Sotsial'noe neravenstvo i kolichestvennye pokazateli egotema aktual'naya i vsegda vyzyvayushchaya obshchestvennyy interes. V osnove matematicheskogo modelirovaniya sotsial'noekonomicheskoy struktury obshchestva lezhit funktsiya Lorentsa. Znachenie funktsii est' dolya vsego obshchestvennogo bogatstva, kotoraya summarno prinadlezhit samym bednym chlenam obshchestva, summarno sostavlyayushchim dolyuargument vsego obshchestva. Ponyatie srednego klassa vvedeno v 2003 g. V.I.Malykhinym: v obshchestve est' sredniy klass, esli sredinnaya chast' obshchestva (ot 1/4 do 3/4) vladeet ne menee polovinoy obshchestvennogo bogatstva. V 2009 g. P.S.Gevorkyan i Malykhin dokazali teoremu: esli v obshchestve est' sredniy klass, to koeffitsient (indeks) Dzhini ne bol'she 1/4. Eta teorema imeet fundamental'nyy kharakter ona pokazyvaet, chto deystvitel'no sredniy klass pridaet obshchestvu stabil'nost', ustoychivost' k sotsial'nym potryaseniyam, ne dopuskaet sil'nogo sotsial'nogo neravenstva. V monografii polucheny i drugie neravenstva dlya pokazateley sotsial'noy differentsiatsii, naprimer, neravenstvo mezhdu indeksami Dzhini i Guvera. Monografiya napisana prosto, ponyatno studentam mladshikh kursov Vuzov i kolledzhey.
