The next presidential contest for Republicans and Democrats will take place in Michigan on February 27; however, unlike in other states, Michigan will hold a primary and a caucus. Although both parties will hold primaries on February 27, Republicans will also hold a caucus on March 2 which will award the majority of the party’s delegates. Republican Presidential frontrunner Donald Trump will be on both ballots as well as several other Republican nominees who have officially dropped from the race. The following are some key facts about Michiganders based on data collected by PRRI in 2022:

• The median age of adults in Michigan is 46, lower than the median age for all Americans (48).
• Four in ten Michiganders (39%) have a high school diploma or less education and three in ten have completed some college (30%). In comparison, only 17% of Michiganders have a college degree and 13% have a post-graduate degree.

Michigan’s Religious Diversity and Religious Affiliation at the County-Level

Religious Diversity in Michigan

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 Michigan is 0.722.
