the short answer
The US Census Bureau groups the 50 states into 4 regions: the Northeast (9 states), the Midwest (12), the South (16, plus Washington, D.C.) and the West (13), split into 9 divisions. School maps often use 5 regions instead: Northeast, Southeast, Midwest, Southwest and West.

The Census Bureau's regions are the official ones. The Bureau reports its statistics by them, and other federal agencies, such as the Energy Information Administration, publish data by the same regions. The 5-region map is a teaching map: it moves a few states around and splits the South in two.

What states are in the Northeast?

The Northeast has 9 states in two divisions, New England and the Middle Atlantic. It has the fewest states of the four, and the National Geographic 5-region map has exactly the same 9. New England is also the everyday name for the six states in that division.

What states are in the Midwest?

The Midwest has 12 states in two divisions. Until June 1984 the Census Bureau called it the North Central Region, which is why its divisions are East North Central and West North Central. The school map's Midwest is the same 12.

What states are in the South?

The South has the most states and the most people, with 16 states plus Washington, D.C. in three divisions. It has a few surprises: Delaware and Maryland are Southern states in the Census scheme, and so are Texas and Oklahoma.

This is where the school map differs most. It splits the South into a Southeast of 14 states, which is the Census South without Oklahoma and Texas, and a Southwest that joins those two with Arizona and New Mexico.

What states are in the West?

The West has 13 states in two divisions, Mountain and Pacific. Alaska and Hawaii are both in the Pacific division. On the school map the West has 11, because Arizona and New Mexico go to the Southwest.

The 5 US regions taught in school

National Geographic's education site groups the states into 5 regions by where they sit on the continent: Northeast, Southeast, Midwest, Southwest and West. It is a teaching map rather than an official scheme, and it leaves Washington, D.C. out. Other 5-region maps differ at the edges, and Delaware and Maryland sometimes go to the Northeast, so the table here follows National Geographic.
