Mexico’s National Institute of Statistics and Geography (INEGI) reported that federal and state prosecution agencies opened 2,064,775 investigation files in 2025, in results released on October 1, 2026. The count was 3.5% below 2024. The federal Attorney General’s Office (FGR) reported 84,144 new files and the state prosecution offices (FGE) reported 1,980,631. The federal share was 4.1% and the state share 95.9%. These figures describe administrative workload recorded by prosecution institutions. They are not counts of court cases, verified criminal incidents or people convicted, and the distinction matters when interpreting a census of agency activity.

The opened files contained 2,102,812 recorded offenses, 4.5% fewer than in 2024, according to INEGI. An investigation file may contain more than one offense, so offense records and file openings are different measures. The institute said 98.5% of the files concerned adult criminal justice and 1.5% juvenile justice. The FGR does not handle juvenile proceedings, so that category applies to state offices. Among state agencies, the State of Mexico accounted for 17.0% of files opened, Mexico City 10.2% and Guanajuato 7.8%. This distribution reflects each office’s reported file volume. It is not a population-adjusted crime rate or a ranking of prosecutor effectiveness, and the published totals do not establish why the number of openings changed.

The report separately counted decisions or conclusions recorded during the year in files at the initial-investigation stage. There were 1,904,464 such entries: 104,334 attributed to the FGR and 1,800,130 to state offices. State prosecutors also reported 225,936 decisions or conclusions in the complementary-investigation stage. These are not simply files opened and closed during 2025; decisions made during the year may relate to files opened in earlier years. INEGI also defines the reference unit differently across levels. For the FGR it uses a file based on the principal offense and principal responsible person; for state agencies, decisions can be counted by procedures associated with victims, accused people and offenses. One file can therefore generate more than one state-level decision. The totals should not be matched one-for-one against annual openings.

At the end of 2025, agencies reported 2,916,624 procedures still pending in investigation files, 10.4% more than a year earlier. The count included 2,889,673 adult-criminal-justice procedures and 26,951 juvenile-justice procedures. State agencies accounted for 2,884,601; the FGR reported 32,023. The federal count, however, covers pending procedures only at the initial-investigation stage because the FGR said it lacked information on its complementary-stage processes. The state figure includes both initial and complementary stages. Pending procedures can also come from files opened in earlier years, rather than only from the 2025 openings. These administrative records should not be equated with a count of unique legal cases or described as a directly comparable backlog without explaining the scope difference.

The FGR and state offices exercised a combined 81,209.1 million pesos in 2025 at current prices: 20,345.6 million for the FGR and 60,863.5 million for the states. At prices of the second half of July 2018, the real total was 57,930.3 million pesos, split between 14,513.5 million federal and 43,416.8 million state. The real total was 1.7% higher than in 2024; real FGR spending fell 1.1% and state spending rose 2.7%. Current-price and constant-price values use different price bases. INEGI replaced the report file on October 2 to remove incorrect statements on pages 10–12 saying Guanajuato’s prosecutor office had not supplied data on investigative police staff; the office had supplied the data, which were included in the results published on October 1. The correction changed those statements, not the national totals used here.
