There was a decrease in San Antonio's index crime rate between 2010 and 2020, from 7268.8 to 5037.3 or a reduction of 31%. Property crime—tracked as burglary, larceny theft, and vehicle theft—accounts for a majority of crime in San Antonio over the last decade, and this showed a decline.
There was an increase in homicides, robberies, and aggravated assaults, while property crime continued to decline. In preliminary data from 2021, this upward trend in violent crimes seems to continue with a 33% increase in robbery and 25% increase in rape in the same time period between 2020 and 2021.
Between 2010 and 2020, SAPD provided the data for crime as defined by Uniform Crime Reporting (UCR), which included: criminal homicide, forcible/legacy rape, robbery, aggravated assault, burglary, larceny, motor vehicle theft, and arson.
In 2021, the San Antonio Police Department, based on federal and state mandates, began a transition from UCR to the new National Incident-Based Reporting System (NIBRS). SAPD officially began submitting monthly NIBRS data to the Texas Department of Public Safety, beginning in January 2021. These metrics were later provided to the Federal Bureau of Investigation (FBI).
Under NIBRS, the list of index crimes expanded and includes three categories: 1) Crimes Against Persons (e.g. assault, homicide, human trafficking, kidnapping/abduction, and sex offenses), 2) Crimes Against Property (e.g. arson, destruction/damage/vandalism, larceny/theft offenses, motor vehicle theft, robbery), and 3) Crimes Against Society (e.g. animal cruelty, gambling offenses, weapon law violations).
Additionally, reporting rules under the NIBRS system are different than UCR rules, which prevents historical comparisons. Baseline data and 2030 goals will be calculated when SAPD finalizes their transition to the new system.
