The municipality of Miguel Auza is located at an elevation between 1,800 and 2,600 metres (5,900–8,500 ft) on the Mexican Plateau in northern Zacatecas.

In 1935, the municipality was renamed in honour of General Miguel Auza Arrenechea (1822–1892), who was born in Sombrerete and fought in the Reform War and at the 1863 Siege of Puebla.

[7][8] The municipal government of Miguel Auza comprises a president, a councillor (Spanish: síndico), and thirteen trustees (regidores), eight elected by relative majority and five by proportional representation.

The main crops grown are beans and alfalfa, Miguel Auza being located in Mexico's most important bean-growing region.

[6] Miguel Auza also has a facility that processes silver, lead and zinc ore obtained from the Platosa mine in Durango.
