The Broadband Investment Index (BIIX) subsumes 21 different indicators of the social, entrepreneurial, political, and infrastructural preconditions for building investments in Germany. We computed the BIIX for 402 rural districts.

Results of the BIIX indicate that the rural districts with the best preconditions for broadband investments are located in the Southern part of Germany. Many rural districts in Northern and Western Germany qualify for good to very good preconditions as well. According to the ranking, many rural districts in the new federal states have relatively weak preconditions for broadband investments. In Berlin, the urban centers of Thuringia and Saxony, and parts of Brandenburg, however, preconditions for broadband investments are still average to good.

How can the preconditions for broadband investments in rural districts be improved? The study “The impact of broadband on growth and productivity” (www.micus.de/59a_bb-final_en.html), written by MICUS CEO Dr. Martin Fornefeld on behalf of the European Commission, shows that economic growth and production improve when broadband supply enhances.

Would improving Internet Access connectivity also have a positive impact on your  rural district in general? The BIIX-Calculator computes the new BIIX rank of your rural district after improving broadband supply in your region. Try it out!
