Answer by taking a quote from the following article:

The Menominee (also spelled Menomini, derived from the Ojibwe language word for "Wild Rice People;" known as Mamaceqtaw, "the people," in the Menominee language) are a federally recognized nation of Native Americans, with a 353.894 sq mi (916.581 km2) reservation in Wisconsin. Their historic territory originally included an estimated 10 million acres (40,000 km2) in present-day Wisconsin and the Upper Peninsula of Michigan. The tribe currently has about 8,700 members. The tribe was terminated in the 1950s under federal policy of the time which stressed assimilation.

The Menominee Indian Reservation is located in northeastern Wisconsin. For the most part, it is conterminous with Menominee County and the town of Menominee, which were established after termination of the tribe in 1961 under contemporary federal policy whose goal was assimilation. The tribe regained its federally recognized status and reservation in 1975.  The reservation was created in a treaty with the United States signed on May 12, 1854 in which the Menominee relinquished all claims to the lands held by them under previous treaties, and were assigned 432 square miles (1,120 km2) on the Wolf River in present-day Wisconsin. An additional treaty, which they signed on February 11, 1856, carved out the southwestern corner of this area to create a separate reservation for the Stockbridge and Lenape (Munsee) tribes, who had reached the area as refugees from New York state. The latter two tribes have the federally recognized joint Stockbridge-Munsee Community.  After the tribe had regained federal recognition in 1973, it essentially restored the reservation to its historic boundaries in 1975. Many small pockets of territory within the county (and its geographically equivalent town) are not considered as part of the reservation. These amount to 1.14% of the county's area, so the reservation is essentially 98.86% of the county's area. The largest of these pockets is in the western part of the community of Keshena, Wisconsin. The reservation includes a plot of off-reservation trust land of 10.22 acres (41,400 m2) in Winnebago County, Wisconsin to the south, west of the city of Oshkosh. The reservation's total land area is 353.894 sq mi (916.581 km2), while Menominee County's land area is 357.960 sq mi (927.11 km2).  The small non-reservation parts of the county are more densely populated than the reservation, holding 1,337 (29.3%) of the county's 4,562 total population, as opposed to the reservation's 3,225 (70.7%) population, as of the 2000 census.  The most populous communities are Legend Lake and Keshena. Since the late 20th century, the members of the reservation have operated a number of gambling facilities in these communities as a source of revenue. They speak English as well as their traditional Menominee language, one of the Algonquian languages. Current population of the tribe is about 8,700.
