The article presents the results of a projection of the regional economic development of East Germany and Saxony up to 2030. The results indicate that the growth prospects for East Germany are positive in the long term, but are still below an annual average of one percent. They therefore lag behind the likely development for West Germany, which is due in particular to the even more unfavorable demographic development in East Germany (and also in Saxony), which limits more favorable employment development in the long term. When assessing the results, however, it should also be noted that the central indicator of prosperity, the per capita gross domestic product, will develop significantly more favorably. According to the projection calculations carried out, East Germany’s per capita gross domestic product is growing by an annual average of 1.33%, which is about the same rate as in West Germany. This is the positive downside of the unfavorable demographic development.
