- Brooklyn is a borough of New York City located at the westernmost end of Long Island in the State of New York. Formerly an independent city, the borough is coextensive with Kings County, one of twelve original counties established under British rule in 1683 in the then Province of New York. As of the 2020 United States census, the population stood at 2,736,074, making it the most populous of the five boroughs of New York City, the most populous county in the State of New York, and the ninth most populous county in the United States. In 2022, the population density of Brooklyn was recorded at 37,339.9 inhabitants per square mile (14,417.0/km2), making it the second most densely populated county nationwide, behind only Manhattan (New York County). Had Brooklyn remained an independent city, it would today be the fourth most populous American city after New York, Los Angeles, and Chicago.
- Clark County — Thumbnail History (historylink.org)
Local history buffs call Clark County the “Cradle of Pacific Northwest History,” reflecting the importance of the 628-square-mile southwestern Washington county as the scene of key historical developments. Here the Lewis and Clark expedition arrived in 1805, the British Hudson’s Bay Company established Fort Vancouver in 1825, and the town of Vancouver was incorporated in 1857. The county’s location first made it an entrepôt (trading center), then an agricultural area. The region developed in agriculture, lumber, and fishing, and later in shipbuilding and aluminum. In recent times, energy from hydroelectric projects on the Lewis and Columbia rivers has fueled development as a manufacturing center.
