The U.S. population is older now than it has been since record keeping began. The median age in the United States is 38.2 years, up from 36.9 years a decade ago, and from less than 30 in the 1970s.
This trend is the result of several factors – both long and short term. For one, Americans are now living longer than they have in past decades. Driven in part by improvements in health care, average life expectancy at birth in the U.S. is now about 77 years, five years longer than it was in the mid-1970s. More recently, falling birth rates and tightened restrictions on immigration – particularly during the COVID-19 pandemic – have accelerated the aging of the U.S. population.
In some parts of the country, the median age is far higher than the national median. Using data from the U.S. Census Bureau, 24/7 Wall St. identified the 50 U.S. ZIP codes with the oldest populations. Among the places on this list, the median age of the population ranges from about 67 years to well over 80.
Most of the ZIP codes on this list are located in just two states: Arizona and Florida – Sun Belt states where winters tend to be mild, even warm. Favorable climates make many of these communities popular destinations for retirees. Several places, including Laguna Woods in California and The Villages in Florida are specifically designated as retirement communities. Here is a look at what it costs to retire comfortably in every state.
In most of the places on this list, residents appear to be less likely to be starting or raising a family. In all 50 of these ZIP codes, the share of households home to children under the age of 18 is far below the comparable nationwide share of 30.7%. (Here is a look at the best and worst states to raise a family.)

Methodology
To determine the ZIP codes with the highest median ages, 24/7 Wall St. reviewed five-year estimates of median age from the U.S. Census Bureau’s 2020 American Community Survey.
We used ZIP Code Tabulation Areas — a census geography type which defines areal representations of United States Postal Service ZIP codes (USPS ZIP codes do not define geographic boundaries but instead are a network of mail delivery routes in a service area). We refer to census ZCTAs as zip codes.
ZIP codes were excluded if median age was not available in the 2020 ACS or if the sampling error associated with a ZIP code’s data was deemed too high.
The sampling error was defined as too high if the coefficient of variation — a statistical assessment of how reliable an estimate is — for a ZIP code’s median age was above 15% and greater than two standard deviations above the mean CV for all ZIP codes’ median ages. We similarly excluded ZIP codes that had a sampling error too high for their population, using the same definition.
ZIP codes were ranked based on median age. To break ties, we used the share of the population that is 65 and older.
Additional information on the share of the population that is currently enrolled in college, the share of the population that is 18 and younger, the share of the population that is 65 and older, and total population are also five-year estimates from the 2020 ACS.
