The Public Ministry of the State of Acre (MPAC) clarified, through an official note, that there was a technical error in the data on the number of prisoners in Acre recently released in the violence indicator panel of the Criminal Analysis Observatory of the Technical Support Center (NAT). The failure generated an incorrect reading that indicated a significant increase in the Acre prison population.

According to MPAC, the inconsistency was identified after the publication of the ContilNet article, last Monday (3), entitled “Prison explosion: number of prisoners in Acre shoots up 45% in one year and exceeds 8 thousand”which used information from the aforementioned panel.
SEE THE ARTICLE:
The Observatory’s technical analysis pointed out that the distortion was caused by a failure in the automatic reading of data, caused by changes in the nomenclature of the state’s prison units, implemented from August 2025.
These changes prevented the system from recognizing the new denominations and correctly applying the exclusion routine for electronically monitored prisoners, which resulted in them being unduly counted in the total number of incarcerated people. As a result, the 2025 numbers now include people under monitoring, while previous historical series only considered inmates in physical units, thus generating an artificial variation of around 45%.

MPAC reported that NAT has already corrected the database, reprocessing the information to reestablish the original exclusion criteria for those monitored electronically. The institution confirmed that the supposed increase does not represent reality and that the updated panel already reflects the correct numbers.

In a note, the agency concluded that the discrepancy does not indicate real growth in the prison population, but merely a technical error in reading and compatibility of data, which has already been duly resolved.
Note: MPAC clarifies inconsistency in panel of violence indicators regarding prison staff in Acre
The Public Ministry of the State of Acre (MPAC), through the Criminal Analysis Observatory of the Technical Support Center (NAT), informs that a technical inconsistency was identified in the panel of violence indicators, specifically in the graph called “History of the Prison Staff with the Exception of Those Monitored Electronically – Regarding the Selected Month”.
The inconsistency was discovered after the publication, on November 3, 2025, of an article on the Contilnet portal entitled “Prison explosion: number of prisoners in Acre shoots up 45% in one year and exceeds 8 thousand”, which used data from the aforementioned panel.
The Observatory’s technical analysis pointed out that the distortion resulted from an automatic reading failure generated by changes in the nomenclature of the State’s prison units, implemented from August 2025. These changes prevented the automated routine for excluding those monitored electronically from recognizing the new names, causing the improper inclusion of these cases in the total number of prisoners.
As a consequence, the previous historical series, which only counted people deprived of their liberty in physical units, began to be compared with data from 2025 that also included those monitored electronically, producing an artificial variation of approximately 45% in the total number of people deprived of their liberty.
The Observatory adopted the necessary corrective measures, adjusting the database to recognize the new nomenclatures of prison units and reprocessing the historical series while maintaining the original criteria for excluding those monitored electronically.
In this way, it is clarified that the discrepancy identified does not reflect a real increase in the number of people incarcerated in Acre, but rather a technical error in reading and compatibility of data.
