Pete Bell's TeleGeography data (below) show 10% growth at Argentina, Guatemala, Ecuador, Costa Rica, and El Salvador. Puerto Rico and Venezuela actually lost subscribers. Brazil added 2,083,000 to 28,670,000 (7.8% growth.) Telefónica Vivo is rushing to 10M homes with FTTH in order to win market share.

Uruguay has 79% household penetration. Government-owned Antel has covered 82% of the country with fiber home. Chile and Mexico are far behind at 61% and 59%. Brazil is at 43%. I don't have data, but I'd bet San Paulo and the Southern part of Brazil are closer to 60% and the North much lower. Brazil has extreme income and racial inequality with a Gini coefficient of 50. (The U.S. is the most unequal of developed countries, at 40; France is 32.)
