Our report gives cities and counties a long-needed tool for fighting mass incarceration: a guide to preventing needless jail expansion. With jail populations having tripled in the last three decades, overcrowding in local jails is common — but there are simpler, cheaper, and more just solutions to jail crowding than building a new or bigger jail. We lay out 33 questions, and a list of best practices, to help local decision-makers understand the true costs of — and alternatives to — jail expansion.
