Among the OECD countries, Mexico has the second-highest degree of economic disparity between the extremely poor and extremely rich, after Chile – although it has been falling over the last decade, being one of few countries in which this is the case. The bottom ten percent in the income hierarchy disposes of 1.36% of the country's resources, whereas the upper ten percent dispose of almost 36%. The OECD also notes that Mexico's budgeted expenses for poverty alleviation and social development is only about a third of the OECD average. This is also reflected by the fact that infant mortality in Mexico is three times higher than the average among OECD nations whereas its literacy levels are in the median range of OECD nations. Nevertheless, according to Goldman Sachs, by 2050 Mexico will have the 5th largest economy in the world. According to a 2008 UN report the average income in a typical urbanized area of Mexico was $26,654, while the average income in rural areas just miles away was only $8,403. Daily minimum wages are set annually being set at $102.68 Mexican pesos (US$5.40) in 2019. All of the indices of social development for the Mexican Indigenous population are considerably lower than the national average, which is motive of concern for the government.
