One Mission. Five Platforms. A Stronger Reach.

If you're looking at social media from a marketing, recruitment, community engagement, or Marine Corps League perspective, the biggest mistake is treating all platforms as interchangeable.

Each platform has a different audience, mindset, content preference, and reason for being there.

The latest comprehensive Pew Research data is based on U.S. adults surveyed in 2025. YouTube and Facebook remain the two broadest-reach platforms, while Instagram, TikTok, Snapchat and Reddit skew substantially younger.

SOCIAL MEDIA DEMOGRAPHIC BREAKDOWN — 2026

Platform	Typical age	Audience profile	What users go there for	Best content
Facebook	30–64	Broadest adult audience	Community, friends, local information, events	Photos, stories, events, community news, video
YouTube	18–64+	Extremely broad	Learning, entertainment, how-to, documentaries	Long/short video, interviews, tutorials
Instagram	18–44	Younger, visual, female-leaning	Inspiration, lifestyle, identity, discovery	Reels, photos, Stories
TikTok	18–34	Gen Z + Millennials	Entertainment, discovery, personality	Short vertical video
LinkedIn	25–54	Professionals, business owners, executives	Career, business, networking	Professional stories, leadership, accomplishments
Reddit	18–44	Younger, discussion-oriented, male-leaning	Communities, expertise, opinions	Discussions, AMAs, niche information
Snapchat	13–34	Very young	Friends, casual communication, entertainment	Short video, Stories
Pinterest	25–54	Female-leaning	Ideas, planning, inspiration	Images, guides, projects
X	18–49	News/politics/current-events oriented	Real-time information, commentary	Short commentary, news, opinions
Nextdoor	30–65+	Local/community	Neighborhood information	Local news, events, safety, recommendations
WhatsApp	18–49	Broad, especially multicultural/international	Private communication and groups	Direct messages, groups, announcements
Threads	18–44	Instagram-connected audience	Conversation and commentary	Short text, conversation
Truth Social	35–65+	Politically conservative audience	Politics/current events	Commentary, political content
Bluesky	18–49	Smaller, tech/news-oriented	Conversation and alternative social network	Text, links, discussion

THE MOST IMPORTANT NUMBERS

Among U.S. adults, Pew's 2025 research found:

Platform	U.S. adults using it
YouTube	84%
Facebook	71%
Instagram	50%
TikTok	37%
WhatsApp	32%
Reddit	26%
Snapchat	25%
X	21%
Threads	8%
Bluesky	4%
Truth Social	3%

That means something important:

Don't confuse "youngest platform" with "best platform."

For reaching the largest possible adult audience, Facebook and YouTube are still extremely powerful.

1. FACEBOOK — THE COMMUNITY PLATFORM

Typical demographic: 30–64, but with meaningful usage from virtually every adult generation.

Pew reports Facebook usage of:

• 18–29: 68%
• 30–49: 80%
• 50–64: 74%
• 65+: 57%

Women also report higher usage than men: 78% vs. 63%.

User mindset

Facebook users are often asking:

• "What's happening in my community?"
• "What's happening with my friends?"
• "What's the event?"
• "What happened?"

Excellent for

• Local organizations
• Veterans organizations
• Community events
• Fundraising
• Membership recruitment
• Family-oriented content
• Event promotion
• Historical content
• Photos
• Testimonials
• Local news

MCL application

Facebook should probably remain the MCL's primary community platform.

It's particularly strong for reaching:

Gen X + Millennials + Boomers + families of veterans.

2. YOUTUBE — THE AUTHORITY PLATFORM

YouTube is different because people don't necessarily think of it as "social media."

They think:

• "I want to learn something."
• "Show me how."
• "Tell me the story."

Pew finds 84% of U.S. adults use YouTube, including 95% of 18–29-year-olds and 64% of those 65+.

Best content

• Interviews
• Podcasts
• Veteran stories
• History
• How-to
• Training
• Documentary-style videos
• Long-form storytelling
• Shorts

MCL opportunity

This is potentially underutilized by veterans organizations.

Instead of:

"Come join the Marine Corps League."

Create:

• "What happens when a Marine leaves the Corps?"
• "5 things I wish I knew after leaving the Marine Corps."
• "Where do Marines go after the Corps?"
• "Why veterans organizations are disappearing."

That's content first, recruitment second.

3. INSTAGRAM — THE IDENTITY PLATFORM

Instagram is heavily concentrated among younger adults.

Pew reports usage of:

• 18–29: 80%
• 30–49: 62%
• 50–64: 40%
• 65+: 19%

Women also use it more than men: 55% vs. 44%.

Instagram is less:

"Here's our organization."

and more:

"Here's who we are."

Best content

• Reels
• Faces
• Behind-the-scenes
• Uniforms
• Events
• Humor
• Emotional stories
• Veterans doing things
• Young members
• Families
• Community involvement

MCL opportunity

Show people, not meetings.

Bad:

"Monthly Detachment Meeting — 7 PM."

Better:

"Three Marines. Three generations. One Corps."

Then show the members.

4. TIKTOK — THE DISCOVERY PLATFORM

TikTok is heavily younger, although the stereotype that "TikTok is only teenagers" is increasingly wrong.

Pew reports usage of:

• 18–29: 63%
• 30–49: 44%
• 50–64: 30%
• 65+: 12%

And 24% of U.S. adults say they use TikTok daily, rising to roughly half among 18–29-year-olds.

User mindset

TikTok is:

• "Surprise me."
• "Teach me something."
• "Make me laugh."
• "Show me something interesting."

Best content

15–60 second videos. Examples:

• Marine myths
• Marine Corps history
• Uniform trivia
• "Did you know?"
• Veteran humor
• Boot camp stories
• Things only Marines understand
• Before/after military service
• Veteran transition stories

MCL opportunity

TikTok is potentially one of the best platforms for reaching post-9/11 veterans and younger family members.

5. LINKEDIN — THE PROFESSIONAL PLATFORM

This is the platform people frequently overlook.

LinkedIn isn't primarily about veterans. It's about:

Career + business + leadership + credibility.

It's particularly useful for:

• Business owners
• Executives
• Professionals
• Government
• Nonprofits
• Sponsors
• Grant partners
• Corporate relationships

Historically, adults 30–49 have been particularly strong LinkedIn users. Pew's 2023 data showed 40% usage among that age group versus about 30% among 18–29 and 50–64.

MCL opportunity

Don't primarily use LinkedIn to recruit members. Use it to recruit:

Sponsors + partners + community leaders + volunteers.

Example:

"Our detachment partnered with three local businesses to provide transportation for veterans attending our community event."

That's a LinkedIn story.

6. REDDIT — THE CONVERSATION PLATFORM

Reddit is fundamentally different.

People don't necessarily want to be marketed to. They want:

Answers + opinions + experiences + communities.

Pew reports Reddit usage of:

• 18–29: 48%
• 30–49: 35%
• 50–64: 16%
• 65+: 6%

Men also use Reddit somewhat more than women: 29% vs. 23%.

MCL opportunity

Extremely interesting for:

• Veteran questions
• Marine Corps history
• Transition discussions
• Benefits information
• Equipment
• Marine stories
• "What was your experience?" conversations

But don't go into Reddit with an advertising mentality.

7. SNAPCHAT — VERY YOUNG AUDIENCE

Snapchat remains strongly concentrated among younger users:

• 18–29: 58%
• 30–49: 31%
• 50–64: 13%
• 65+: 4%

It's particularly relevant for Gen Z.

For an MCL organization, I would consider Snapchat secondary, unless the organization is specifically trying to reach very young veterans or younger family members.

8. NEXTDOOR — THE LOCAL COMMUNITY PLATFORM

Nextdoor is interesting because its value isn't necessarily demographic.

Its value is:

GEOGRAPHY.

People use it because they want to know, "What's happening around me?"

That makes it potentially valuable for:

• Memorial events
• Community service
• Veteran assistance
• Parades
• Fundraisers
• Food drives
• Public ceremonies
• Volunteer opportunities

For a local MCL detachment, Nextdoor can punch above its overall national size because the audience is geographically concentrated.

9. X — THE REAL-TIME CONVERSATION PLATFORM

X has a smaller overall U.S. adult audience than Facebook, YouTube, Instagram or TikTok — about 21% in Pew's 2025 survey.

But its value is different. It's strong for:

• Breaking news
• Politics
• Military affairs
• Government
• Current events
• Journalism
• Commentary
• National organizations

Men report higher usage than women: 25% vs. 16%.

For an MCL national organization, X can be useful. For a local detachment, I'd rank it considerably lower.

THE BIG TAKEAWAY

If you're trying to reach younger veterans, don't simply ask:

"What social media platform do young veterans use?"

Instead ask:

What are we trying to accomplish?

Objective	Best platforms
Reach everybody	Facebook + YouTube
Reach Millennials	Facebook + Instagram + YouTube
Reach Gen Z	TikTok + Instagram + YouTube
Recruit younger veterans	Instagram + TikTok + YouTube
Reach established veterans	Facebook + YouTube
Promote local events	Facebook + Nextdoor
Build community	Facebook
Tell veteran stories	YouTube + Facebook
Build younger identity	Instagram + TikTok
Recruit sponsors	LinkedIn + Facebook
Reach business leaders	LinkedIn
Have serious discussions	Reddit
National military/news influence	X + YouTube

FIVE PLATFORMS, FIVE JOBS

There's an important distinction for an MCL strategy. Building on the earlier parts of this series, build the MCL social strategy around five different jobs, rather than trying to put the same post everywhere:

• FACEBOOK = Community
• INSTAGRAM = Identity
• TIKTOK = Discovery
• YOUTUBE = Authority
• LINKEDIN = Partnerships

That's a much more powerful framework than simply saying:

"We need to post more on Facebook."

ONE EVENT. FIVE PLATFORMS.

There is another major opportunity here: the same story can be repurposed across all five platforms, but the presentation should change.

For example, one MCL event could produce:

Platform	Content
Facebook	10 photos + event story + invitation
Instagram	30-second Reel showing Marines interacting
TikTok	20-second humorous/interesting moment
YouTube	3–5 minute story about the event and its impact
LinkedIn	Story about community partnership and veteran impact

That creates a content engine, rather than five separate social-media chores.

The underlying demographic data strongly supports this approach: Facebook remains unusually broad across generations, while Instagram, TikTok and Snapchat skew younger and YouTube reaches virtually every generation.
