Prosperity across the United States

Our United States Prosperity programme is focused on developing a comprehensive picture of prosperity for all 50 states of the Union as well as Washington D.C., and across hundreds of counties in a number of selected states.


The United States’ overall economy is world-leading. It is open, with well-developed infrastructure, competitive markets, and plentiful access to finance. In the main, its institutions are robust, its education system is one of the best in the world, and the majority of citizens feel connected to each other and engaged in society. However, the U.S. under-performs in areas such as safety and security, health, and living conditions, and has not advanced in our global Prosperity Index rankings over the last 10 years.

We wanted to understand why the United States’ undeniable long-term economic success is not translating fully into social wellbeing. In 2019, with the generous support of The Leona M. and Harry B. Helmsley Charitable Trust, we published the inaugural United States Prosperity Index, measuring prosperity across its institutional, economic, and social dimensions for all the different states and regions of the U.S. In 2020, with additional support from The Robert Wood Johnson Foundation and The Walton Family Foundation, we updated the state level Index and published a brand-new, in-depth analysis of prosperity across 829 counties in eight selected states (California, Colorado, Georgia, Iowa, Montana, New York, Oklahoma, and Texas).

Led by Shaun Flanagan our United States Prosperity programme offers new insight to show where targeted policy interventions could help every state and county become more prosperous.
