In 2025, 15.6% of people who carried out a bureaucratic procedure (trámite), made a payment to a government office, requested a public service or had any other kind of contact with authorities experienced an “act of corruption,” according to the results of the latest National Survey of Governmental Quality and Impact (ENCIG).
The national statistics agency INEGI conducted the survey at 46,000 homes in late 2025 and the results were published in May.
In this “Mexico in Numbers” article, we look at where in Mexico people are most and least likely to encounter corruption when interacting with municipal, state and federal authorities. One of the main ways people experience corruption in Mexico is by being asked to pay a bribe.
We also present survey results on:
- The situations in which corruption directly affecting citizens is most prevalent.
- The institutions that are considered the most and least corrupt.

The state where people most commonly experience corruption is Hidalgo. Around 21.5% of residents from that state who came into contact with authorities last year experienced an act of corruption, according to the ENCIG results.
