An anonymous reader writes: Diversifying the tech industry is a prominent topic these days, with much analysis being done on colleges and companies that employ software engineers. But exam data shows the gap is created much earlier — it's almost overwhelming even before kids get out of high school. From the article: 'Ericson's analysis of the data shows that in 2013, 18 percent of the students who took the exam were women. Eight percent were Hispanic, and four percent were African-American. In contrast, Latinos make up 22 percent of the school-age population in the U.S.; African-Americans make up 14 percent. (I don't need to tell you that women make up about half.) There are some states where not a single member of one of these groups took the test last year. No women in Mississippi or Montana took it. Seven states had no Hispanic students take the exam: Alaska, Idaho, Kansas, Mississippi, Montana, Nebraska, and North Dakota. And 10 states had no Black students take the exam: Alaska, Idaho, Kansas, Maine, Mississippi, Montana, Nebraska, New Mexico, North Dakota, and Utah. In some of these states, there simply aren't many students of any race or gender taking the test, which helps explain the dearth of young women and minorities. (Indeed, no women or minorities took the exam in Wyoming—but that's because no students at all took it.) But Idaho had nearly 50 students taking it, and Utah had more than 100.'
