The line chart shown below shows the number of arrests on a monthly basis in San Jose in 2025. The data displayed in this chart was gathered from the FBI’s Arrest Data API for the San Jose Police Department. Number of arrests seems to vary considerably by month, with the numbers being relatively lower in the early months of 2025, then rising slightly from the spring into early summer and gradually tapering down over the remainder of the year. It is impossible to determine the causes for these monthly differences from this graph alone, however, I speculate that they may relate to weather patterns and seasonal economic trends.
The animated bar chart labeled “Arrests by Crime Category 2025 - Animated” shows the changes in top category of arrest reason on a monthly basis in San Jose in 2025. This chart is based on San Jose City’s dataset on police calls, which breaks out whether an incident included an arrest and the dispatch’s original reason. Top categories vary by month, but the top several remain fairly consistent between Misdemeanor DUI and Narcotics Want. Certain categories, such as Felony or Misdemeanor Want (referring to an incident involving a wanted person) and Pedestrian/Vehicle Stops were excluded from the graph due to lack of clarity as to the original crime the individuals were wanted or stopped for. A large number of arrests corresponded to these excluded categories, explaining the seemingly much smaller monthly numbers compared to the linechart on page 1 based on the FBI’s data.
The table labeled “Top Crime Categories 2025” gives context to the animated bar chart with the yearly top categories for arrest reason. Much like the animated bar chart, this table is based on San Jose City’s police calls dataset. The top two categories for 2025 seem to be “Misdemeanor DUI” and “Narcotics”. Other categories of high frequency for arrest reason include Disturbances (including family disturbances), Resisting Arrest, and several others. Disturbances may refer to criminal incidents of fights in public places, loud noises disturbing others, or using offensive words to try and incite a violent reaction (California Penal Code § 415 2025). The “Malicious mischief” category refers to such cases as property destruction or damage (including graffiti) (California Penal Code §§ 594–625c 2007).

This plot shows a heatmap of police calls involving Violent crimes in San Jose in 2026 (Year to Date). Which categories of crime are classified as “Violent” is defined in Appendix 1. The map shows a clear trend of violent crimes being more prevalent in San Jose’s North West, with the area surrounding San Jose International Airport and San Jose State University involving the highest number crime rates relative to population. Peripheral parts of San Jose appear to feature a much smaller number of violent crimes. As this plot is based on Year to Date data, it is possible these geographical trends may slightly change as the year progresses.
