Chula Vista Quarry se ubica en San Diego County, California, donde la categoría minera del Censo representa el 0.0% del empleo del condado.
ⓘ
Las cifras del condado provienen de la Encuesta sobre la Comunidad Estadounidense de la Oficina del Censo de EE. UU., estimaciones quinquenales agrupadas, por lo que la edición de 2023 abarca de 2019 a 2023. La categoría del Censo es 'minería, explotación de canteras y extracción de petróleo y gas', que es más amplia que la jurisdicción de la MSHA e incluye a trabajadores de petróleo y gas que ninguna mina emplea. Estas cifras describen el condado circundante, no esta mina, y no son un factor en ningún incidente específico.ⓘ
