Curiously, at the early stage of settlement (late 1890s), men in Korsakovsky outnumbered women almost by a factor of ten. In 1897, for example, 1510 males and 192 females lived in the town. This disbalance is explained by the fact that the majority of Korsakov's inhabitants were prisoners and prison-keepers—in both categories males predominated. The district of Korsakovsky (in 1897 covering 66762 verst) was home to 4659 males and 2194 females—a much better proportion (fort excluding).
The town's population stood at its highest (45 thousand) in the late 1980s, whereupon it experienced significant decline as inhabitants fled economic downturn by moving to neighboring Yuzhno-Sakhalinsk or to continental Russia. Evidently, Korsakov's population remains in decline, although no longer as sharp as in the 1990s.
The demographic make-up is primarily ethnic Russian with a large ethnic Korean minority.
