The social map in Venezuela has remained unchanged over the past 12 years, despite government claims that the number of poor has dropped sharply.
According to research firm Datanálisis, the proportion of social strata is quite similar to that in 1999, and the only difference with respect to that year is that now the poor receive more state subsidies than before.
Luis Vicente León, the managing partner of the consulting firm, said that AB strata include 2.31 percent of the population; 17.6 percent are in the C stratum; 35.9 percent are in D stratum and the E status -which includes the poorest- comprises 44.15 percent of the population.
The lowest stratum grew in the first quarter of this year compared with the level recorded in 1999 (40.8 percent). However, León said that this does not really reflect an increase in the number of poor, as the percentage of variation is within the margin of error that may occur in a study of this type.
