This table was created using data presented in the United States Department of Agriculture (USDA) 2007 and 2017 census publications, available online from the National Agricultural Statistic Service by Danae Peckler (published in the Spring 2020 issue of The Barn Door).
State- and County-level data gathered as a result of the NBA’s “Barn Question” is available via the NASS link above – see Chapter 2 ‘s “Table 43: Selected Practices 2017 and 2012.” Comparing 2017 County-level statistics to those in the 2007 Ag Census may provide individuals and elected officials greater insight on the conditions of historic barns on farms at the local level.
