A projection for the development of the German population over the next 40 years in relation between ethnic Germans (yellow) and immigrants (dark red) and both combined (organge) - assuming the birth rates are the same and no more immigration occurs. Looks like we're going to be on par until the mid of the century. Given the current birth rates and the ongoing open border policy, this point could be reached 5-10 years before and then quickly jump to 60:40 against ethnic Germans. Too good, such very long-term projections are not worth too much. But the scenario does give me the chills..
