* The territorial units used in
the Russian Empire in 1897 are translated here as follows:
уезд (uyezd) - distriict, губерния (guberniya) - governorate,
градоначальство (gradonachalstvo) - city municipality, военное
губернаторство (voyennoye gubernatorstvo) - military governorate.
The names of cities are translated according the usual dictionaries,
if not found - taken from Wikipedia, if not found in both
sources - transliterated.
** Here the language composition of population is given
for the districts of the Russian Empire. In the census results
the whole set of languages was published, however this DW
page displays only the languages spoken by at least 100
persons of one sex (mainly males) in each governorate. Russian,
Urkanian, and Belorussian are given in all regions.
*** Calculations by Demoscope Weekly
**** The last line "Remainder" is formed from
the languages spoken by the population sized less than 200
at a territory. The census results published have no such
line since all the languages were given including the languages
spoken by only 1 person.
***** This and similar lines refer to the population of
a territory without population of the district's center
if it is not an urban settlement.
