Opposition lawmakers criticized Mexico's independent statistics agency on Tuesday for changes in polling techniques in a survey that suggested income among the poorest Mexicans had jumped by a third.
Lawmakers said the survey, published on July 15, created suspicions that pollsters had manipulated data in order to show a drop in poverty after a previous study had shown poverty increased in Mexico in 2014.
"The credibility of an institution so important as (statistics agency) INEGI is in doubt," said Senator Ernesto Cordero, a former finance minister from the conservative National Action Party (PAN).
The survey sparked a scandal in . . .
