A Perfect Union: Most Americans Want More Diversity, Not Less

Survey finds majority of White Christians favor a more multicultural America, challenging fears about ‘Great Replacement’ anxieties

COPENHAGEN — A new study offers a surprising counterpoint to widespread assumptions about American attitudes toward diversity. Rather than fearing demographic change, many Americans appear to favor a more diverse future, and that includes groups often portrayed as most resistant to such change.

The research, published in the journal Ethos, surveyed nearly 1,000 Americans and found that two-thirds of respondents indicated a preference for a more ethnically and racially diverse United States than what currently exists. Notably, this included many White Christians, the demographic often cited in discussions around “Great Replacement” fears.

Only 1.1% of respondents expressed a preference for an ethnically uniform America, while just 3.2% wanted a religiously homogeneous population. These findings challenge the narrative that demographic change is fueling widespread backlash among White Americans.

The Great Replacement theory, which claims White Christians are being systematically replaced by non-White immigrants, has been cited in several high-profile attacks, from Pittsburgh to Christchurch. Yet when researchers asked Americans to envision the ideal demographic makeup of their country, the results told a more complex story.

Americans Want More Diversity Than They Think Exists

The study, led by led by Séamus Power from the University of Copenhagen, used a novel approach that revealed key blind spots in how Americans perceive their country’s demographics. Before asking about preferences, researchers had participants estimate current racial and religious makeup. The results were quite remarkable.

Respondents believed White Americans made up just 37.7% of the population when the actual figure is about 61%. They overestimated nearly every minority group’s share. Black Americans were estimated at 19.1% of the population (actual: 13%), while East Asians were pegged at 7.9% (actual: 4%).

Despite believing the country was already highly diverse, participants still allocated even greater diversity in their “ideal” version of America. When asked to design their preferred demographic balance, they allocated 39.5% to White Americans, which is more than they believed currently existed, but still representing a more multicultural country than today.

The research team surveyed 986 Americans in August 2021. The sample closely matched national demographics, with 71.4% White respondents, 10.8% Black, 5.3% Hispanic, and representation across the political spectrum.

Rather than asking vague questions about diversity, the survey required concrete decisions. Participants allocated specific percentages across seven ethnic groups and eight religious categories to design their ideal national makeup.

White Christians Also Show Preferences for Diversity

One of the study’s more striking data points concerns White Christians, the group most often linked to demographic anxiety in political discourse. Among this group, 66.3% had ideal demographic responses indicating a preference for greater ethnic and racial diversity than the 2020 baseline, based on a calculated diversity index. That proportion was lower than the 82.2% found among non–White Christian respondents, but still represents a majority.

When it came to religious composition, half of White Christian respondents had a diversity index above the 2020 religious baseline. While this does not directly indicate a desire for more diversity, it suggests a substantial portion envisioned a more religiously varied nation.

Participants generally showed modest preferences for their own group. White respondents allocated about 10 percentage points more representation to Whites than other groups did. Black participants gave their own group 4 to 6 points more representation than others assigned to them. Hispanic respondents did the same by 3 to 4.5 percentage points.

Still, no group favored total demographic dominance. The study found that across racial and religious categories, the average “ideal” reflected inclusion of multiple groups. The authors note that the overall trends in ideal group sizes were “more similar than different.”

When it came to religion, nearly 60% of respondents had ideal responses that indicated a preference for greater religious diversity than the status quo in 2020. Among the minority who preferred a mono-religious population, atheists made up the largest share; 15 out of 31 respondents envisioned an all-atheist country. The remaining included nine who preferred an all-Protestant America and others who chose Catholic, Muslim, or Mormon homogeneity.

Extremist Views Remain on the Margins

While most Americans did not favor exclusionary visions of the country, a small subset of respondents reported extreme preferences. Of the 1.1% who wanted a mono-racial nation, nine envisioned an all-White country, while one each preferred all-Black or all-Native American populations.

Though these numbers represent a small minority, when extrapolated to the national population, they could translate to hundreds of thousands of people. The researchers caution that such groups, while small, can have disproportionate influence, especially if they act violently.

Still, the overall results tilt toward inclusive ideals. Even accounting for social desirability bias (the possibility that people gave socially acceptable answers) the margins were too large to attribute entirely to posturing.

Political orientation influenced demographic accuracy in nuanced ways. For instance, people identifying as neither left nor right were more likely to underestimate the size of the White population, while those on the political extremes, both left and right, ended to be more accurate in estimating demographic proportions. These differences were specific to certain groups, not generalizable across all demographic categories.

What This Means for America’s Future

The study’s findings raise important questions about how media coverage shapes perceptions of public opinion. Events like the Charlottesville rally or January 6th Capitol riot attract intense attention, potentially amplifying the perceived prevalence of extremist ideologies.

The research also suggests a gap between political messaging and public sentiment. Politicians who invoke replacement fears may be appealing to a narrower base than commonly assumed. While these appeals can still mobilize dedicated supporters, they don’t appear to reflect majority attitudes.

Immigration patterns have changed substantially over the decades: 84% of immigrants in 1960 came from Western countries, compared to just 13% in 2018. Despite these shifts, many Americans still favor a diverse future, at least on the national level.

The study focused on ideals for the U.S. as a whole, not for individuals’ local communities or personal networks. As the authors note, Americans may simultaneously support diversity on a broad level while preferring more homogeneous environments in daily life. The survey’s timing, conducted in 2021 amid intense political polarization, also leaves open the question of whether these views are stable.

Even so, the results suggest that multiculturalism is not inherently controversial. Many Americans across racial, religious, and political lines envision a future that includes more diversity, not less. As the researchers cautiously conclude, the idea of a multicultural America “may be as American as apple pie.”
