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. The ground has a very high concentration of limestone, and many uncommon plants can be found in this area. At least two Beehive Stones can be found in the forest in the northwest of Diósd. Two former limestone quarries also exist where locals often like to meet.
Diósd was first mentioned in 1417 under king Sigismund.
Diósd is known in German by the name Orasch. The reason for this phenomenon is that after the Turkish invasion, the area was fully uninhabited. 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. The Swabians in Diósd usually lived from making wine in wine cellars. Many of these cellars were made as big as normal houses to fit in the equipment used to make wine. Some of the wine cellars were longer than 100 meters. In the 1880s most of the vineyards were killed by Phylloxera. Since the cellars and storage houses became useless, they were converted into new residential houses. Most of these are still inhabited. Since most cellars still exist and many are located under the roads of the town, weight restrictions have to be taken seriously. After the vineyards died, the residentials planted plums. Almost all of these were finally destroyed in the 2000s when many new houses were built on the location of the plum fields.
At the beginning of the 20th century Diósd was part of the Fejér county.
Until 1994, a radio station with many antennas existed in the northern part of Diósd. Radio broadcasting had to be stopped because the M0 highway was built near the area. Today, only one antenna remains, and the radio station has been transformed into a radio and television museum.
Since the 1990s, many new houses were built in the town since people wanted to move near Budapest. Because of this, the house numbers had to be reordered by the managegent of the town. They were however not successful, and today many houses have two or three house numbers which lead to confusion of non-local people.
Diósd officially became a city on July 15, 2013.
The national road 7 runs through Diósd. It is known by locals as the "Balatoni út" (Balaton street) since if you travel on it, you eventually get to the lake Balaton. The opposite direction of this road leads to Budapest, where most of the residents of Diósd work. Budapest can also be reached by Bus from Diósd.
Diósd also has an exit on the M0 highway which opened in 1994 and runs on the northern and eastern edge of the town.
