In the United States, the average age of homicide victims in 2025 is the highest recorded since at least before 1976. That is what the FBI data seems to indicate, according to criminal analyst Jeff Asher.

The best source of data on homicide victims in the U.S. is the FBI’s Supplementary Homicide Report (SHR). The SHR is a collection of data from the FBI on all homicide victims in a given year. Agencies report details about the month, the age of the victim and the offender, race and sex, the circumstances behind the homicide, and what type of weapon was used.
The SHR is somewhat difficult to address. Not all states participate (for example, the state of Florida does not report) and not all agencies report every year. Many computers can today manage a spreadsheet of 20,000 rows and 100 bytes, but the SHR is produced in ASCII format, which is incredibly difficult to use.
Fortunately (and this is an understatement), Jacob Kaplan has studied all the old SHR data dating from 1976 to 2024 and has made it reasonably easy for everyone to access. Typically, between 80% and 90% of the estimated number of homicides each year appear in the SHR, although this figure has been increasing in recent years thanks to Florida starting to report again. The increase in 2024 likely reflects that the estimate for that year needed to be revised upward by several hundred, but more than 90% of last year’s homicides appeared in the SHR.
The analysis of the data for 2025 should be taken with caution because the data are not definitive. Obviously, the year is not over, but even the agencies that have reported have not done so completely. However, it is a major victory that the FBI’s monthly reports include the SHR.
If we go back to the SHR until 1976, we see the trend that the average homicide victim is ageing.
The average homicide victim so far, during this current year, is nearly 36 years old, older than any of the last 50 years of SHR collection. Last year, the average homicide victim was slightly younger, although it is possible that this year’s average age will decrease when the data is fully analysed. Be that as it may, the age of homicide victims in 2024 and 2025 was the highest in more than half a century of data collection.
It is not just a case of the peculiarity of the FBI data. CDC homicide data shows a similar increase in the average age of the homicide victim, which matches almost exactly the FBI’s average age virtually every year since 2001 (higher due to the inclusion of 9/11 in the CDC data).
If we break down the annual homicide victim proportion by age ranges, it shows that just over 60% of homicide victims in the last two years were between 18 and 44 years old, a considerably lower amount than just five years ago.
