Not everyone agrees that demographics are destiny. But demographic trends are key drivers of change and also one of the few things we can project into the future with decent accuracy.
Pew Research's 7 demographic trends shaping the U.S. and the world in 2018 looks at the demographic trends Pew considers to be the most important.
Our favorites are:
Millennials are projected to outnumber Baby Boomers next year: Numbering 71 million in 2016, Millennials in the United States are approaching Baby Boomers (74 million) in population and are projected to surpass them as the nation’s largest living adult generation in 2019.
A record number of Americans live in multigenerational households, part of a broader trend toward more shared living. In 2016, a record 64 million people, or 20% of the U.S. population, lived with multiple generations under one roof …
The institution of marriage continues to change. Half of U.S. adults today are married, a share that has remained relatively stable in recent years but is down significantly over previous decades. Cohabitation among unmarried partners is rising, including among a growing share of unmarried parents.
After decades of decline, motherhood and family size are ticking up in the U.S. Among women at the end of their childbearing years (ages 40 to 44), 86% had ever given birth by 2016, an increase from 80% in 2006 and about the same share as in the early 1990s. Women also are having more children: On average, women in 2016 had 2.07 children during their lives – up from 1.86 in 2006, the lowest average on record.
These are our favorites because they impact a wide range of social and business activities.
See the Pew article for more details.
Also, The Atlantic's The Age of 'Shotgun Cohabitation' nicely covers the growing trend of unmarried parents living together with their children.
