'''Koefisien Gini''' adalah ukuran yang dikembangkan oleh statistikus [[Italia]], [[Corrado Gini]], dan dipublikasikan pada tahun 1912 dalam karyanya, ''Variabilità e mutabilità''.

[[Koefisien]] ini biasanya digunakan untuk mengukur kesenjangan pendapatan dan kekayaan. Di seluruh dunia, koefisien bervariasi dari 0.25 ([[Denmark]]) hingga 0.70 ([[Namibia]]).

Koefisien gini memiliki [[indeks]] yang memiliki rentang nilai antara 0 sampai dengan 1. Nilai 0 berarti tidak ada kesenjangan ekonomi, atau perekonomian merata pada daerah tersebut. Sementara itu, nilai 1 menunjukkan nilai kesenjangan maksimal.<ref>{{Cite web|title=Tingkat Ketimpangan (Indeks Gini) - Pojok Ekonomi|url=https://pojokperekonomian.grobogan.go.id/info-ekonomi/ekonomi-regional-grobogan/232-tingkat-ketimpangan-indeks-gini-2|website=pojokperekonomian.grobogan.go.id|access-date=2021-06-16}}</ref>
