An uchastok (Russian: yча́сток) or police prefecture (полицейский участок) was a territorial-administrative unit of the Russian Empire and early Russian SFSR. Throughout most of modern Russian history, uchastoks, which numbered 2,523 throughout the empire by 1914, were a third-level administrative division, below okrugs, uezd and otdels (counties). In a literal sense, uchastok approximately corresponds to the English term plot, however, in practical usage it corresponded to a municipal district.[1]
