Emma Brown of the Washington Post reports a dramatic increase in student poverty rates and increased segregation of the poorest students since the “Great Recession” of 2008.

The data are supplied by a nonprofit called Edbuild.

It includes a stunning comparison between maps of the United States, showing student poverty, in 2006 and 2013.

Student poverty has increased most in the South and the MidWest.

New Mexico saw a huge increase in student poverty, from half its students to 87%.

The state that has seen the most growth in student poverty is Florida.

Schools and teachers, of course, will be blamed and expected to cure what is a structural economic problem.

The Common Core and rigorous tests will not fix poverty.

This is an appalling commentary on what matters most in the United States today.
