Income share held by highest 10% SI.DST.10TH.10
Guinea-Bissau's income share top 10% was 26.10% in 2021, ranked 35th globally. This represents a 5.4% decrease from 2020. Data from World Bank, covering 1991–2021.
Overview
Guinea-Bissau's income share top 10% stood at 26.10% in 2021, a decline of +1.50pp from 2018. Guinea-Bissau ranked 35th globally.
Guinea‑Bissau’s share of income accruing to the top 10 percent of earners fell from an all‑time peak of 42.20 % in 1991 to a trough of 26.10 % in 2021, placing the country 35th globally in the latest World Bank series. This 16.10‑percentage‑point decline, observed over the six years for which data are available, signals a marked reduction in income concentration relative to the early 1990s. By contrast, peer economies such as Serbia (25.90 %) and Georgia (26.20 %) exhibit comparable top‑decile shares, suggesting that Guinea‑Bissau’s current distribution aligns with the lower end of the regional spectrum. The downward trajectory reflects gradual improvements in fiscal redistribution and modest growth among lower‑income groups, yet the persistence of a quarter of total income within the richest decile indicates limited inclusive growth. Continued reforms in tax policy, social protection and productive sector development could deepen the decline in top‑10 % share and foster a more equitable income distribution in the coming decade.
