Mytishchi is one of the most populated cities in Moscow Oblast, with the 2021 census recording a population of approximately 255,429 residents. The city has experienced rapid and sustained population growth over the past two decades, largely driven by internal migration from other parts of Russia and families moving out of central Moscow in search of more affordable, modern housing.
The demographic makeup is predominantly ethnic Russian, with visible minorities from neighboring former Soviet republics (such as Armenia, Belarus, Ukraine, and nations in Central Asia) contributing to the local workforce and cultural tapestry. The dominant religion is Russian Orthodox Christianity.
Mytishchi boasts a highly educated population. Due to its status as a commuter hub for Moscow, a significant percentage of its residents hold university degrees and work in specialized technical, managerial, or administrative roles in the capital, commuting daily via rail or highway.
