Warren County Jail’s population is estimated to increase to 430 inmates in 13 years if the current rate of incarceration remains unchanged and continues to rise.It was also noted about one-third of the county’s current jail inmates stay one day or less, while over 70 percent are in jail less than two weeks.Those figures were presented Tuesday to members of the county Jail Oversight Committee, who met for an information only session with County Technical Assistance Service jail management consultant Jim Hart, who is assessing the jail before possible expansion. Of the 430 inmates projected in 13 years, 94 will be female and 336 will be male. The numbers were generated using several factors, including the current population in Warren County and the average daily jail population to calculate the possible increase.
