I suggest you to use osm-history-splitter (to obtain some places) and
Togheter with osm-history-renderer there is the program osm-history-import
This create for you some postgis tables, with this table you can query the
database and find the answer to your questione.
In any case this doesn't solve the problem of the dimension, but, i think,
after the import you have all the data to have more statistics.
