Although multiple international organizations coincide and classify Mexico as an upper middle income country, or a middle class country  Mexico's National Council for the Evaluation of Social Development Policy (CONEVAL), which is the organization in charge to measure the country's poverty reports that a huge percentage of Mexico's population lives in poverty. According to said council, from 2006 to 2010 (year on which the CONEVAL published its first nationwide report of poverty) the portion of Mexicans who live in poverty rose from 18%–19% to 46% (52 million people). However, rather than Mexico's economy crashing, international economists attribute the huge increase in the percentage of population living below the country's poverty line to the CONEVAL using new standards to define it, as now besides people who lives below the economic welfare line, people who lacks at least one "social need" such as complete education, access to healthcare, access to regular food, housing services and goods, social security etc. were considered to be living in poverty (several countries do collect information regarding the persistence of said vulnerabilities on their population, but Mexico is the only one that classifies people lacking one or more of those needs as living below its national poverty line). Said economists do point out that the percentage of people living in poverty according to Mexico's national poverty line is around 40 times higher than the one reported by the World Bank's international poverty line (with said difference being the biggest in the world) and ponder if it would not be better for countries in the situation of Mexico to adopt internationalized standards to measure poverty so the numbers obtained could be used to make accurate international comparisons. According to the OECD's own poverty line (defined as the percentage of a country's population who earns 60% or less of the national median income) 20% of Mexico's population lives in a situation of poverty.
