How were Danish and German speakers distributed across Schleswig before the war?

Prior to the German-Danish War, the population distribution of Schleswig was characterized by distinct linguistic and cultural zones.12

The northern portion of the duchy was predominantly Danish-speaking, while the southern portion was primarily German-speaking. The central region and the northern towns featured a mixed population where both Danish and German influences were present. This demographic complexity, alongside the political status of the region, fueled the Schleswig-Holstein question, as nationalist movements in both Denmark and the German Confederation sought to align the territory with their respective nations. In contrast, the population of the neighboring duchy of Holstein was almost entirely German.12
