If the healthy target never changes, then comparing yourself is not about hunting for a higher allowance at your age. It comes down to two things: seeing where your reading sits among people your age, and understanding how common high blood pressure becomes as people get older, so you know whether a reading is worth keeping an eye on.
Where Your Reading Falls: Blood Pressure Percentiles by Age
The most direct way to see how you compare is a percentile table. The figures below come from the National Center for Health Statistics' analysis of measured blood pressure in U.S. adults, which reports how readings are spread out within each age group. Find your age band, then see where your top (systolic) number lands.

Here is how to read it. Say you are 52 and your top number is 128. That is higher than at least half of people your age, but lower than the top quarter, whose readings start around 131.
Now look at the median for adults 60 and older: 133. A perfectly typical reading for that age group already falls in the Stage 1 hypertension range. That single number is the clearest illustration of why "normal for your age" and "healthy" are not the same thing.
Average Blood Pressure by Age and Sex

Two patterns stand out. The top number climbs with each age band, while the bottom number peaks in midlife and then eases back down. And women, who average lower readings than men through their younger and middle years, overtake them after 60, with an average top number of 139 compared with 133 for men.
These are the most recent national figures that report averages and percentiles by age group. They come from survey measurements taken in 2001–2008 and are broken into three broad age bands, so treat them as a general reference point rather than a precise benchmark for your exact age.
How Common High Blood Pressure Becomes With Age
The pattern is striking. Drawing on a 2024 CDC data brief covering 2021 through 2023, high blood pressure shows up in about 23 percent of adults aged 18 to 39, jumps to roughly 53 percent of those aged 40 to 59, and reaches nearly 72 percent of adults 60 and older. In plainer terms, that is about 1 in 4 younger adults, around half of midlife adults, and close to 3 in 4 older adults. Overall, just under half of U.S. adults — about 48 percent — have high blood pressure, with men somewhat more likely to be affected than women.

Earlier national data tell a similar story and add a useful detail about sex differences. In the 2017–2018 survey cycle, prevalence ran far higher in younger men than younger women — about 31 percent versus 13 percent among those under 40 — though that gap narrowed steadily with age until it nearly disappeared after 60.
What all of this means for you is reassurance of a particular kind. If your numbers are creeping up and you are in your fifties or sixties, you are in very large company, and high blood pressure is both common and manageable. But common is exactly the word to sit with, because it is not the same as harmless. High blood pressure remains the leading preventable risk factor for heart disease. The American Heart Association, which tracks blood pressure as one of the eight measures in its Life's Essential 8 framework for cardiovascular health, puts the share of U.S. adults affected at close to 47 percent. That is slightly different from the CDC's 48 percent above because the two figures come from different sources, but both point to the same conclusion: roughly half of American adults are living with high blood pressure. Seeing your reading in the context of your age group is meant to inform you, not to lower the bar.
