According to this article, the Amish population in the United States has increased rather dramatically to about 300,000. I find this number surprising because it means that roughly one in a thousand people in the United States is of the Amish faith.
There is or was a community of Amish people living somewhere between Scottsburg and Salem, Indiana. I was born in Salem. When I lived in Scottsburg back in the 1980s, I saw some of them in a buggy while driving to Salem, even though I didn't take that trip very often. I would on rare occasion see a few of them in Scottsburg, and I met and talked with an Amish young man in the mid-1980s. My impression of him was not very favorable. He seemed to me to be remarkably ignorant, but I assume that his faith does not encourage knowledge beyond what he needs for life in his community. Because of this, I feel like his faith is repressive, although he no doubt chooses that lifestyle.
