Digital capabilities, adoption, and usage are evolving at a supercharged pace. While most users scramble just to keep up with the relentless rate of innovation, the sectors, companies, and individuals on the digital frontier continue to push the boundaries of technology use—and to capture disproportionate gains as a result. The pronounced gap between the digital “haves” and “have-mores” is a major factor shaping competition at all levels of the economy. The companies leading the charge are winning the battle for market share and profit growth; some are reshaping entire industries to their own advantage. Workers with the most sophisticated digital skills are in such high demand that they command wages far above the national average. Meanwhile, there is a growing opportunity cost for the organizations and individuals that fall behind. Our new McKinsey Global Institute (MGI) report, Digital America: A tale of the haves and have-mores, represents the first major attempt to measure the ongoing digitization of the US economy at a sector level. It introduces the MGI Industry Digitization Index, which combines dozens of indicators to provide a comprehensive picture of where and how companies are building digital assets, expanding digital usage, and creating a more digital workforce. In addition to the information- and communication-technology sector, media, financial services, and professional services are surging ahead, while others have significant upside to capture.
