The biography genre: why we never stop reading about other people's lives
Demand for biographies and memoirs is not just stable, it is structurally growing. According to Wordrated's review of Meminto (2025), the global non-fiction book market was valued at $14.02 billion in 2022 and is projected to reach $16.61 billion by 2026. Within this segment, biographies and autobiographies are the clear leader: in the US they hold the top spot in the hardcover non-fiction category on Amazon, ahead of self-help and religious literature.
NIQ's 2025 analytics add more detail: in the UK, auto/biographies became the best-selling non-fiction genre in print for 2024. Together with self-help/popular psychology, they accounted for just over 30% of all non-fiction purchases, and in audiobooks that share jumped to 45%. The 25-44 age group is the main driver: this demographic bought 42% of all non-fiction in 2024 and 54% of audiobooks.
What is behind the numbers? People are not paying for facts (facts are free on Wikipedia), they are paying for narrative, for the chance to live someone else's trajectory from the starting point to the outcome, to see the mechanics of decisions in context. And the market confirms this.
What the numbers say: audience, formats, and shifts
The genre is undergoing not a quantitative but a qualitative shift. Here are the key data points from 2024-2025 reports:
- Print dominance, with a caveat. 77% of global book sales still come from print (Statista, via Meminto), but in non-fiction the digital share hit a historic high in 2024, with print falling below three quarters for the first time.
- Audiobooks as the second engine. Audiobook segment revenue is projected to grow 27% over the next five years and reach $35.05 billion by 2028, with biographies among the most in-demand genres in audio (Meminto data (2025)).
- Young adult memoir is gaining momentum. Memoir sales in the young adult category showed 26% revenue growth over five years, despite an overall 17.9% drop in units sold in 2021 (a post-COVID correction).
- Self-publishing goes mainstream. More than 60% of memoir authors in recent years choose self-publishing; the barrier to entry has fallen thanks to accessible publishing tools.
- Third most translated in the world. Biographies are the third most translated genre in the world: these books cross language and cultural barriers faster than most other categories.

What sells: bestsellers and their economics
The commercial landscape for biographies is defined by several heavyweight titles. A Wordrated (2025) summary gives this picture of confirmed sales:
Book | Author | Year | Copies sold (estimate) |
|---|---|---|---|
An Autobiography | Agatha Christie | 2012 | >10 million |
A Promised Land | Barack Obama | 2020 | >5 million |
The Autobiography of Benjamin Franklin | Benjamin Franklin | 1791 | >5 million |
Becoming | Michelle Obama | 2018 | >4 million |
Educated | Tara Westover | 2018 | >2 million |
Born a Crime | Trevor Noah | 2016 | >2 million |
Spare | Prince Harry | 2023 | UK pre-order record |
Note the spread: Franklin, 18th century, Christie, mid-20th century, Obama and Noah, the last decade. The genre is not tied to novelty, it is tied to the power of the story. At the same time, Prince Harry's "Spare" (2023) set a pre-order record in the UK and topped the charts in Ireland, Italy, and New Zealand, a clear demonstration that an author's media profile converts into instant demand.
The trend toward "unheard voices" deserves separate attention: over 30% of new biographies published in 2023 focused on people from underrepresented groups. The market is expanding not so much in depth (new books about Churchill) as in breadth (books about people who were not written about before).
⁉️🤔 Frequently asked questions about the biography genre
What is the difference between a biography, a memoir, and an autobiography?
A biography is the story of a person's life written by another author (research, archives, interviews). An autobiography is a book where the author tells the story of their entire life themselves. A memoir is a narrower format: the author describes a specific period or event (for example, "Into Thin Air" by Jon Krakauer, a memoir about a single Everest expedition).
What are the best-selling biographies in history?
According to the Wordrated summary, the absolute leader is "An Autobiography" by Agatha Christie (over 10 million copies). It is followed by "A Promised Land" by Barack Obama and the autobiography of Benjamin Franklin (5+ million each). Michelle Obama's "Becoming" has 4+ million, and "Educated" by Tara Westover and "Born a Crime" by Trevor Noah have 2+ million each.
Why are biographies so popular in audio format?
An audiobook imitates oral storytelling, the natural format for a life story. Many memoirs are narrated by the authors themselves (Michelle Obama, Trevor Noah), which adds intimacy. According to NielsenIQ analytics, in the UK, auto/biographies + self-help accounted for 45% of all audiobook purchases in 2024.
Is it worth writing a memoir if I am not a celebrity?
Yes. The market is moving toward diversity of voices: over 30% of new biographies in 2023 focused on people from underrepresented groups. In addition, 60% of memoir authors today go through self-publishing, so the publishing infrastructure no longer requires a media name. The story of an ordinary person in a unique context (profession, era, region) is often more valuable than a celebrity name without substance.
How has the biography market changed with the arrival of digital formats?
Fundamentally. Digital nonfiction reached a historic high in market share in 2024, and print fell below 75% of purchases for the first time. Audiobooks nearly doubled their share over five years. But the print biography remains a status product: hardcover + photographs + family trees cannot be reproduced in ePub. The genre gains from multi-format availability rather than losing from it.

Three reasons the genre holds its ground
First, the universality of the format. A biography works as entertainment (scandals, intrigue, behind the scenes), as a business case (strategic decisions, crisis management, market entry), and as psychological training (overcoming adversity, resilience, motivation). One product, three audiences.
Second, trust in the document. In the age of AI content, readers increasingly look for a factual foundation. A biography with references to archives, letters, and interviews is one of the few formats where the author cannot completely fabricate the material without reputational consequences. This gives the genre a "credibility premium" in the eyes of a paying audience: readers aged 25-44, who, according to NIQ, buy 42% of all nonfiction and 54% of audiobooks.
Third, an endless supply of material. Every year new figures emerge and old ones are reinterpreted. After 2020, a wave of memoirs by doctors and scientists. After 2022, books about displaced people and volunteers. After 2024, autobiographies of AI entrepreneurs. The genre is a mirror, and a mirror always has something to reflect. Tellingly, biographies remain the third most translated genre in the world precisely because the local story of one person in one country often turns out to be universal for a reader on another continent.

How to write a biography: a step-by-step plan
💡 Quick overview:
- Working with sources: archives, interviews, correspondence, diary entries
- Chronological framework and choosing a dramatic arc
- The text: voice, pace, balance of fact and narrative
- Legal compliance and publication
- Promotion: audio format, translations, platforms
The research stage takes up between a third and half of the total time spent working on a biography. This is not about reading one book about the subject, but about systematic collection: state archives, private letters (if the heirs have opened access), newspaper files of the era, oral interviews with contemporaries. For a 300-page biography, drawing on 20-40 sources is considered normal, of which 5-7 are primary documents (letters, diaries, archival records). The depth of research directly determines the value of the book: the reader pays for a picture assembled from details they will not find on Wikipedia.
Composition is the next hurdle. The "born, studied, married, died" chronology does not sell. Strong biographies are built around a dramatic arc: either "the road to greatness" (from poverty to success), or "a tragic rise and fall," or "a person against the backdrop of an era." The choice of arc determines which events make it into the book and which are left out. A beginner's mistake is trying to fit everything in.
Working with the text is the third stage. Biographical style requires balance: literary enough that the reader does not get bored by dates, and documentary enough that a specialist does not accuse the author of invention. More than 60% of memoir authors now publish independently, which means competition happens at the level of the text, not the publishing brand.
After the manuscript comes the legal stage. For a biography of a living person, written consent is needed (or at least the absence of objections); in jurisdictions with strict privacy laws (EU, UK) this is critical. For historical figures the risks are lower, but checking quotes and facts is still mandatory.

Where the genre is heading: forecast to 2028
The biography market rests on three pillars of growth.
Audio and multiformat. Audiobooks are the fastest-growing segment in nonfiction: up 27% over five years (Meminto forecast). Biographies in audio offer something other genres cannot: a sense of presence, especially if the author reads them personally. By 2028, a significant share of new biography releases is expected to come out simultaneously in print, ePub, and audio, with author narration as the standard rather than an option.
Globalization through translations. Biographies are the third most translated genre in the world. For an author this means: a book about a local figure (an Indian entrepreneur, a Brazilian politician, a Nigerian writer) has a chance to reach an international reader. Translations are ceasing to be a bonus and becoming a business strategy: Michelle Obama's "Becoming" has been translated into 30+ languages, Tara Westover's "Educated" into 45+.
Niche subgenres. Beyond the classic "great person" format, hybrids are growing: business biography (the story of a company through the story of its founder), travel memoirs (geography as the framework of a life story), graphic biography (the comic format, growing in the YA segment). Each of these offshoots expands the genre's audience without competing directly with traditional biography. A separate phenomenon is biography in podcast format: serialized audio stories of 30-40 minutes each are racking up millions of listens, especially among the 25-34 audience, which, as we noted above, is already the main consumer of nonfiction.
To sum up: in 2026, biography is not a bookshelf with leather spines, but a living, multiformat, globally traded category with growing demand. If you are an author, the moment to enter is favorable: publishing barriers have fallen, and readers are willing to pay for a well-told story.
Conclusion
Biographies and life stories of great people are a genre that is not fading into the shadows, but reassembling itself for the new media environment. The figures from the Meminto review and the NielsenIQ report show a consistent picture: print holds its ground, audio is growing explosively, the audience is getting younger, and geographic reach is expanding through translations. If you have long wanted to read a biography of a person who inspires you, start today: in audio on your commute, in print in the evening, or in ePub on your phone. And if you have a story of your own worth telling, the infrastructure for it has never been more accessible. The genre is waiting for new voices, and each of them can find its reader.
