Lodz is First City to Receive a Resistance-to-Shocks Rating

Singapore, December 7-th, 2017. The City of Lodz, Poland, has received a Resistance to Shocks Rating, which measures the capacity to absorb sudden destabilizing events. The result is a high rating of 86%, corresponding to a four-star rating on a scale from one to five stars. In addition, the rating provides a ranking of all parameters used in the analysis, indicating which ones, and in what measure, constitute sources of resilience or fragility.

"This is the first time that a systemic Resistance to Shocks Rating has been computed for a city. We are thankful to the authorities of Lodz for allowing us to perform this pioneering analysis", said Dr. J. Marczyk, the Chairman of Universal Ratings. "Cities are large and highly complex systems of infrastructures and processes which possess their own specific dynamics and which interact with a rapidly changing society and economy. Such interactions can be non-intuitive and difficult to grasp. However, it is important for the authorities to comprehend the said dynamics, in order to better govern the city and to plan its development on more systemic and scientific grounds",  he concluded.

The data which has been used to compute the systemic Resistance to Shocks (RtS) rating of the city spanned the following dimensions:

  • Labor market

  • Construction and Real Estate

  • Budget

  • Central Statistics Office, GUS

The data covers the period 2002-2006 for a total of 364 parameters. Collaboration is continuing to extend the scope of the analysis, embracing such dimensions as energy and transportation.

Łódź is a vibrant city in central Poland, known as a former textile-manufacturing hub. It has over 750 000 inhabitants, making it Poland's third largest city. For more information see here.
