Most, however, migrated here voluntarily in the beginning of the 20th century, after the revolutionary events of 1905 and as a result of the agrarian reforms by Pyotr Stolypin.

The second wave of migrants rushed in during the late 1920s, as the area was subject to collectivization on a lesser scale than other regions of the country.

Even after settling in, people continued to speak their native language and maintained their customs and traditions, passing them on to the new generations.

After World War II, many people exiled here started families; many remained to live and work in the district.

In the 1960s, Aban became a destination for people exiled from the big cities under the "Decree of 1961"—people were sent here for their religious beliefs, for drunkenness, and for parasitism.

The villages of Machino, Tagashi, Noshino, and Beryozovka housed Germans who were deported here after the end of World War II.

The deported Germans were required to register with the local commandant twice a month and were prohibited from leaving their assigned residences.

Agriculture and forestry, at 55.6%, comprise the largest share of the district's economy, followed by the wholesale and retail trade and auto maintenance (18%).
