“The US took formal possession of the islands in 1867. The laying of the trans-Pacific cable, which passed through the islands, brought the first residents in 1903. Between 1935 and 1947, Midway was used as a refueling stop for trans-Pacific flights. The US naval victory over a Japanese fleet off Midway in 1942 was one of the turning points of World War II. The islands continued to serve as a naval station until closed in 1993. Today the islands are a national wildlife refuge. From 1996 to 2001 the refuge was open to the public; it is now temporarily closed.”

As a territory of the USA I do not have many specific statistics for this territory in its own right.
There isn't much information in the database for Midway Islands, most likely because it is either a part of another country (i.e., a territory or posession) and therefore most international statistics are counted for the country as a whole, or, this is such an exotic place that little data exists about it.
