The highest figures correspond to the northern, north-eastern and central-western regions of the country. The settlement of these areas, especially the zones along the southern and eastern borders of the Amazon jungle, is quite recent, and the production of agricultural commodities for export in these areas is steadily increasing, but the cities in these zones are still not fully developed. The variables associated with the greatest deprivation have to do with urban services (running water, sewerage systems and systems for the disposal of household waste, etc.).
