Though many residents commute to work to the capital city Budapest, the largest employers in the town are a manufacturing plant named New MGM Zrt., that produces ball bearings and tapered roller bearing for worldwide OEM customers and dealers, an Interspar grocery store, and the International Christian School of Budapest, a school that serves missionary families, expatriates, and Hungarians.

The northern part of Diósd is located on the Tétényi plateau, which is a natural reserve.

Swabians arrived from Southern Germany to repopulate the town and they were in majority there until the end of the second world war, when many of the Swabes were chased away.

Many of these cellars were made as big as normal houses to fit in the equipment used to make wine.

Since 1989, Diósd works in tight partnership with the German town Alsbach-Hähnlein in Hesse.

The opposite direction of this road leads to Budapest, where most of the residents of Diósd work.

Diósd also has an exit on the M0 highway which opened in 1994 and runs on the northern and eastern edge of the town.
