Demographic changes in student populations
The demographic makeup of the United States' student population has changed since the first long-term trend reading assessment was administered in 1971.
- At age 9, the proportion of Hispanic students has increased from 5 percent in 1975 to 27 percent in 2025, while the proportion of White students has decreased from 80 percent to 48 percent over the same time period.
- Another notable change is that a higher percentage of 9-year-old students are now in a grade lower than the one typical for their age: 24 percent of 9-year-olds were in a grade lower than fourth grade in 1971, whereas 39 percent of 9-year-old students were below their typical grade in 2025.
- The proportion of 9-year-olds in grade 4 has decreased from 75 percent to 61 percent over the same time period.
