UPDATE: Sheriff Ken Furlong on Wednesday said the reason the data is showing the large difference in numbers is because the data only began to be collected in December 2024, and does not reflect full data for that full entire year.
He said he does not know if the data on the chart for 2024 accurately reflects December arrests either due to the fact that the sheriffs office only began officially tracking in 2025.
We are leaving the original story below with the data in the chart as that is what is publicly available for the board of supervisors meeting taking place tomorrow, but felt it imperative to include Sheriff Furlong’s clarification for accuracy.
Original story:
On Thursday, the Carson City Sheriff’s Office will present their biannual “State of the Jail” report to the Board of Supervisors, which includes statistics covering everything from inmate demographics, which agencies are making arrests, the deaths of prisoners and more.
While fluctuation changes across categories are always present in reports (there was a 3% increase in bookings between November and December, but a 2% decrease between 2024 and 2025 for example), one category showed a significant change of rate: immigration.
According to the detention division statistics, in 2023, it appears immigration status was not a category tracked by the Sheriff’s Office.
However, in 2024, those numbers are included in the report, showing that seven non-US citizens were arrested and of those, ICE was notified of four and all four were placed on holds for the federal agency.
By 2025, those numbers exploded.
By the end of December 2025, 137 non-US citizen intakes were recorded, a massive 1,857% increase from the prior year.
Of those, ICE was notified of 78 (a 1,850% increase), and 34 were placed on a hold for the federal agency (750%).
By the given numbers, in 2024, non-US citizen intakes made up 0.25% of 2,763 intakes. In comparison, in 2025, they made up 5.06% of the 2,708 people booked into the jail.
That’s about a a 1,897% increase (roughly a 20× jump) in just one year.
The Board will hear a full presentation going over the numbers, and why they increased so significantly, during this Thursday’s Board of Supervisors meeting.
Additional State of the Jail matters:
There have been no inmate deaths to report in the preceding six months at the Carson City Jail.
Between July and December 2025, the monthly population at the jail was around 167 inmates, with the average stay at around 100 days. Men made up 78% of the total population, with women at 22%.
At present, new “inmate communication services” are being installed within housing units, which will allow for tablet visitation and educational inmates to be accessible to all inmates by the end of this month.
