The following are approximate tallies of current listings by county. These counts are based on entries in the National Register Information Database as of March 13, 2009 and new weekly listings posted since then on the National Register of Historic Places web site. There are frequent additions to the listings and occasional delistings and the counts here are approximate and not official. New entries are added to the official Register on a weekly basis. Also, the counts in this table exclude boundary increase and decrease listings which modify the area covered by an existing property or district and which carry a separate National Register reference number. , in Carroll County , designed by Eliel Saarinen, in Bartholomew County , destroyed by fire in 2002 but still NRHP-listed, in Parke County , in Vigo County , Vanderburgh County , designed by
