It is governed by a city council and a mayor. The current mayor of Bonyhád is Arpad Potapi who has served in this capacity since 2002.
The town's ethnic composition includes Hungarians, Germans, Szekely and Roma. In the years leading to World War II, Bonyhád had a sizable Jewish population. In 1941, Jews constituted approximately 14% of the total population. The community was divided between Orthodox and Reform traditions and Aaron Pressburger was the chief Orthodox rabbi. After the occupation of Hungary by the German army in March 1944, Jews were isolated and their property was confiscated. In May 1944, the Jewish population was estimated at around 1,300. In June 1944, the Jewish communities of Bonyhád and surrounding villages were moved to the two ghettos in Bonyhád and in July 1944, these communities were deported to Auschwitz. In October 1944, approximately 1,200 Jewish labor servicemen were massacred by the SS in Bonyhád. While efforts were made to reestablish the two Jewish communities after the war, there were only 4 Jewish families left in the town by 1963. 
Bonyhád is home to the Völgység Museum. The town's population is served by a Roman Catholic church and a Lutheran church. The remains of the town's two Synagogues are still visible. Various sporting facilities and three high school/college compounds along with the City Hospital currently serve the residents. Telephone service is provided by Bonicom Kft. Gas service is provided by Futomu Kft and water by Vizmu Reszleg.
