“Growing up biracial in America means learning early that the world is uncomfortable with your complexity. Multitudes names the isolation that thirty-four million Multiracial Americans carry—often in silence—and refuses to let it stay invisible. Dr. Karabi Acharya weaves her personal story together with insights on the systems that shape, erase, and exclude Multiracial experiences. The isolation that Multiracial Americans carry is not just emotional. It is measurable. As a journalist, I know how rarely that story gets told with this kind of rigor and care. As someone who lives it, I know how much it matters. Read this book.”

—Soledad O’Brien, award-winning journalist, documentarian, and host of Matter of Fact with Soledad O’Brien

Multiracial people are the fastest-growing population in the United States, yet they remain almost invisible in our institutions, narratives, and data. Until recently, Americans were categorized as Black or White, sometimes Asian or Hispanic, without other options or the choice to identify as more than one. Even while long-overdue conversations about race have deepened, the thirty-four million Americans who identify as Multiracial have been left on the sidelines: unseen, underrepresented, and facing an epidemic of isolation as a result.

In Multitudes, Dr. Acharya—a Multiracial academic, public health leader, and lifelong activist for inclusion—blends groundbreaking research with personal stories, interviews, and vivid real-world examples to illuminate the Multiracial experience. The result is both mirror and manifesto: a stereotype-shattering, deeply human portrait of identity, resilience, and connection that argues that embracing our complexity—our multitudes—is not a barrier to wholeness but the path to it.

Urgent, inspiring, and essential, Multitudes is a guide for anyone who identifies as Multiracial or antiracist—and for everyone seeking the confidence and community needed to build a healthier, more inclusive society.

Early praise for Multitudes…

  • As a public health leader, I’ve spent my career asking who gets left out and why. Multitudes answers that question for thirty-four million Multiracial Americans who have been rendered invisible by the very systems meant to serve them. Dr. Karabi Acharya understands what too many of us in public health are only beginning to reckon with: that belonging is not a soft idea. It is a health issue. When people cannot see themselves in our data, our institutions, or our national story, it causes real harm. When our public health institutions cannot see Multiracial people, their needs remain unaddressed. This book names that harm with precision and compassion and then, crucially, shows us the way forward. Multitudes belongs in the hands of every leader serious about building a healthier, more equitable America.”

    — Dr. Richard Besser, former Acting Director of the CDC and President and CEO of the Robert Wood Johnson Foundation

  • “For too long our frameworks for understanding race have engaged in their own form of othering—flattening identity and leaving millions of Multiracial Americans outside the circle of concern. Multitudes helps us see that this is not simply a gap in our data, but a failure of belonging. Dr. Acharya invites us to recognize Multiracial people not only as those who have been othered, but as vital bridgers—pointing us toward the deeper work of seeing and valuing our full humanity in one another. This is an important contribution to the ongoing project of building a society where everyone belongs.”

    —john a. powell, Director of the Othering & Belonging Institute and author of Belonging without Othering and The Power of Bridging

  • "I grew up Multiracial in America — the son of a Jamaican father and a German-American mother — and I know firsthand what it costs to exist between categories that the world insists are separate. That experience of not quite belonging, of being visible in your complexity but invisible in the systems around you, is not merely personal. It has consequences for your health, your community, and your sense of what is possible. Multitudes is the first book I have read that names that cost with the full weight of public health evidence behind it — and then points us toward something better. Dr. Acharya understands that belonging is not a soft idea. It is a human necessity. And for thirty-four million Multiracial Americans, it has been systematically withheld. This book is long overdue."

  • What if the problem isn’t who you are, but the categories you’re given? Karabi Acharya blends moving personal narrative and sharp social analysis to explore life between identities--and to imagine new ways of belonging in a world that resists simple labels.

    —Edward F Fischer, Vanderbilt University, author of The Good Life

  • “Multitudes shines a bright light on a topic that must be addressed if we are to ever effectively disrupt racism in the United States- Multiracial identity and belonging. Acharya beautifully weaves personal stories with research and social-historical context in a way where any mixed race reader will instantly feel affirmed. This book is a healing balm — and an empowering call to action — for Multiracial people and anyone else who is troubled by who gets to belong under the current racial caste system.”

    —Raina LaGrand, Founder, Mixed Race Belonging

  • "Social disconnection is one of the most serious public health crises of our time. As someone who is Multiracial, I know firsthand how the experience of somehow fitting in everywhere and nowhere at the same time can be incredibly lonely and isolating. The experience of being unseen, of existing between boxes—arbitrary categories created to divide and oppress - has consequences for our health, our communities, and our sense of self. Multitudes weaves together research with personal stories to illuminate this experience. Dr. Karabi Acharya names what so many of us have felt but rarely seen reflected in data or policy: that Multiracial Americans face a distinct epidemic of isolation driven by systemic erasure, not personal failing. This book is both a validation and a road map for change."

    — Edward Garcia III, Founder, Foundation for Social Connection; Co-founder, Global Initiative on Loneliness and Connection

  • “Karabi Acharya has written the kind of book that makes you pause mid-sentence because she just described something you thought only you felt. From the anxiety of checking a box on a form that was never designed for you to her reimagining of something as fundamental as the right to your own name, Multitudes captures the full weight of navigating complex identity with honesty, heart, and intellectual clarity. Readers who have spent their lives between categories will finally find recognition here.”

    —Dr. Shawna M. Gann, Author of Mixed Signals: The Multiracial Case for Civility and Belonging at Work
