Ostsiedlung also led to a rapid population growth throughout East Central Europe.  During the 12th and 13th centuries, the population density in persons per square kilometre increased, for example, from two to 20–25 in the area of present-day Saxony, from 6 to 14 in Bohemia, and from 5 to in Poland (30 in the Cracow region).  In his 1999 essay summarizing the state of research, Piskorski said that the increase was due to the influx of settlers on the one hand and an increase in indigenous populations after the colonization on the other hand: settlement was the primary reason for the increase . in the areas east of the Oder , the Duchy of Pomerania , western Greater Poland , Silesia , Austria , Moravia , Prussia and Transylvania ( Siebenbürgen ), while in the larger part of Central and Eastern Europe indigenous populations were responsible for the growth.  In an essay of 2007, the same Piskorski said that "insofar as it is possible to draw conclusions from the less than rich medieval source material, it appears that at least in some East Central European territories the population increased significantly. It is however possible to contest to what extent this was a direct result of migration and how far it was due to increased agricultural productivity and the gathering pace of urbanization."  In contrast to Western Europe , this increased population was largely spared by the 14th-century Black Death pandemic . 
Chris, you missed the boat a bit with your comment about the fudge. Solvang is home to three authentic Danish bakeries, all founded by Danish bakers who have trained their staff in the art of Danish pastry. It is home to native Danish speakers who carry on the traditions of their homeland both privately and in the community. And it’s home to the Elverhoj Museum, a wonderful collection of art and artifacts from Solvang’s early days as a Danish settlement. Hands down, it’s the best “faux” Euro village in the ., and I really believe that calling it “faux” is a bit of an insult to the early Danish settlers who founded and built the community.
