Detailed analysis of Georgia and South Carolina Counties.

<p>Prediction about the emergence of a creole language in those Counties and Parishes of Georgia (GE) and South Carolina (SC) for which census data collected in year 1790 are available. Blue Counties lie below the transition stripe shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120771#pone.0120771.g001" target="_blank">Fig 1</a> (see also Fig H and I in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120771#pone.0120771.s001" target="_blank">S1 Supporting Information</a>) so that our model predicts that creole did not emerge. On the contrary, orange Counties lie above the transition stripe where our model predicts the formation of creole. The green Counties lie in the grey transition region. Although modern County boundaries are shown, only the labels corresponding to the Counties existing in year 1790 are displayed. Since only part of Georgia was colonized in 1790, modern Counties that were not yet colonized are depicted in white (the western part of modern Georgia has been cut out). The dark gray Counties, though already existing in 1790, were not involved in the census operations. The boundary between GE and SC is marked by the river Savannah.
