It is one of the few Russian words that begin with Ы. Ytyk-Kyuyol became the administrative center of the newly created Alexeyevsky District in 1930.

An agricultural center, Ytyk-Kyuyol has developed cattle and horse breeding industries; growing of potatoes and other vegetables is also common.

Ytyk-Kyuyol is located on the R504 Kolyma Highway, allowing road access to Yakutsk.
