Ndiani akataura kuti Gini coefficient ishandiswe kuyera kusaenzana kwemari kana kuti upfumi?
Context:Mune zveupfumi, Gini coefficient, inozivikanwawo se Gini index kana Gini ratio, chiyero chekupararira kwehuwandu chinomiririra kusaenzana kwemari kana kusaenzana kwehupfumi kana kusaenzana kwekushandisa mukati merudzi kana boka rezvemagariro. Yakagadzirwa nenyanzvi yezvokuverengwa kwevanhu uye nyanzvi yezvemagariro evanhu Corrado Gini. Gini coefficient inoyera kusaenzana pakati pemitengo yekugoverwa kwehuwandu, senge mazinga emari. Gini coefficient ye0 inoratidza kuenzana kwakakwana, uko mari yose kana kuti pfuma inokosha zvakafanana, nepo Gini coefficient ye1 (kana kuti 100%) inoratidza kusaenzana kukuru pakati pezvinokosha. Somuenzaniso, kana munhu wose aine mari yakaenzana, Gini coefficient ichava 0. Mukupesana, coefficient yaGini ye1 inoratidza kuti mukati meboka ravanhu, munhu mumwe chete ane mari yose kana kuti kushandiswa, nepo vamwe vose vasina. Coefficient yaGini yakatangwa naCorrado Gini sechiyero chekusaenzana kwemari kana upfumi. Nokuda kwenyika dzeOECD, mukupera kwezana remakore rechi20, tichifunga nezvemigumisiro yemitero uye kubhadharwa kwemari, mari yeGini coefficient yakabva pakati pe0.24 ne0.49, neSlovenia iri pasi uye Mexico iri pamusoro. Nyika dzemuAfrica ndidzo dzaiva nechiyero chepamusoro-soro chisati chabhadharwa mitero muna 2008<unk>2009, uye South Africa ndiyo yaiva nechiyero chepamusoro-soro pasi rose, chinofungidzirwa kuva pakati pe0.63 kusvika ku0.7, kunyange zvazvo nhamba iyi ichiderera kusvika ku0.52 kana rubatsiro rwemagariro evanhu rwabatanidzwa, uye ichiderera zvakare kusvika ku0.47 kana mutero wapera. Nhamba yemari yepasi rose yeGini muna 2005 yakafungidzirwa kuva pakati pe0.61 ne0.68 nemanyuko akasiyana-siyana.
