The Census Bureau reported on Dec. 20 that America’s population grew 0.7 percent from July 1, 2015 to July 1, 2016 — the slowest rate of increase since the Great Depression. In some sense, this is neither good news nor bad news, just a reflection of demographic trends.
But demographic trends can have big implications. As a general rule, businesses like the idea of more people for the simple reason that they will have more customers.



An expanding population is particularly important for certain sectors of the economy, such as housing. So there is a general assumption that a nation with a growing population will have more economic output.
Though, what presumably matters most is not total economic output, but rather per-capita output. People sometimes get agitated, for instance, that China’s gross domestic product (GDP) eventually may exceed GDP in the United States.
