Monroe County’s jail population stood at 205 on Saturday (Oct. 31), which is up 1 from a week ago. But it still marks the 25th day in a row when the count of prisoners has been below the ACLU’s version of the jail’s functional capacity, which is 229.

In the last week, the population twice dipped under 200.

The highest number in the last week was 212, on Tuesday, which was still 17 under the ACLU’s functional cap.

Chart by The B Square with data from the Monroe County jail.

Monroe County’s jail data dashboard includes snapshots of basic counts, demographic profiles, and the types of crimes prisoners are charged with. The dashboard is updated routinely, which means Monroe County residents don’t need to wait for weekly updates from a news outlet.

The B Square has tracked the numbers starting on July 21, when the jail held 247 people. Ten days into that span, the 10-day rolling average was about 254. The most recent rolling 10-day average, on Saturday (Oct. 31) was about 204.

That’s 25 under the number that the ACLU gives as the jail’s functional capacity in its federal lawsuit, which it filed in July on behalf of jail inmates. Monroe County sheriff Ruben Marté has given a lower figure for functional capacity. His July overcrowding report started with 294 reported beds, subtracted housing that he said cannot be treated as general-population space, leaving 233 available general-housing beds. Applying the same 80% principle yields a functional capacity of 186.

The difference between the two jail population snapshots at the start and the end of the period The B Square has tracked does not capture the turnover in the jail during that period. Of the 247 people who were there on July 21, 78 of them were still there on Oct. 31. That means 169, or about 68% of the people who were in jail at the start of the period, had left by the end.

At the same time, 127 people who arrived after July 21 were still incarcerated on Oct 31. The 78 people who were present at both endpoints, together with those 127 later arrivals, account for the current population of 205.

That comparison still does not capture people who arrived after July 21 and then left before Oct. 31. There were at least 856 departures from the jail during that span. Some of those departures could have been by the same person.

Among those who departed during the time The B Square has tracked the numbers, the median length of stay was 2 days.

Over that same period, the average daily population was about 231. The highest count was 264 on July 31. The lowest was 196 on Oct. 23.
