Bavaria is the largest state in the Federal Republic of Germany. Over twelve million people live and work in its over 70,000 square kilometres, divided into seven administrative districts. As well as the eight cities with more than 100,000 inhabitants, including the two largest, Munich and Nuremberg, the rural areas are also very significant for Bavaria. They make up around 85% of the state's area and almost eight million people, or almost 60% of the Bavarian population, live, work and do business there. Every part of the state has business expertise and technological know-how.
