“The US took possession of the island in 1857. Its guano deposits were mined by US and British companies during the second half of the 19th century. In 1935, a short-lived attempt at colonization began on this island but was disrupted by World War II and thereafter abandoned. [...] Managed by the Fish and Wildlife Service of the US Department of the Interior.”

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 Baker Island, most likely because it is either a part of another country (i.e., a territory or possession) 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.
