Diversity | Ethnicity

This one could well be described as lack of diversity…..White/ Caucasian 84%, Hispanic 12%, African American 1%, Native American 1%, Asian 2.5%, Pacific Islands .25%. I rounded up down a little so the math is “fuzzy”. But the bottom line is that the Boise Metro area is predominately Caucasian.


A little less than half of the state of Idaho according to statistics is religious. The leading religion in Idaho is LDS, but only 16% of the total 26% in Idaho resides in Boise. Following behind LDS we have Catholic at 7%, Baptist 3%, and Methodist 3%. There are a few catholic schools in Boise. St. Marks Elementary school, St. Mary’s, Sacred Heart, St Joseph’s, and Bishop Kelly High School. With Idaho being 2nd behind Utah in LDS population we have a Boise temple and recently, a new temple was built in Meridian. Scattered through out the Treasure Valley are many Christian and Catholic churches and LDS churches you will find primarily in the Meridian area. There are a handful of Buddhist temples in the area, a Hindu Temple, and a Boise Synagogue.
