and flexible, but IMO makes for a bit of unnecessary work in the vast majority of cases. In terms of what it does - they use the delegate as a callback to get the caller to specify how to read the record.
Note, since they don't expect the consumer to change record, they should probably be exposing IDataRecord, not IDataReader (any reader also implements record).
code :
while(reader.NextResult()) {}
var cust = connection.Query<Customer>("MyStoredProcedure",
     new { CustomerId = customerId },
     commandType: CommandType.StoredProcedure).Single();
