The area was seen as an impediment; the purpose was simply to get to the other side. The Great Plains are now often referred to as \u201cflyover country,\u201d a disparaging description indicating that most people simply fly over. The \u201cflyoverness\u201d of the Great Plains can be examined through air population, the total number of people flying above the earth at any point in time. The instantaneous location of aircraft can now be tracked through an extensive network of ground aircraft sensors based on ADS-B (Automated Dependent Surveillance-Broadcast) that provides the position of an aircraft along with its identification, aircraft type, altitude, and speed. Air population can then be estimated by multiplying the number of seats for each aircraft by the current seat occupancy rate. This population is further divided by state and county. Maps show the total air population, the density of air population (population\/area), and the ratio of air population to ground population. While high ground population areas also have a high air population, \u201cflyover\u201d states have a higher ratio of air population to ground population. The analysis also shows that many counties in the Great Plains regularly have more people above them than live on the ground. <\/jats:p>","DOI":"10.3138\/cart.53.1.2017-0022","type":"journal-article","created":{"date-parts":[[2018,3,21]],"date-time":"2018-03-21T19:05:06Z","timestamp":1521659106000},"page":"36-51","source":"Crossref","is-referenced-by-count":0,"title":["Air Population over the Great Plains"],"prefix":"10.3138","volume":"53","author":[{"given":"Michael P.","family":"Peterson","sequence":"first","affiliation":[{"name":"Department of Geography and Geology\u00a0\/ University of Nebraska at Omaha\u00a0\/ Omaha\u00a0\/ NE\u00a0\/ USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Hunt","sequence":"additional","affiliation":[{"name":"Department of Geography and Geology\u00a0\/ University of Nebraska at Omaha\u00a0\/ Omaha\u00a0\/ NE\u00a0\/ USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1696","reference":[{"key":"B1","unstructured":"Badger, Emily. 2013. \u201cThe Most Important Population Statistic That Hardly Ever Gets Talked About.\u201d City Lab (formerly The Atlantic Cities), May 30."},{"key":"B2","doi-asserted-by":"crossref","first-page":"880","DOI":"10.1007\/978-0-387-35973-1_1005","volume-title":"Encyclopedia of GIS","author":"Bhaduri Budhendra.","year":"2008"},{"key":"B3","unstructured":"Biggs, John. 2013. \u201cA Tiny Computer Attracts a Million Tinkerers.\u201d The New York Times, January 30, B8"},{"issue":"4","key":"B4","doi-asserted-by":"crossref","first-page":"375","DOI":"10.1016\/S0378-8733(99)00019-2","volume":"21","author":"Borgatti S.P.","year":"2000","journal-title":"Social Networks"},{"key":"B5","unstructured":"Bureau of Transportation Statistics. 2017. \u201cLoad Factor \u2013 Passenger-Miles as a Proportion of Available Seat-Miles in Percent.\u201d US Department of Transportation. https:\/\/www.transtats.bts.gov\/Data_Elements.aspx?Data=5"},{"issue":"80","key":"B6","doi-asserted-by":"crossref","first-page":"39","DOI":"10.14714\/CP80.1314","author":"DeBoer Mike.","year":"2015","journal-title":"Cartographic Perspectives"},{"key":"B7","unstructured":"FlightAware ADS-B. 2017. \u201cFlightAware ADS-B Statistics.\u201d http:\/\/flightaware.com\/adsb\/stats\/"},{"key":"B8","unstructured":"FlightRadar24. 2017. \u201cHow It Works.\u201d https:\/\/www.flightradar24.com\/how-it-works"},{"key":"B9","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-319-41262-7","volume-title":"Economic Cycles, Crises, and the Global Periphery","author":"Grinin L.","year":"2016"},{"key":"B10","unstructured":"Jadhav, A. 2016. \u201cAirline Metrics: Passenger Load Factor.\u201d http:\/\/airlinegeeks.com\/2016\/01\/29\/airline-metrics-passenger-load-factor\/"},{"key":"B11","unstructured":"Martin, H. 2014. \u201cAirlines Fill Planes to Record Capacity as Demand Continues to Grow.\u201d 13 March, B2. http:\/\/www.latimes.com\/business\/la-fi-mo-airlines-fill-planes-to-record-capacity-20140313-story.html"},{"key":"B12","unstructured":"Pietersz, G. 2014. \u201cPLF (Passenger Load Factor), Moneyterms: Investment, Finance and Business Explained.\u201d http:\/\/moneyterms.co.uk\/plf-passenger-load-factor\/"},{"issue":"4","key":"B13","doi-asserted-by":"crossref","first-page":"422","DOI":"10.1111\/1475-4762.00048","volume":"33","author":"Porter Rob.","year":"2001","journal-title":"Area"}],"container-title":["Cartographica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/utppublishing.com\/doi\/pdf\/10.3138\/cart.53.1.2017-0022","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,13]],"date-time":"2025-03-13T10:35:36Z","timestamp":1741862136000},"score":1,"resource":{"primary":{"URL":"https:\/\/utppublishing.com\/doi\/10.3138\/cart.53.1.2017-0022"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,3]]},"references-count":13,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2018,3]]}},"alternative-id":["10.3138\/cart.53.1.2017-0022"],"URL":"https:\/\/doi.org\/10.3138\/cart.53.1.2017-0022","relation":{},"ISSN":["0317-7173","1911-9925"],"issn-type":[{"type":"print","value":"0317-7173"},{"type":"electronic","value":"1911-9925"}],"subject":[],"published":{"date-parts":[[2018,3]]}}}
