Are there parts of the country that you feel has a good sense of community for young families that’s not based on religion?

Where I live in the US it feels very isolated. Although I live in a suburb, I don’t really know my neighbors or have a sense of community. I just traveled out of the country recently and everyone was so kind and you can feel that sense of community, especially with a having a young child. Adults were helping me with my toddler, even play with him. Are there parts of the country that are like that but aren’t solely based off of religion?
