Neither column is better. A state with more organizations per resident has more registered nonprofits per head, which may reflect population size, the presence of a large city, or how many small organizations bothered to register — the data cannot separate those.
What makes these two hard to compare
- The state is an organization’s address of record. A national charity headquartered in one state operates in all of them, and its revenue is counted where its mail goes.
- Revenue totals sum filings from different years, because organizations report on their own fiscal years. A state total is not a figure for any one year.
- 2024 Census resident population is the denominator for the per-resident rows. It counts people who live there, not people the organizations serve.
- Churches need not apply for recognition, so states differ partly in how many churches chose to apply.
