The most densely populated areas are the fertile foothills, known as the Lübbecke Loessland (Lübbecker Lößland); this is where almost all the villages are found. The average population density here is 600-1000 inhabitants/km2. The lowlands south of the canal, apart from Lübbecke's industrial area, are very sparsely populated. The Wiehen Hills themselves are unpopulated as is the Großer Torfmoor.
