After decades of fretting about population explosion, scientists are pointing to a long-term hidden global menace.

The household. More specifically, the household explosion.

In this week’s Early Online edition of Population and Environment, Jianguo “Jack” Liu, director of the Michigan State University Center for Systems Integration and Sustainability, and former students Mason Bradbury and Nils Peterson present the first long-term historical look at global shifts in how people live. One large household sheltering many people is giving way across the world to households comprised of fewer people – sometimes young singles, sometimes empty nesters, and sometimes just folks more enamored with privacy.

In the late 1960s, ecologist Paul Ehrlich of Stanford University sounded the alarm about population growth. Now, Liu and his colleagues are pointing out that even though population growth has been curbed, the propensity to live in smaller households is ratcheting up the impact on the natural resources and the environment worldwide.

“Long-term dynamics in human population size as well as their causes and impacts have been well documented,” said Liu, who is the Rachel Carson Chair in Sustainability. “But little attention has been paid to long-term trends in the numbers of households, even though households are basic consumption units.”
