Here we provide updates to the 2016 CNN article "Pop. 17,049: Welcome to America's largest jail" by Breeanna Hare and Lisa Rose.
There are 3,096 county jail jurisdictions in the United States and the Los Angeles County jail system is the largest. Because Los Angeles County’s population is larger than that of most U.S. states, its jail system held more inmates than all jails in any one of 37 U.S. states, according to 2019 Bureau of Justice Statistics Census of Jails statistics. That same agency reported that, in 2021, a little more than 2% of all U.S. county jail inmates were in the custody of Los Angeles County jails.
In the 2023-2024 County of Los Angeles budget, the Sheriff’s Department, which operates county jails, had a total budget of $3.78 billion, with $966.8 million of that (or 26%) for its jail system. The portion budgeted for the jails include $907.5 million for payroll and benefits; $52.3 million for services and supplies; and $7.3 million for equipment. Source: CEO of Los Angeles County.
If you are arrested in Los Angeles County, there is a 32% chance that you will end up in the county jail system. In the first six months of 2023, there were 97,021 arrests in Los Angeles County and 30,609 of these were booked into county jail. This was a much lower arrest and jail incarceration rate than in pre-pandemic 2019, when, of 303,363 arrests during all of that year, 110,941 (37%) ended up booked into jail.

In the first half of 2023 (through June), Los Angeles County had an average daily inmate population of 13,871 within its jail system (down from 17,070 for all of 2019, due to reducing the incarcerated population during the early part of the COVID-19 pandemic in 2020). Of the 2023 average daily inmate population, 1,470 were female.

By December 2020, there were 2,447 more inmates in custody than Los Angeles County’s jails were rated to hold. Earlier in 2020, from May through July, the county's jail population fell below its rated capacity of 12,406. This occurred because the county responded to skyrocketing COVID-19 infection rates in its overcrowded jail facilities by releasing less-serious offenders. The only other time in recent memory in which Los Angeles County's jail population actually dropped below its rated capacity was from March through July of 2011.

The racial demographic for Los Angeles County’s jail population in the second quarter of 2023 was 55% Hispanic, 29% African American, and 13% White. Asians made up less than 1% and American Indians even less. African Americans made up an overly disproportionate share of the jail population as compared to their proportion of the overall county population (about 8 percent). To be clear, this disproportionate representation is not unique to Los Angeles County and is seen in jail populations across the nation.
In the past, the majority of Los Angeles County’s jail population was composed of nonviolent offenders. In pre-pandemic 2019, those charged with assaultive/violent offenses (crimes committed physically against persons, weapons charges, and sex crimes) were 45% of the inmate population. In 2020, however, because of efforts then to reduce the jail population due to the COVID-19 pandemic, that percentage grew to a majority of inmates at 54%. In the second quarter of 2023, that percentage stands at 65% of the jail population.
In the second quarter of 2023, 50% of inmates awaited trial or sentencing in Los Angeles County’s jail system. About 7% were sentenced specifically to time in county jail, 8% were sentenced to jail under AB109, and 22% were partially sentenced. About 6% awaited transfer to a California state prison. About 4% were held for parole violations. About 3% awaited transfer to mental health hospitals.
Besides Los Angeles County’s jail system being the largest in the nation, it is also one of the largest mental health institutions in the nation. The number of inmates in the Los Angeles County jail system with mental health problems increased 123% from 2010 through 2023 (4). With few other options in the criminal justice system, a growing number of mentally ill persons in Los Angeles County end up incarcerated in jail. In the second quarter of 2023, the average number of inmates with mental health problems accounted for 41% of Los Angeles County's jail inmate population (up from 35% in pre-pandemic 2019). The challenge of properly handling this growing number of inmates with mental health issues only further strains an already crowded jail system.

Unlike many jail facilities in the United States, the Los Angeles County jail system offers rehabilitation, educational, and vocational programs. In the second quarter of 2023, and average of 36 inmates (including one woman), after extensive training, were assigned to fire-fighting duties at California Department of Corrections and Rehabilitation camps, including those operating in Los Angeles County. Other in-custody programs in which inmates participated were the Conservation Work Program, involving an average of 1,227 inmates in the second quarter of 2023, the Education-Based Incarceration Program (EBI) (traditional and nontraditional education for inmates), the Fire Camp Training Program (training fire fighters for state fire camps), the Back on Track Program (helping inmates with post-incarceration) and the Substance Treatment and Reentry Transition program (START) (treatment for inmates with substance abuse issues and help with transition into post-incarceration).

To oversee and care for its huge inmate population, the Los Angeles County Sheriff’s Department currently assigns about 27% of its total staffing (4,712 employees) to its Custody Division. About half of these are deputies. The rest are civilian staff such as custody assistants, medical personnel, administrative, kitchen and other support staff.
