The Louisiana Community Oil Spill Survey (COSS) dataset

This article presents an overview of the Louisiana Community Oil Spill Survey (COSS), the dataset used in “Community Sentiment following the Deepwater Horizon Oil Spill Disaster: A Test of Time, Systemic Community, and Corrosive Community Models” [1] as well as elsewhere [2–6]. The COSS, administered by the Louisiana State University's Public Policy Research Laboratory, consists of five waves of cross-sectional trend data attuned to the characteristics and effects of the 2010 BP Deepwater Horizon (BP-DH) oil spill on those coastal Louisiana residents most affected by the disaster. Respondents were randomly drawn from a list of nearly 6,000 households in the coastal Louisiana zip codes located in Lafourche Parish, Plaquemines Parish, Terrebonne Parish, and the community of Grand Isle. COSS data were initially collected in June 2010 when oil was still flowing from the wellhead, with additional data waves, collected in October 2010, April 2011, April 2012, and April 2013. The respective response rates were: June 2010, 20%; October 2010, 24%; April 2011, 25%; April 2012, 20%; and April 2013, 19%.
