¹ NAEP region is the "state-based" NAEP region. NAEP regions (the state-based version and the earlier version which crossed state boundaries) were used as strata in 2002 NAEP and in earlier NAEP surveys rather than Census region because the populations in the NAEP regions were at that time close to equal (a desirable property of strata). NAEP region Northeast consists of all states in the Northeast Census region, plus Maryland, Delaware, and the District of Columbia. NAEP region Central is the same as the Midwest Census region. NAEP region West is the same as the West Census region, plus Texas and Oklahoma. NAEP region Southeast consists of all states in the South Census region except Maryland, Delaware, the District of Columbia, Texas, and Oklahoma.
