One of the most practical things you can do from the outside is help your loved one get ready for a world that runs on numbers, screens, and systems they may not have seen in years. This guide is for you — the family member, partner, or friend on the outside — and it covers both what to teach and how to teach it.

Why This Matters More Than You Think

Digital literacy has always been on our resources page, but the conversation needs to go deeper. It’s not just about learning to use a smartphone again. It’s about being able to read and question the information that shapes your loved one’s daily life — inside and after release.

We talk a lot about reentry barriers: housing, employment, transportation. But there’s a quieter barrier that doesn’t get named as often: not being able to read the numbers. Not being able to spot when a statistic is misleading, when a job offer’s pay math doesn’t add up, or when a policy document is written to confuse rather than inform.

That’s data literacy. And it’s a survival skill.

The National Picture

This isn’t a small problem. The OECD’s Survey of Adult Skills found that 34% of U.S. adults — roughly 1 in 3 — scored at or below Level 1 in numeracy. That means they can handle very basic math, but struggle when tasks require multiple steps or reading information in tables and charts. U.S. government data from PIAAC also shows that the share of adults performing at the lowest literacy levels actually increased between 2017 and 2023.

Inside carceral settings, the gap is real. The most comprehensive national snapshot we have — the 2003 National Assessment of Adult Literacy Prison Survey — found that 39% of male inmates scored at the Below Basic level in quantitative literacy. That data is over 20 years old, and there hasn’t been a comparable national study since, which itself says something about how much this population is counted and resourced.

The point isn’t to shame anyone. The point is: the systems your loved one has to navigate — parole requirements, job applications, benefit forms, phone account charges, grievance processes — all run on data. The more equipped they are to read it critically, the more power they have.

Part 1: Data Literacy — The Numbers Behind the System

You don’t need to be a mathematician to teach this. You need five concepts. Here’s how to explain each one in a letter, a visit conversation, or a printed handout you mail in.

Lesson 1: Counts Are Not Rates

When an institution says “we had 50 incidents this quarter,” that number means nothing without knowing the population. 50 incidents in a facility of 100 people is very different from 50 incidents in a facility of 2,000 people.

How to explain it: “If someone told you 10 people in your dorm got sick, you’d want to know how big the dorm is, right? Is that 10 out of 15, or 10 out of 200? The count alone doesn’t tell you anything.”

Why it matters for reentry: Employment ads say “we hired 500 people last year.” That’s a count. What’s the application-to-hire rate? What percentage of applicants with records were hired? Those are the questions worth asking.

Lesson 2: Always Ask “Out of How Many?”

This is the denominator question, and it is the single most powerful thing you can teach someone to ask.

“Recidivism is down.” Compared to when? Using which definition of recidivism? Over what time window — one year, three years, five years? The Marshall Project has written extensively about how recidivism statistics are routinely misrepresented because the definitions and time windows shift depending on who’s making the argument.

How to explain it: “Every time you hear a stat, ask: out of how many? And compared to what? Those two questions will catch 80% of misleading numbers.”

Why it matters: When your loved one is navigating parole conditions, program requirements, or legal documents, they’ll encounter statistics used to justify decisions. Knowing to ask “compared to what?” is a form of self-defense.

Lesson 3: “Percent Change” Can Be a Trick

“A 50% reduction in fees” sounds huge. But 50% of what? If a commissary item went from $2.00 to $1.00, that’s a 50% reduction — and $1.00 in real savings. If a phone rate went from $0.04 to $0.02 per minute, that’s also a 50% reduction — but only $0.02 in real savings per minute.

Research on risk communication consistently shows that people make better decisions when they see absolute numbers — “2 out of 100 people” — rather than relative comparisons like “a 50% increase in risk.” The percentage framing is often chosen precisely because it sounds bigger or smaller than the reality.

How to explain it: “Whenever someone uses a percentage to describe change, convert it back to real numbers. Ask what the original number was, and what the new number is. That’s the honest version.”

Why it matters for reentry: This shows up in job offer pay discussions, benefit calculations, fee structures for halfway houses, and financial products marketed to people who are newly released.

Lesson 4: Averages Don’t Tell the Whole Story

“The average wait time for an ID is 3 weeks.” But what if most people wait 1 week, and a handful wait 4 months? Those outliers drag the average up. The median — the middle value — would tell a more honest story.

How to explain it: “If five people in a room make $20,000, $22,000, $25,000, $28,000, and $500,000 a year, the average income is over $100,000. But four out of five people make under $30,000. The average is technically accurate and completely misleading.”

Why it matters: Reentry programs, housing wait times, and job placement stats often use averages that don’t reflect what most people actually experience.

Lesson 5: Charts Can Lie If You Don’t Check the Axes

A graph where the y-axis starts at 90 instead of 0 will make a tiny increase look enormous. A timeline that starts in a cherry-picked year will make a trend look dramatic when it’s actually minor. These aren’t mistakes — they’re choices.

How to explain it: “Before you believe a chart, check two things: where does the y-axis (the side) start, and what years does the x-axis (the bottom) cover? If the side doesn’t start at zero, ask yourself why.”

Why it matters: Your loved one will encounter data visualizations in news, advocacy materials, and documents from institutions. Being able to spot a manipulated chart is a form of media literacy.

Part 2: The One-Page Tracking Template

One of the most practical applications of data literacy is learning to document systematically. A grievance that says “they keep doing this” is weak. A grievance that says “on March 3, March 10, and March 17, I submitted medical requests that were not acknowledged within the 72-hour window required by policy” is strong.

Help your loved one set up a simple tracking system. You can mail this template in, write it in a letter, or ask them to copy it out.

Date	What Happened / What I Requested	Who I Told / Where I Submitted It	Their Response	Outcome / Follow-Up Needed

Tips for using it:

• Be specific with dates — not “last week” but “March 3, 2026”
• Write what actually happened, not how you felt about it (feelings go in a journal; this document is for evidence)
• Track outcomes even when they’re “no response” — that’s data too
• If something repeats, you now have a pattern, not just a complaint

Part 3: Digital Literacy for After Release

The existing digital literacy guide on this site covers the basics well — libraries, free courses, job platforms. Here we want to add the layer that often gets skipped: critical thinking about digital information, not just how to use the tools.

The Three Habits That Matter Most

1. Verify before sharing or acting. The speed of digital information means misinformation travels faster than corrections. Teach your loved one to ask: Is this from a primary source — the actual organization, the actual document — or is it secondhand? Can I find one other credible source saying the same thing? If something feels designed to make you angry or scared, slow down.

2. Understand what data you’re giving away. Every app, every account, every free service collects data. That’s not necessarily a reason not to use them — but it’s a reason to be intentional. For someone on parole or probation, this matters more: location data, browsing history, and social media activity can all be accessed under certain legal circumstances. This isn’t paranoia; it’s information.

3. Read the numbers in news and social media the same way you’d read them in a document. When a headline says “crime is up 40%,” ask: up from what baseline? In what city? What type of crime? Over what period? The same five-lesson framework from Part 1 applies to everything your loved one reads on a screen.

Part 4: How to Teach This From the Outside

You can’t hand someone a laptop through visiting glass. But you can do a lot more than you might think.

In letters: Write out one concept per letter. Use a real example from something you’ve both experienced — a commissary price change, a phone rate, a news story you both heard about. Ask them to respond with their own example. That back-and-forth is active learning.

In calls: Play “what’s the denominator?” together. When either of you hears a statistic in conversation or on the news, practice asking the follow-up questions out loud.

In visits: Bring in a printout (if allowed) of a simple chart or statistic — something neutral — and work through it together. Practice spotting what information is missing.

When they’re released: Don’t just hand someone a phone and a password. Sit with them. Walk through how the apps work, what data they’re sharing, how to evaluate a job posting’s legitimacy, how to spot a scam. This transition period is when people are most vulnerable to predatory financial products and misinformation.

A Note on Why We’re Adding This

At Chapters and Chains, our whole premise is that connection across walls is possible — and that the people on the outside have more power to support reentry than they often realize.

Data literacy isn’t a luxury skill. It’s the difference between being able to advocate for yourself or being talked out of your own experience by someone with a spreadsheet. It’s the difference between understanding what a job offer actually pays and signing something that hurts you. It’s the difference between a grievance that gets dismissed and one that can’t be ignored.

You don’t have to be an expert to teach this. You just have to be willing to learn it alongside the person you love.
