D-Day? What’s That?

As people all over the world observe the 70th anniversary of the Allied invasion of Normandy – widely considered the turning point of World War II – some commenters have expressed concern that the passing of the generation that fought the war means people are at risk of forgetting the importance of that titanic struggle.

If so, that would be nothing new, according to data archived at the Roper Center for Public Opinion Research at Cornell University.

Public knowledge of D-Day was already waning 20 years ago, despite saturation-level media coverage of the invasion’s 50th anniversary and a large number of living D-Day veterans, according to a CBS News poll archived at the Center. When asked “As far as you know, what does the term ‘D-Day’ refer to?,” only 27% gave the correct answer, 29% responded they did not know or offered no answer, and 44% gave an incorrect response. Among those who answered incorrectly, the most frequent response was that D-Day was the day the U.S. won the war or the day the war was over. Another 10% thought D-Day was the day Japan bombed Pearl Harbor. Another 7% linked D-Day to the U.S. bombing Japan or dropping the atomic bomb on that nation.

“We’re a country that makes a point of honoring our veterans, but it seems we’re not always clear exactly what we’re honoring them for,” said Paul Herrnson, Director of the Roper Center and a political science professor at UConn.

Americans did a little better 10 years later, when provided with the prompt that D-Day involved an invasion by the Allies during World War II. Gallup surveys archived at the center showed that in 2004, roughly 60% of Americans were able to identify Germany as the adversary on that day, and France/Normandy/Omaha Beach as the location of the fighting (Figure 2).

In their analysis, Gallup found that the WWII generation and their children, aged 50 and over at the time, were more likely to give an accurate response to these two questions (approximately 70%) than were young adults (40-50%).

However, education was a much better correlate of an accurate perception of D-Day than age, with only 16-17% of college graduates either not knowing or mistaken in their perceptions of where the Allied landing occurred or who the Allies were fighting that day, compared to 48-49% of respondents with only a high school degree (Figure 3).

A lack of accurate knowledge about D-Day isn’t restricted to the U.S. population. A poll taken by FirstNews, a British online weekly for young adults, on May 21st, 2014, shows that 38% of its readers believed D-Day was either during WWI (16%) or the Iraq War (22%).

Age also plays a role in Britain. A survey of 18-35 year olds commissioned by Universal Pictures in support of the Royal British Legion showed that just over half (52%) knew that D-Day marks the day of the Normandy landings, with over a fifth (22%) suggesting that it marks the end of the Great War (The Courier, 5/16/2014). These results are very similar to Gallup’s findings for this age group in the U.S. in 2004.

“There will be ceremonies and speeches to commemorate the anniversary of D-Day this week, and as we pause to mark the occasion, it’s worth stopping to ask how well we’re keeping the memory of those events alive,” Herrnson said.
