The McKinsey Health Institute, or MHI, is an enduring, non-profit-generating institute within McKinsey & Co. It was founded on the conviction that, over the next decade, humanity could add as much as 45 billion extra years of higher-quality life (roughly six years per person on average — and substantially more in some countries and populations). MHI’s mission is to catalyze the actions needed across continents, sectors, and communities to realize this possibility.
