The Berlin Institute for Population and Development or Berlin-Institut für Bevölkerung und Entwicklung is an autonomous scientific research institute who aims at improving the way in which international demographic change is perceived and dealt with in the context of sustainable development. To reach this goal, the institute publishes studies and discussion papers. The institute is headed by Reiner Klingholz, who studied chemistry, earning a PhD in molecular biology. Earlier in his career, Reiner Klingholz worked as a journalist for the German weekly Die Zeit and the bi-annual magazine Geo Wissen. The institute is financed by contributions, project funds, earnings from and donations to the Foundations endowment. In order to ensure its independent status, the Director of the Berlin Institute is instructed by the steering committee to maintain a balance between the different funding sources. The Institutes status is recognized by the German tax authorities (North Hannover Office). It was established on November 29, 2000, by Marlene von Reichenbach. During the initial years it received broad support from the William and Flora Hewlett Foundation. It is not permitted for sponsors to influence conclusions of the Berlin Institutes studies.
