"Just under a fifth of respondents — 19.5 percent — reported cheating in high school. The wealthiest students reported the highest rates of cheating, with 25.2 percent of students with families making more than $500,000 a year having engaged in academic dishonesty. "

The actual base rate of academic dishonesty is unknown. Maybe these students are especially honest about their dishonesty?
