Lloyd’s City Risk Index Methodology

The Cambridge Global Risk Index research track analyses the combined damage inflicted on global cities by a comprehensive set of significant and recurrent threats. 

Overview

We consider some 22 threats in five broad threat classes:

  • Natural catastrophe and climate, including threats such as earthquake and windstorms.
  • Finance, economics and trade, including threats such as market crashes, and commodity price shocks.
  • Geopolitics and security, including political instability, conflicts and terrorism.
  • Technology and space, for example, cyber catastrophe.
  • Health and humanity, for example pandemics and famines. 

This report documents the methodology used for the Lloyd's City Risk Index 2018 analysis. It describes how cities were selected, GDP projections, and the updated resilience ratings. It outlines the catastronomics methodology and how GDP@Risk is calculated.
