More than 85,000 families are participating in Texas' private school voucher program during its first year, a number that could increase as state officials finalize enrollment data, according to a new state report.

White families make up most of the participants so far, as do those considered low-income, the comptroller's office noted in the report released Monday.

The report did not say how many students previously attended private school or received home schooling, although earlier data showed that 57% of families invited to the program fell into that category.
