How did we come by the “leading indicators” we place such stock in? We allocate trillions of dollars and make public
policy and personal decisions based upon them, but what do they really tell us?
We are bombarded every day with numbers that tell us how we are doing, whether the economy is growing or shrinking,
whether the future looks bright or dim. Gross national product, balance of trade, unemployment, inflation, and consumer
confidence guide our actions, yet few of us know where these numbers come from, what they mean, or why they rule our
In The Leading Indicators, Zachary Karabell tells the fascinating history of these indicators. They were invented in the
mid-twentieth century to address the urgent challenges of the Great Depression, World War II, and the Cold War. They
were rough measures— designed to give clarity in a data-parched world that was made up of centralized, industrial
nations—yet we still rely on them today.
We live in a world shaped by information technology and the borderless flow of capital and goods. When we follow a 1950s
road map for a twenty-first-century world, we shouldn’t be surprised if we get lost.
What is urgently needed, Karabell makes clear, is not that we invent a new set of numbers but that we tap into the
thriving data revolution, which offers unparalleled access to the information we need. Companies should not base their
business plans on GDP projections; individuals should not decide whether to buy a home or get a degree based on the
national unemployment rate. If you want to buy a home, look for a job, start a company, or run a business, you should
find your own indicators. National housing figures don’t matter; local ones do. You can find them at the click of a
button. Personal, made-to-order indicators will meet our needs today, and the revolution is well underway. We need only
to join it.
