Mount Union was largely influenced by industry. It was at one time the world's largest producer of refractory material (silica brick), with three plants – General Refractories, United States Refractories, and Harbison Walker. The refractory business in Mount Union lasted from 1899 to about 1972, with limited production into the early 1990s. Other industries included two tanneries, a tanning extract plant, coal yards, an explosives and munitions plant (Aetna), and foundry and machine shops.

Mount Union was the northern terminus for the narrow gauge East Broad Top Railroad, connecting to the Main Line of the Middle Division of the Pennsylvania Railroad (now Norfolk Southern). The EBT maintained a large dual-gauge yard and coal cleaning plant in Mount Union and supplied coal to the Refractory plants. The EBT ceased operations in 1956 but the track is still in place and owned by the railroad. From 1998 to 2010, the Mount Union Connecting Railroad attempted to reactivate the EBT main track through Mount Union and rehabilitated it, but only a couple cars were serviced and none moved over the EBT trackage.

The Mount Union Historic District was listed on the National Register of Historic Places in 1994, with 300 significant historic structures, buildings, and homes.^[4] The population tally in 1900 was 1,086 which rose to 3,338 in 1910.

The culturally significant Thousand Steps of the Standing Stone Trail are located in the Jacks Narrows, approximately two miles west of the town along U.S. Route 22. The annual Creation Festival was hosted locally (in Shirleysburg) from 1984 to 2022, drawing thousands of visitors in late June.^[5] Mount Union is the site of the Pennsylvania Lions Beacon Lodge Camp, a summer camp for people with visual impairments and special needs, founded by Carl Shoemaker in 1948.^[6]

According to the United States Census Bureau, the borough has a total area of 1.2 square miles (3.1 km²), of which 1.1 square miles (2.8 km²) is land and 0.04 square miles (0.10 km²) (2.59%) is water.
