Religious Diversity in New Hampshire

In addition to 2022 statewide data, the 2020 PRRI Census of American Religion provides reliable county-level religious affiliation data, including our Index of Religious Diversity, which measures variations in the concentration of global religious populations. The index is calculated so that a score of 1 signifies complete diversity — every religious group is of equal size — and a score of 0 indicates a complete lack of diversity and one religious group comprises the entire population of a given county.

Nationally, the average religious diversity score by county is 0.625. The average religious diversity index score for the state of New Hampshire is 0.785.

New Hampshire’s ten counties are listed from highest to lowest Index of Religious Diversity score:
