For many years, the U.S. measured literacy simply by asking respondents whether they could read or write, an approach perhaps sufficiently adequate when most people worked with their hands. Using this method, the Census Bureau in 1969 estimated that illiteracy in the U.S. population age 14 and older was only 1 percent.

In 1992 the U.S. Department of Education embarked on a more thorough analysis and mounted a landmark survey. It asked a representative group of 26,091 Americans to read several texts and then had them demonstrate that they understood the texts. The department used three types--prose, document and quantitative texts--containing fairly simple material encountered in everyday life. The study was repeated in 2003.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
