A new food insecurity study highlights how difficult it is to get accurate college student survey data. 

"The researchers analyzed multiple studies on food insecurity and found discrepancies in the way hunger is measured. Those discrepancies cast doubt on estimates of the share of college students who are reportedly hungry or food insecure, according to a paper the researchers, Cassandra J. Nikolaus, Breanna Ellison and Sharon Nickols-Richardson, published in PLOS ONE last week."
