How to Look Up Madison County Jail Population Data
There are four practical places to look. The Sheriff's office publishes operational rules and links on its Jail Division page. The Illinois Department of Corrections publishes annual county jail inspection reports. The Bureau of Justice Statistics releases an Annual Survey of Jails and a Census of Jails covering Illinois facilities. The Vera Institute's Incarceration Trends tool produces a county-level profile based on those sources.
For real-time daily population, the most direct check is a phone call to the Sheriff's Office at (618) 692-6087. The inmate information line at 618-692-1064 covers individual detainee charge and bond information rather than aggregate counts. Individual-inmate name lookups belong on the inmate records page; this page focuses on the bigger picture.
Madison County Jail Capacity Overview
The Madison County Jail at 405 Randle Street is the county's only jail facility. The exact rated capacity is not published in the inspected Sheriff or jail pages. State jail standards inspection reports and the county budget are the better sources for that number. Anyone needing the current rated capacity should check the most recent IDOC County Jail Standards inspection or the most recent county annual budget.
| Facility | Address | Source for Current Capacity |
|---|---|---|
| Madison County Jail | 405 Randle Street, Edwardsville, IL 62025 | IDOC county jail inspection or current Madison County budget |
| Sheriff Administration | Same site | Sheriff administrative office, (618) 692-6087 |
Capacity is one number. Daily population can run above or below capacity depending on bookings, releases, transfers, and any state or federal holds. National-level context from BJS Annual Survey of Jails is useful when comparing year-over-year change.
County Jail vs IDOC Prison vs Federal BOP
The Madison County Jail is a county jail, not a state prison. It mainly holds pretrial detainees and people serving short sentences. The Illinois Department of Corrections runs state prisons. The Federal Bureau of Prisons runs federal prisons. Each system reports population differently.
- Madison County Jail – pretrial holds, short county sentences, parole violators awaiting return, and some IDOC writs.
- Illinois DOC – people sentenced to state prison; population data published by IDOC.
- Federal BOP – people sentenced to federal prison; population data published by BOP.
- U.S. Marshals – federal pretrial detainees sometimes housed in county jails under contract.
Daily Population Metrics to Look For
A complete jail population picture covers more than one number. Useful daily metrics include the average daily population, the pretrial share, the sentenced share, the misdemeanor and felony split, the federal hold count, and the average length of stay. Madison County does not publish a live dashboard with these numbers on the inspected pages, so users may need to combine the IDOC inspection report and the BJS Annual Survey of Jails to build a recent estimate.
| Metric | What It Measures | Best Source |
|---|---|---|
| Average daily population | The mean number of people held each day in a year | BJS Annual Survey of Jails; county budget |
| Pretrial vs sentenced | Share held before trial versus those serving sentences | BJS Annual Survey; Vera county profile |
| Misdemeanor vs felony | Severity of charges | Court records aggregated; Vera |
| Federal holds | U.S. Marshals or ICE detainees | Sheriff's intergovernmental contracts |
| Average length of stay | Time between booking and release | BJS Annual Survey |
Programs Inside the Madison County Jail
Programming can influence both behavior inside the facility and outcomes after release. The jail FAQ notes GED programming through Lewis and Clark Community College, free Khan Academy on jail-issued tablets, and non-denominational church services on Saturday and Sunday. Detainees can also use video kiosks for tablet messaging and video visits.
The Madison County Mental Health Court and the Madison County Assessment and Treatment Alternative Court divert qualifying defendants out of jail and into supervised treatment. Those diversions affect the jail's daily count because they move people from custody into community supervision. Veterans diverted into the Veterans' Treatment Court follow a similar path.
Commissary, Phone, and Mail Systems as Operational Signals
The Madison County Jail's vendor list signals how the facility is run day to day. Keefe is the commissary provider, IC Solutions runs phone and video visits, Access Corrections handles money deposits, and Hamilton Books is the required book source. Personal mail is digitally processed at a contractor in Phoenix, Maryland. Tablets carry Khan Academy, messaging, and the detainee handbook.
These operational decisions track Illinois jail standards. The county's January 1, 2022 rule limiting white undergarments to the commissary, and the December 27, 2021 transition to digital personal mail, are visible operational changes that affect daily life inside the facility.
BJS and Vera National Context
The Bureau of Justice Statistics publishes an Annual Survey of Jails and a Census of Jails covering local facilities. National jail population, pretrial share, length of stay, and demographic breakdowns appear in those reports. The Vera Institute's Incarceration Trends tool builds a county profile from BJS and other public data sources.
| Comparison | Rate per 100,000 Residents | Source |
|---|---|---|
| National jail rate | Refer to most recent BJS Annual Survey | BJS |
| Illinois jail rate | Refer to most recent BJS state rollup | BJS |
| Madison County rate | Refer to most recent Vera county profile | Vera Institute |
Comparing county, state, and national rates per 100,000 residents helps put any single number in context. A year-over-year change in Madison County matters more if it diverges from the state and national trend than if it tracks them.
Population Trends Over Time
Jail population trends shift with charging policy, bond reform, court backlogs, and pretrial services. Illinois passed the Pretrial Fairness Act, which changed how cash bail is set across the state. That kind of statewide policy shift moves the pretrial share of jail population in counties like Madison.
Bond reform, e-filing, specialty courts, and remote proceedings all shape the daily count in different ways. Court backlogs cleared since the pandemic-era closures also influence the pace of dispositions and release.
Searching for Madison County Inmate Records by Name
This page covers aggregate population data. People looking for a single detainee's charge, bond, or current custody status should use the jail inmate information line at 618-692-1064 or visit the Madison County inmate records page for the full walkthrough.
Where the Data Comes From
The most authoritative sources for Madison County jail population data are official ones. The IDOC county jail inspection report covers state-mandated standards and any deficiencies. The BJS Annual Survey of Jails gives the national context. The Vera Institute's Incarceration Trends profile builds a county-level summary. The Madison County budget covers staffing, facility cost, and operating funding for the jail. Reporters, researchers, and the public can pull on those sources to build a complete picture.
Note: Numbers in published reports lag real-time bookings by months or even a year, so use them for trend context rather than as a live count of who is in custody today.
Sheriff Staffing and Jail Command
The Madison County Jail is staffed by sworn corrections deputies and civilian support personnel under the Sheriff's command. The Sheriff's administration page lists Captain Jerry Endicott as Jail Administrator at (618) 296-4832 and Captain Blake C. Sellers as Jail Superintendent at (618) 296-4847. Sheriff Jeff C. Connor oversees both jail and patrol operations.
Population data on its own does not tell the staffing story. Jail standards inspections look at the staff-to-detainee ratio, the medical staffing, and the physical plant separately from the daily count. The Madison County budget breaks staffing out by sworn position, civilian support, and contracted services.
Operational vendor contracts also affect daily life inside. Keefe handles commissary, IC Solutions runs phone and video visits, Access Corrections handles money deposits, Hamilton Books is the required book source, and the digital personal mail vendor in Phoenix, Maryland scans incoming mail before tablet delivery. Each contract is a budget item the Sheriff and county board manage.
Pretrial Fairness and Bond in Illinois
Illinois implemented the Pretrial Fairness Act, which removed cash bail as the default in many criminal cases. The change moved decisions about release to a structured risk-based hearing rather than a money-based release. That shift directly affects the pretrial share of jail population in counties like Madison.
The Pretrial Fairness Act also added time limits to release hearings and detention orders. The Circuit Court holds the hearings, the State's Attorney files detention petitions when sought, and the Public Defender represents indigent defendants. Defense counsel can challenge the State's basis for detention, and the judge sets conditions if release is ordered.
Open Data and Public Reporting
Madison County publishes a range of open data through its main county portal, including the annual budget, audit reports, and elected officials directories. Jail population is not part of a live dashboard on the inspected pages, but the budget and audit material covers the cost side of running the jail, the staffing, and the contracted services.
For deeper statistical context, the Bureau of Justice Statistics publishes the Census of Jails on a multi-year cadence and the Annual Survey of Jails between censuses. Both reports cover Illinois facilities. The Vera Institute pulls those numbers into county profiles, and Illinois Department of Corrections inspection reports cover compliance with state county jail standards.
Researchers building a Madison County jail population picture should treat any one source as a snapshot rather than a complete story. Combining the state jail inspection record, the BJS national jail counts, the Vera Institute county profile, and the Madison County annual budget gives the most balanced picture of how the Madison County Jail population sits relative to capacity, staffing levels, and statewide pretrial and sentenced trends.
