Projected Aging Among People with HIV in the United States: A Modeling Analysis in 24 States
This modeling analysis of 24 US states projects that the median age of people living with diagnosed HIV will rise from 51 to 62 by 2040, with over half exceeding age 65, while highlighting significant state-level heterogeneities that necessitate tailored healthcare planning.

Imagine the United States' population of people living with HIV (PWDH) as a massive, long-running theater production. For decades, the cast has been getting older, but the show is just getting started. This paper is like a crystal ball that looks at the next 15 years of this show, specifically for 24 different "regional tours" (states) across the country.
Here is what the authors found, translated into everyday language:
The Big Picture: The Cast is Getting Older
The main story is simple: The audience and the actors are aging together.
Thanks to modern medicine, people with HIV are living longer, healthier lives. Because fewer people are dying from the virus, the "middle-aged" and "senior" sections of the crowd are getting bigger.
- In 2025: The "average" person in this crowd is about 51 years old.
- In 2040: That average age is projected to jump to 62 years old.
- The Surprise: By 2040, more than half of all people living with diagnosed HIV in these states will be over 65. That's the age where most people in the US start getting Medicare.
The "Two Different Shows" Analogy
The most interesting part of the paper is that this isn't happening the same way everywhere. The authors compared the HIV epidemics in different states to two very different types of neighborhoods:
- The Big City Neighborhoods (e.g., California, New York, Florida):
Think of these as bustling, older cities. The people living with HIV here are already older. The paper predicts these cities will get even older very fast. By 2040, the average age in California could be 71. It's like a retirement community that's already full and just getting more senior citizens every year. - The Small Town Neighborhoods (e.g., Arkansas, Alabama, Oklahoma):
These are like smaller towns where the crowd is still quite young. In these places, the average age might actually stay the same or even get slightly younger. Why? Because new, younger people are still joining the group at a rate that keeps the average age down. It's like a town where the high schoolers and young adults are still the majority.
Why Does This Happen?
The authors used a complex computer model (think of it as a very sophisticated weather forecast, but for people and viruses instead of rain and wind) to figure this out.
They found that the biggest factor is how fast new people are getting diagnosed.
- In the "Big City" states, new diagnoses are happening slower relative to the total number of people already living with HIV. So, the existing older crowd just keeps getting older.
- In the "Small Town" states, new diagnoses are happening faster relative to the total. This brings in a fresh wave of younger people, which keeps the average age from skyrocketing.
What Does This Mean for the "Theater"?
The paper suggests that the "stage crew" (healthcare systems, government programs like Medicare and Ryan White) needs to start packing different props for the next act.
- The Old Props: For a long time, the focus was on keeping the virus suppressed.
- The New Props: As the cast ages, they will need help with "age-related" issues. The paper notes that older adults with HIV are more likely to deal with heart disease, diabetes, kidney issues, and memory problems.
- The Challenge: The healthcare systems in the "Big City" states need to prepare for a massive influx of seniors who need help with these complex, older-person health issues. The "Small Town" states might not need to change their plans as drastically right now, but they need to keep an eye on the future.
The Bottom Line
The paper doesn't tell us how to fix these problems or what specific drugs to use. Instead, it acts as a map. It tells us that the landscape of HIV in America is changing. By 2040, the "typical" person living with HIV will be a senior citizen, but this shift will happen much faster in some states than in others. The message is clear: healthcare planners need to look at their specific state's map and prepare for the specific age group that will be walking through their doors in 15 years.
