Wealth is especially concentrated in the northern states bordering the United States, especially in the eastern part bordering Texas, and in the south part of Gulf of Mexico (Campeche and Tabasco). States in the south Pacific coast (e.g. Chiapas, Oaxaca, and Guerrero) are the most stricken by poverty. Of the seven fastest growing states over the same time period, two are found in the bottom quartile (Nayarit and Zacatecas), three in the second-lowest quartile (Hidalgo, Veracruz and San Luis Potosi), and only two in the top quartile (Campeche and Tabasco) of GDP per capita.
