It's a town that only hits the news every few years, usually due to a corruption scandal or a bit of violence in their public schools, but take a look at the village of Kiryas Joel, just upstate from New York City.
The local religious police (not a legal police force, but still thugs with sticks) wander around enforcing a long list of religious rules lifted straight from the darker corners of the Talmud. Think of it as a Jewish form of Saudi Arabia, or an American Taliban.
Genders are strictly separated in public - separate entrances and even separate buildings, and no line of sight between men and women. Even families are separated.
Children largely attend unlicensed religious schools. The boys do, anyway. And there are a shitload of kids in this village. They typically top the list of the highest birth rate in a single community in the United States, due largely to their religious opposition to birth control or family planning.
Those few KJ kids in area public schools bring with them an army of sue-happy parents and angry rabbis, who take over school board meetings with raucous protests against secular education. The state of New York has struggled to find funding and teaching resources for public schools in this area, and non-Hasidic families in the county report regular harassment and intimidation during elections for school board leaders. The school district has constant battles over dress codes, library books, and the role of female teachers around male students.
KJ also typically has the lowest per-capita income in the country, at around $4,500 annually according to this article. This is due to the massive number of children in the village, but also the fact that most working-age women are forbidden to work and most working-age males are pushed into religious studies rather than paying jobs.
It's long been the state's biggest magnet for food stamps, direct cash payments, WIC vouchers, housing vouchers, and other forms of low-income assistance. This place takes in more welfare than the poorest parts of the Bronx.
The village is legally incorporated under New York law, with voters, a tax structure, and an elected government. But as the town is virtually 100% a single religious sect, the local rabbi(s) control all political matters. There have been disputes in the past where feuding rabbis split the town's voters on a mild issue, and they treat it like a neighborly holy war.
It's utterly bizarre, and claims of child abuse and fraud run rampant, but the state hasn't yet stepped in to disincorporate the village.
