Not beautiful but very interesting. Not shocked that christianity would grow or islam decrease a bit in favor of secularism, but very shocked in any growth in Zoroastrianism. I suppose there could be some noise in the data
Wonder how much is people actually changing their opinion vs being able up answer more honestly with the cracks showing
hmm, I wonder of there could be any other reason people the U.S. (many of whom are immigrants) wouldn’t reply that they are Muslim on a survery.
The significant drop in Bahai is interesting. Anyone better informed with a theory?
Your linked source contains only the data for 2025.
why clump none with other?
“the median credibility interval across the survey being ± 5.2 percentage points”
This is interesting data, but the bar chart format isn’t very elegant and obscures the information people are most interested on: change from time A to time B.
Have you tried plotting this data as a slope graph? It’s similar to a line graph.
These are fundamentally not comparable. The [2009 survey](https://paaia.org/wp-content/uploads/2018/08/2009-SURVEY-of-Iranian-Americans.pdf) used a single “other” category while the 2025 survey also used Agnostic and Atheist. The 2009 survey pollster used a different pollster that conducted a phone survey using a list of Iranian surnames. The 2025 survey used a much more complicated sampling procedure that went by Iranian ancestry, something which would obviously be more representative of people with partial Iranian ancestry than surnames.
