The growth of population in the Republic after 1970 is in no small part due to the construction of a number of large hydro and thermal power, petrochemical, and automotive facilities in Zainsk, Nizhnekamsk, and Shorey Chelny and the attraction of labor from many other regions. This indicator is also influenced in recent years by migration of population.</p>Kazan Medical archiveКазанский медицинский архив
