Here is how fast America is changing: By the time today’s teenagers hit their 30s, there will be — for the first time ever — more minorities than whites, more old people than children, and more people practicing Islam than Judaism. 

The big picture: The slow demographic shifts we've watched over decades will finally reach a tipping point in the 2040s. They'll transform what America looks like, where we live and what we fear.

What we will look like

We'll be older and less white in the 2040s.

  • Only 45% of 30-year-olds will be non-Hispanic whites in 2040. And minorities will become the majority in the U.S. by 2045, according to Census projections.
  • There will be more old people than children for the first time because of the falling fertility rates, the Census data shows. More than 1 in 5 Americans will be over the age of 65, putting a new level of stress on the nation's Social Security and health care systems.
  • Immigrants will make up a record-breaking share of the population and will have a crucial role in carrying the economic load created by the elderly Boomers and Gen X-ers.
