Police Numbers in the US

According to a 2018 report by the Bureau of Justice Statistics, local police departments in the US employed 601,011 full-time employees, 77.5% of whom were sworn personnel, whereas the rest were civilian employees. Together, these half a million individuals worked for 11,824 local police agencies nationwide. The highest number of police personnel were employed by the state of New York (79,689), followed by California (54,295) and Texas (49,961). On the other hand, Vermont had the least number of employees in local police departments, only 833. As for the number of local police departments, Pennsylvania had the highest, 896. The state of Hawaii was the least prolific, with only four local police departments in the entire state. There were a total of 18 police departments that served populations of one million or higher, and collectively, they employed 21% or one-fifth of the full-time sworn officers in local police departments. 

The Shortage Crisis

According to the BJS, in 2018, the US had 241 full-time sworn officers per 100,000 residents, a number which was 251 in 2008. In 2018, the Washington Post reported a decline in applications for police jobs. In the state of Seattle alone, job applications had declined by 50%. A 2023 PERF survey report stated that while police departments were hiring more police officers than in previous years, they were losing employees faster than new ones could be recruited. In 2022, police agencies received almost 50% more resignations than they did in 2019, whereas retirement numbers were 20% higher than they were in 2019. Thus, overall, sworn staffing dropped by 5% in the past three years. You can take a look at the 20 Safest Places To Retire in the US for some post-retirement insights. 

As a result of the decreased numbers, police departments are facing what the Justice Department has referred to as a ‘historic’ staffing crisis, as reported by USA Today, back in October 2023. As a result, 30 law enforcement and community leaders drew up a report on recommendations to improve hiring numbers. One of the recommendations included modernizing eligibility requirements; for example, stringent checking on the physical standards required of an officer could be postponed till completion of training at the police academy. Recommendations were also given regarding introducing new incentives such as retention bonuses, tuition reimbursement, and elimination of caps on pension and overtime pay. According to USA Today, police protests during the Coronavirus pandemic were one of the biggest reasons why numbers in the police force were dwindling. 

The Savior – Technological Advancements 

As police numbers continue to drop, advanced technological tools can bring increased efficiency to police workflows. According to a report by Thomson Reuters, technology can be one of the ways in which the police can cope with its worsening shortage crisis. Out of all the respondents that the report surveyed, one-third said that keeping up to date with technology was one of the top three concerns within their department. The report also mentioned that departments that struggled with increased crime rates made it a higher priority to invest in law enforcement technologies.
