This document summarizes the key findings from the Centre for Cities' annual Cities Outlook report for 2014. It notes that cities are driving the UK's economic recovery, accounting for over half of jobs, population and economic output, yet there is significant variation in economic performance between cities. While London and some other large cities are seeing strong private sector job growth, many cities continue to struggle. It argues that greater devolution of powers, taxes, and spending to cities could help unleash their economic potential and better tailor policies to local needs. Overall, the report emphasizes that cities will be crucial to improving living standards and prosperity, and should be at the heart of the political debate in the run-up to the next general election.
