Dictionary tables can provide u with info. as to when was the object last analyzed. However, it would be ur call to define an object as "stale" i.e. would it be a week old or a month old or a year old. For e.g.

SELECT table_name, num_rows, last_analyzed
FROM user_tables;

We use this query  :

select  ---*
table_name, partition_name, object_type
from user_tab_statistics  -- you can even use dba_tab_statistics
where stale_stats = 'YES';

Thanks
