I-Gini coefficient ilinganiselani?
Context:Kwezomnotho, i- Gini coefficient, eyaziwa nangokuthi i- Gini index noma i- Gini ratio, iyindlela yokusabalalisa kwezibalo okuhloswe ngayo ukumela ukungalingani kwemali engenayo noma ukungalingani kwengcebo noma ukungalingani kokusetshenziswa ngaphakathi kwesizwe noma iqembu lomphakathi. Yasungulwa isazi sezibalo nesazi sezenhlalo uCorrado Gini. I-Gini coefficient ilinganisa ukungalingani phakathi kwamanani okusabalalisa imvamisa, njengamazinga omholo. Isilinganiso sikaGini esingu-0 sibonisa ukulingana okuphelele, lapho yonke imali engenayo noma amagugu omcebo efana khona, kuyilapho isilinganiso sikaGini esingu-1 (noma u-100%) sibonisa ukungalingani okukhulu phakathi kwamagugu. Ngokwesibonelo, uma wonke umuntu enomholo ofanayo, i-Gini coefficient iyoba u-0. Ngokuphambene, i-Gini coefficient engu - 1 ibonisa ukuthi eqenjini labantu, umuntu oyedwa unakho konke imali engenayo noma ukusetshenziswa kwayo, kuyilapho bonke abanye bengenayo. I-Gini coefficient yasungulwa uCorrado Gini njengesilinganiso sokungalingani kwemali engenayo noma ingcebo. Emazweni e-OECD, ngasekupheleni kwekhulu lama-20, uma kucatshangelwa umphumela wentela nokukhokhwa kokudluliselwa kwemali, isilinganiso semali engenayo kaGini sasiphakathi kuka-0.24 no-0.49, iSlovenia iyona ephansi kakhulu neMexico iyona ephakeme kakhulu. Amazwe ase-Afrika ayenama-pre-tax Gini coefficients aphakeme kakhulu ngo-2008<unk>2009, neNingizimu Afrika enamazwe aphakeme kunawo wonke emhlabeni, alinganiselwa ku-0.63 kuya ku-0.7, yize lesi sibalo sehle saba ngu-0.52 ngemuva kokubhekelela usizo lwezenhlalakahle, futhi sehle futhi saba ngu-0.47 ngemuva kokukhokha intela. Isilinganiso semali engenayo yomhlaba wonke ngo-2005 kulinganiselwa ukuthi siphakathi kuka-0.61 no-0.68 ngemithombo ehlukahlukene.
