Po popisu iz 2001. godine otok ima 19 stalnih stanovnika, od kojih je 8 starije od 65 godina. Još 1961. je na Biševu bilo 114 stanovnika ( prije Drugog svjetskog rata preko 200 ), koji su se preselili uglavnom u Komižu. Mnogi su i dalje ostali vezani za svoj otok na kojem obrađuju vinograde i maslinike, a ljeti uglavnom i borave na njemu.                           (http://hr.wikipedia.org/wiki/Bi%C5%A1evo)
