The baby boom after World War II affected American social life and several experts discuss the impact of the coming “diversity boom”:

“This new diversity boom that we’re seeing right now will be every bit as important for our country in the decades ahead as the baby boom [people born between 1946 and 1964] was in the last half of the 20th century,” said demographer William Frey of the Brookings Institution.

“We know that the baby boom has changed the country in lots of ways – popular culture, changing values about all kinds of social issues, families, women’s roles and politics.  And I think this diversity boom is going to have just as big of an impact.  We’ll be a very different country and we’re only just beginning to see the start of it,” said Frey…

“The degree of cultural diversity that this introduces to this country is rather like the cultural diversity we had in the 19th century, and for that matter in the 18th century at the time of founding,” observed American Enterprise Institute political scientist Charles Murray.  In many ways, according to Murray, diversity has been a positive force throughout America history…

A few decades ago, many analysts warned that these demographic trends would lead to a balkanization of America.  However, most experts now agree that U.S. culture and assimilation will reinforce America’s national character, particularly as the rate of interracial marriage grows.

Demographics or geographic mobility may seem fairly dull but sizable changes – here, an increase in immigration and the foreign-born population or a significant increase in birth rates in the postwar era – are influential. It is interesting to see the positive responses from the experts cited here as I’m less confident that such optimism would be shared by a big majority of Americans. Additionally, such booms don’t last forever (or statistically they may just cease to be booms) though it would be hard to predict when this current boom would slow.
