Samuel Villavicencio sent me a spreadsheet with data for the sectors of Guinea-Bissau. His main source was the
U.N.
Statistics Division 
(retrieved 2009-09-29). This information led me to change the spelling of
a few sector names, and add the change history. Bissau is listed here as a sector, and also as an autonomous sector on the
Regions of Guinea-Bissau page. Bissau is divided into sectors numbered 1-8, but I don't count them as
being on a par with the named sectors. Sorin Cosoveanu pitched in with
Guiné-Bissau em
Números (Guinea-Bissau in Figures, retrieved 2009-09-29), an online publication of Instituto
Nacional de Estatística e Censos dated 2005-09-30, which has area data by sector.
