The U.S. is becoming more of a nation of immigrants every day—just as it was, but in very different ways, a century ago.

The share of immigrants in the U.S. population rose last year to 13.1%, from 13% in 2012—the highest level since the 1920s. As the Journal reported Friday, immigration is picking up as the U.S. economy improves, driven largely by Asian newcomers but also by a sizeable gain in Hispanic (including Mexican) arrivals. If these trends gain traction, the U.S.’s share of foreign-born is likely to keep climbing, extending a spectacular rise from just 4.7% in 1970.

But will the U.S. again become as immigrant-centered as it was at the dawn of the 20th century?
