They were collected in The Delta, specifically, in Greenwood, Mississippi.
According to the US Census, Greenwood has a population of just over 15,000 folks, 72% of whom have graduated from high school (5% fewer than Mississippi total), and 19% of whom have a bachelor's degree or higher (same as Mississippi total).
The median household income is almost $25,000 (compared to $37.8k in Mississippi).
At 48%, Greenwood's home ownership rate is well below Mississippi's 70%. But-- and folks, keep in mind it's The Delta-- the "median value of owner-occupied housing units, 2006-2010" (homes and condos, right?) is about $81k, far less than Mississippi overall ($96.5k ), but still greater than my little county's $72.5k.
Thirty-six percent of Greenwood's population is living below the poverty level (21% in Mississippi).
Here's an interesting statistic. The percentage of foreign born persons in Greenwood is 3.1. As a percentage, there are a lot more foreign born persons in Greenwood compared to my little county (1%) and Mississippi (2.2%). Heck, statistically it's probably the same as in Starkvegas (2.9%; Go Dawgs), but no where near large as in that Rebellious Town Up North (6.3%).
Based on these statistics, what picture are you painting of Greenwood's population?
