A Couple Depressing Maps

A little explanation:

A majority of public school children in 17 states, one-third of the 50 states across the nation, were low income students – eligible for free or reduced lunches – in the school year that ended in 2011. Thirteen of the 17 states were in the South, and the remaining four were in the West. Since 2005, half or more of the South’s children in public schools have been from low income households.
Low income is defined as below 130% of the poverty line and these kids qualify for a free lunch.  Poverty also significantly impacts reading test scores, school opportunities and the ability to go to college.  When one just looks at cities, the situation is much worse.  Kids in public schools who are low income account for 59.8% on average of all students in K-12 public schools.  Any urban area with a population greater than 100,000 is teeming with America's poor.  Mississippi had the highest rate of low income students, 83%, In New Jersey cities 78% of the students are poor and Louisiana, Illinois and Oklahoma all low income rates of greater than 70% for their K-12 students.

There is a little nuance to this information, as whites fled to private schools throughout the south after integration took place.  But still, the numbers are very depressing.  These ans more maps of economic  hardship are here.
