18 SHELBY COUNTY v. HOLDER Opinion of the Court west Austin, 557 U. S., at 204. As we explained, a statute’s “current burdens” must be justified by “current needs,” and any “disparate geographic coverage” must be “sufficiently related to the problem that it targets.” Id., at 203. The coverage formula met that test in 1965, but no longer does so. Coverage today is based on decades-old data and eradicated practices. The formula captures States by reference to literacy tests and low voter registration and turnout in the 1960s and early 1970s. But such tests have been banned nationwide for over 40 years. §6, 84 Stat. 315; §102, 89 Stat. 400. And voter registration and turnout numbers in the covered States have risen dramatically in the years since. H. R. Rep. No. 109–478, at 12. Racial disparity in those numbers was compelling evidence justifying the preclearance remedy and the coverage formula. See, e.g., Katzenbach, supra, at 313, 329–330. There is no longer such a disparity. In 1965, the States could be divided into two groups: those with a recent history of voting tests and low voter registration and turnout, and those without those characteristics. Congress based its coverage formula on that distinction. Today the Nation is no longer divided along those lines, yet the Voting Rights Act continues to treat it as if it were. B The Government’s defense of the formula is limited. First, the Government contends that the formula is “reverse-engineered”: Congress identified the jurisdictions to be covered and then came up with criteria to describe them. Brief for Federal Respondent 48–49. Under that reasoning, there need not be any logical relationship between the criteria in the formula and the reason for coverage; all that is necessary is that the formula happen to capture the jurisdictions Congress wanted to single out.
