Frankfurt is today a relatively small city by international standards, although it is situated in a dense metropolitan area. The development of the city was determined by various political and economic factors over the centuries. In 1845 Frankfurt had just 58,500 inhabitants, while places like London were already big cities with more than a million people. Every city simply has its own development cycles.
The German metropolis has experienced an incredible economic boom over the past 50 years, which has also contributed to population growth. In the last 10 years or so, the population of Frankfurt has increased by around 16% to more than 750,000 today. A further growth in the number of inhabitants is predicted for the coming years, fueled in particular by its economic attractiveness.
The State Statistical Office of Hesse is forecasting a population of around 870,000 in 2040. However, it is uncertain how long it will take Frankfurt to actually become a metropolis of over a million people. The dynamic development of the city will mean that there will also be more high-rise buildings in the future.
