In El Salvador, Guatemala and Mexico self-employment income dropped, and wages and salaries increased, while in Uruguay the opposite occurred. In Costa Rica, El Salvador, Honduras and Uruguay, transfers accounted for over 50% of the increase in total income. In countries that saw their poverty reduced the most, such as Brazil, Chile, Ecuador and Panama, transfers accounted for about 20% of the increase in total income. It is not possible in every case to determine from available data exacdy which types of transfers resulted in income increases, because surveys taken around 1990 tended to capture aggregate data.
