I just copied and pasted your query into Access 2010 and it worked correctly. Verify that you can update the values in your linked table by opening it in Datasheet View and manually changing one of the [Y1977] values. If you cannot update the linked table then you'll need to confirm that
Your ODBC connection actually has permission to UPDATE the table on the SQL Server.
Your Access linked table has a Primary Key defined. (Open the Access linked table in Design View and check for the little gold key icon(s) as in the screenshot below.)
