"One in five rural counties had child poverty rates of over 33 percent in 2009/13, but another one in five had child poverty rates of less than 16 percent," McGranahan writes. "Overall, county average rates of child poverty rose from 20 percent to 25 percent over 1999-2009/13, with the proportion of counties with child poverty rates of over 33 percent doubling in this period. Meanwhile, estimated child poverty rates declined in one in five counties."
The report is accompanied by an interactive map giving data for each county. Here's a screen grab of the map:
They also noted that counties that rely on manufacturing had the greatest number of poor children. Tim Marema notes for the Daily Yonder, "In rural manufacturing counties, child poverty climbed by 45 percent from 1999 to 2009-2013. During the same period, roughly one in four rural manufacturing jobs disappeared, according to the report. In contrast, agriculture-dependent rural counties saw an increase of about 6 percent in child poverty. Child poverty increased by about 5 percent in rural counties that depend heavily on the recreation industry. In mining counties child poverty also grew by about 5 percent. And counties that don’t fall into one of the other economic categories saw a child-poverty increase of 22 percent."
