A statistic is a promise of proof. The purpose of a statistics component is to give a website visitor a quick, credible reason to keep reading, apply, give, or get in touch.
Used well, a few strong numbers build trust and make your story concrete. Without best practices, they become decoration that visitors skim past or, worse, doubt. The more relevant, specific, and verifiable your statistics are, the more effective they will be.
Before choosing statistics for your website
Start with your audience
Ask what a prospective student, parent, donor, or collaborator needs to believe before they take the next step, then pick numbers that answer that question.
Focus on outcomes over inputs
Results (graduates employed or in graduate school, students doing research, internships completed) persuade more than totals that only describe size (number of buildings, number of courses).
Think of what is specific and checkable
A precise, sourced figure with a date reads as more trustworthy than a round, unsupported claim.
Pick the right statistics for your page
Match the number to the page goal
A degree program page might feature job placement and research participation. A giving page might feature scholarship dollars awarded. A department home page might feature faculty-to-student ratio or study abroad participation.

Choose numbers a visitor can picture
"1 in 3 majors completes an undergraduate research project" is easier to grasp than a large aggregate with no scale.
20:1
Look for what is distinctive
If every university could make the claim, it will not set you apart. Prioritize facts that are true of your unit specifically.

Per U.S. News and World Report 2026
Use 3 or 4 statistics at most per page
Fewer numbers get more attention. If you have ten good statistics, spread them across pages where each one supports the surrounding content.
Mix the types
Pair a hard outcome (percentage, dollar amount) with a human-scale number (class size, ratio) to give a fuller picture.

Pick numbers you can keep current
If you cannot commit to refreshing a figure on a schedule, choose something more stable or leave it out.

Use official sources
Pull figures from the CLAS Dean's Dashboard, the Office of the Registrar, the Office of the Executive Vice President and Provost, or your own program records so they match what the university reports elsewhere.

Know when a story works better
Some of your best evidence is a person, not a number. Consider a student or alumni profile instead of, or alongside, a statistic.
Avoid these practices
Don't use vague or inflated claims.
Avoid "world-class," "countless," or "thousands of opportunities" with no figure behind them.
TOP-NOTCH
Don't publish a number you cannot source.
If you can't point to where it came from, don't use it.
100 s
Don't make ranking claims without detail.
Name the ranking, the organization, the category, and the year, and make sure you have the right to use it.
# 1
Don't overload the component.
Five or more numbers compete with each other and none sticks.

Pre-publishing checklist
- Does this statistic support the goal of this page?
- Can you name the source and the year of the data point?
- Is it clear who or what is being counted?
- Would a skeptical visitor find it believable?
- Do you know when you will review it next?
- Does the label make sense without seeing the layout of the page?
