Can you name all 50 states from memory? This name all 50 states challenge gives you eight minutes to type every state in the union, from Alabama to Wyoming. Spelling is forgiving and two-letter postal codes count, so the only real test is recall. Most people stall somewhere in the high forties, usually on a small Northeastern state or a big empty one out West.
The United States reached 50 states in 1959, when Alaska joined in January and Hawaii followed in August. The Census Bureau sorts them into four regions: the Northeast (9 states), the Midwest (12), the South (16) and the West (13). Those groupings are a handy scaffold, because recall works best when you sweep a map in order rather than firing off names at random.
Try walking the map: start in Maine, work down the Atlantic coast to Florida, sweep west along the Gulf to Texas, climb the Great Plains to North Dakota, then finish with the Mountain West and the Pacific. The states people forget most are the ones that sit in the middle of a cluster, so double-check New England, the Dakotas and the Four Corners. Pairs help too: there are two Carolinas, two Dakotas, a Virginia and a West Virginia, and four states that begin with "New".
