Analysis
NAICS 212313 is the 2022 national industry for crushed and broken granite mining and quarrying, part of 21231 (Stone Mining and Quarrying). Census lists 7 example activities under it in the official index.
Between 2018 and 2023 the number of establishments fell 17% and employment fell 7%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
County Business Patterns counts 251 US establishments in this code in 2023, employing 5,670 people at an average annual payroll of $86,271 per employee (74th percentile of national industries). 16% of the establishments have fewer than five employees, which points to larger operations.
By establishments it ranks 4th of the 4 codes at this level within Stone Mining and Quarrying, with 10.3% of them.
