Nearly six in 10 Mexicans believe their country's economy went downhill over the last 12 months and few are confident things will get better next year, the polling firm Parametria said.

The company released the results of a study based on 12,800 interviews carried out in person between June 14-28 in every Mexican state. The margin of error is plus/minus 0.9 percent.

The survey shows that 53 percent of Mexicans consider that their personal financial situation got worse during the last 12 months and only 36 percent expect to experience an improvement over the next year.

Parametria said that interviewees had much the same opinion about the national economy, with 56 percent saying it has deteriorated and only 33 percent confident that it will perform better next year.

Perception of where the economy is going differs somewhat by states, for while 44 percent in Baja California, on the U.S. Border, consider that their economic situation improved over the past year, 67 percent of interviewees in the southern state of Guerrero said theirs got worse.

The polling firm said that the darkest outlook of all was in the central state of Hidalgo, where a mere 5 percent saw any improvement, while 70 percent said that their personal economy took a hit.

The national economy polled even worse in Hidalgo, where a whopping 75 percent said that it had plummeted over the past year.

Baja California Sur went against the tide, however, and was the only state where more than half the population saw Mexico's economy on the rise.

Looking ahead to Mexico's 2012 presidential election, Parametria said pocketbook issues are likely to be paramount for many voters.
