Podcast Statistics: Growth and Demographic Data [November 2021]
Every year, media groups like Statistica, Triton Digital, and Edison Research run digital media surveys to measure trends, understand listener behavior, and track podcast growth worldwide.
We update this post monthly with the latest podcast statistics so you can stay updated on the industry and make informed decisions about your own podcast.
How popular are podcasts?
In the early 2000s, only 22% of the adult population in the United States was aware of podcasting.
In 2021, 78% (222 million) of Americans are familiar with the medium—up 3% from 2020—and more than one-third (104 million) of Americans listen to podcasts regularly.
According to Edison Research, 41% (116 million) listened to a podcast in the last month, and 22% are weekly podcast listeners.
Podcasts are popular in part because of the convenience factor; the industry grew alongside the advent of smartphones, smart speakers (Amazon Alexa, Google Home, etc.), and in-dash entertainment systems.
Now that 88% of Americans own a smartphone, it's never been easier to listen to podcast content in the car or on the go with a portable device.
The pandemic also increased smart speaker ownership, which grew by over 22% as more people worked from home.
Despite COVID, and in part because of it, podcasting experienced unprecedented growth and podcast audiences diversified.
Who listens to podcasts?
Historically in podcasting, white people made up the majority of listeners, but this is starting to shift, along with the age and gender gap of previous years.
While podcast consumers are still predominately white, there is more diversity in 2021 among Hispanic, Latino, and black listeners, closely mirroring the diversity of the U.S. population.
Currently, 57% of U.S. podcast listeners are white, 13% are African American, 16% are Hispanic, 4% are Asian, and 10% identify as other.
Broken down by country, the United States accounts for 47.9% of podcast listeners, followed by the United Kingdom with 6.3%, and Canada with 5.0% (you can see how other countries rank in the lineup here).
People ages 12-34 make up 66% of podcast fans within America, and podcast listenership declines as age increases.
Still, about half of listeners between ages 35-44, and one-fifth of listeners over age 65, listen monthly.
Along with more diversity, Infinite Dial's 2021 survey also showed a closing of the gender gap in podcasting with 43% men and 39% women.
Podcast listeners have always been an educated group, and that's still the case.
Over 66% have a college degree (bachelor's or higher) and an average annual household income of $75,000 or more.
International podcast statistics
While other countries have lower listening stats than the U.S., most see numbers rise every year.
As of 2020, 18% of adults in the U.K. listen to podcasts every week, 4% more likely than in 2019.
According to a 2019 Infinite Dial™ survey, 36% of Canadians over 18 years old listen to podcasts every month—up from 28% in 2018.
A little over half of Italians between ages 18 and 34 have listened to a podcast in the last year.
Interestingly, music programs are the preferred podcast genre on 45% of Italian listeners, second to news programs.
In Australia, podcast awareness went up 4% in 2020, and 25% of the country listened to a podcast in the last month—an increase of 3%.
According to a study by audio technology blog Voxnest, Podcasting is growing fastest in the following countries:
- Chile (83.9%),
- Argentina (55.3%),
- Peru (49.1%),
- Mexico (47.8%), and
- China (43.6%).
Where do people listen to podcasts?
Currently, 62% of Americans have listened to audio in a car using their cell phone, and 18% of people ages 18+ own a vehicle with a smart entertainment system, making it simple to fit podcast listening into daily routines.
Not surprisingly then, a 2019 study showed over one-fourth of podcast listeners consume podcast content while driving and commuting to work.
Regardless of where people listen, most podcast consumers stream content using their smartphones as an audio source and listen to episodes via a major podcast app like Apple or Spotify.
Most popular podcast directories
As of November 2021, Spotify holds the number one spot with 31.2% of all podcast listeners (28,475,576 podcast downloads)—up from 25% in 2020.
Spotify grew its podcasting platform significantly in the last year with after JRE catalog deal, accounting for many new listeners.
Apple Podcasts is number two in download numbers, with 31.1% of podcast users and 28,354,842 downloads.

Listener behavior & trends
According to a 2018 study by Nielsen, 94% of podcast listeners are active on every social media channel (13% more than the entire population).
Podcast listeners tend to be a highly engaged audience, so it makes sense that 69% of respondents say podcast ads increase their awareness of products, brands, and services.
Podcast listeners are also more likely to follow brands on social media and own a smart speaker (like HomePod mini or Amazon Echo).
Podcast listeners tend to listen to more audio in general. Even light podcast consumers listen a total of 10 hours and 13 minutes of radio each week—an increase of 43 minutes more than the average American.
Heavy podcast consumers listen to radio 65 minutes more than most Americans. And on average, podcast listeners consume seven different shows every week.
And while other mediums tend to fight hard to keep viewership or listenership, podcast listeners tend to be highly engaged, and 80% listen to all or most of every podcast episode they start.
The most popular podcast genres and shows
According to a 2020 statistics study, 22% of podcast listeners in the United States prefer comedy as a genre.
News is the second most popular podcast genre, followed by true crime, sports, and health/fitness.

Duration of podcast episodes:
- Less than 10 minutes: 13%

Podcast listeners have many ways they find new content, but a few are more common than others.
According to a recent Buzzsprout survey, 52.6% of listeners find new podcasts by searching a podcast directory like Apple Podcasts.
22.1% ask a friend for podcast recommendations, and 14.5% get suggestions from their favorite podcast host.
Other options were:
- Search Google (5.5%)
- Follow podcast guests (3.5%)
- Ask on social media (1.7%)
The results of this survey highlight the importance of the two leading podcast marketing strategies: quality SEO and word of mouth.
Podcast advertising trends and performance
Because of podcasting's intimate and niche nature, advertisers can get their products in front of highly engaged audiences.
Simple, host-read ads within podcast episodes are refreshing to listeners who are becoming increasingly deaf to other forms of advertising.
According to Midroll, 60% of podcast listeners have bought something from a podcast ad—a significant amount any way you look at it, but even more so due to the rising ineffectiveness of other advertising mediums.
People tend to be loyal to the podcasts they listen to, so it's no surprise that 72% of listeners who have listened to a podcast for four or more years have purchased a sponsored ad.
Even if listeners haven't yet bought anything from an ad, 81% say they pay attention to them more than they do to radio, TV commercials, or billboards, and even digital ads on social media.
Podcasting remains a highly effective and lucrative marketing tool for large companies, small brands, and entrepreneurs looking to grow their reach.
The future of podcasting
Industry experts expect podcasting to grow significantly in 2021 as on-demand audio increases in popularity.
Current estimates project that listeners in the U.S. could increase from 75.9 million to 100 million listeners in the U.S. by 2024.
Just three years ago, in 2018, 44% of Americans had listened to a podcast.
In 2021, that number rose to 58% and is projected to rise steadily in 2022 as podcast popularity increases and becomes more and more mainstream.
As more podcasters move into the space and create more varied content, we'll likely see not only more listeners but more diversity, too.
While podcasters in the 12-34 age group still dominate the landscape, they're 7% more likely to listen in 2021 than last year.
