Strong Towns BloNo will host a film screening this week about how the decline in social capital is eroding American communities.

The 2023 documentary Join or Die is based on Harvard University professor Robert Putnam’s landmark research connecting distrust and civil unrest with plummeting enrollment in clubs and other civic organizations—captured in his best-selling book Bowling Alone, published in 2000 as a follow-up to an essay first written in 1995.
