More than 2,300 Americans died in the attack at Pearl Harbor exactly 72 years ago on Saturday. The USS Arizona was destroyed, the USS Oklahoma overturned. As a result, Congress ushered the nation into the second world war.

More than 16 million Americans served in that war, and more than 400,000 died. And nearly 1.6 million World War II veterans are still alive, according to Census data. Earlier in the year, we took a look at the veteran population in each state and found that those who served in World War II make up a larger share of the total veteran population in the northeast than in any other region. Here’s what we wrote about the data then:

In Connecticut, World War II veterans make up a larger share of the total veteran population than in any other state, with those older veterans making up 11.5 percent of the total veteran population. Massachusetts, New York, Rhode Island and New Jersey are home to the next four largest WWII veteran populations, as a share of the total. In each of the five states, one in 10 veterans served in WWII. Alaska, which didn’t become a state until after WWII ended, has the smallest share of WWII veterans, followed by Georgia where fewer than one in 20 veterans is a WWII vet.
