In 1850 – nine years before the Carrington Event and 12 years before the Civil War – the population of the United States was 23 million people. At the end of 2018, the population of the U.S. had reached 328 million people. What enabled the population to increase by 305 million people is quite simple: technology. New technologies that promoted this growth include: advances in medicine, advances in agricultural methods, the ability to transport food across the country (and across the world), new sources and uses of energy, an industrial revolution, advances in many areas of technology, and so on. All of these technologies are tied to one significant event: the advent of the electric grid.
