In 2022, the state with the highest median age of its population was Maine at 45.1 years. Utah had the lowest median age at 32.1 years. View the distribution of the U.S. population by ethnicity here.

Additional information on the aging population in the United States

High birth rates during the so-called baby boom years that followed World War II followed by lower fertility and morality rates have left the United States with a serious challenge in the 21st Century. However, the issue of an aging population is certainly not an issue unique to the United States. The age distribution of the global population shows that other parts of the world face a similar issue.

Within the United States, the uneven distribution of populations aged 65 years and over among states offers both major challenges and potential solutions. On the one hand, federal action over the issue may be contentious as other states are set to harbor the costs of elderly care in states such as California and Florida. That said, domestic migration from comparably younger states may help to fill gaps in the workforce left by retirees in others.

Nonetheless, aging population issues are set to gain further prominence in the political and economic decisions made by policymakers regardless of the eventual distribution of America’s elderly. Analysis of the financial concerns of Americans by age shows many young people still decades from retirement hold strong concern over their eventual financial position.

In 2021, there were 5,964,526 adults aged 65 and older living in California, the most out of all U.S. states, followed by Florida with almost 4.6 million adults aged 65 and older. Both California and Florida have some of the highest resident population figures in the United States.

In 2021, about 5.96 million people aged 65 years or older were living in California -- the most out of any state. In that same year, Florida, Texas, New York, and Pennsylvania rounded out the top five states with the most people aged 65 and over living there.

The average for 2023 based on 196 countries was 10.17 percent. The highest value was in Monaco: 36.36 percent and the lowest value was in Qatar: 1.57 percent. The indicator is available from 1960 to 2023. Below is a chart for all countries where data are available.

This statistic shows the leading metropolitan areas with the highest percentage of population aged 65 years and over in the United States in 2019. In 2019, The Villages, Florida was ranked first with about 59.5 percent of its population aged 65 years and over.

In 2023, Monaco was the country with the highest percentage of total population that was over the age of 65 with 36 percent. Japan had the second highest with 29 percent, while Portugal and Bulgaria followed in third with 24 percent.

Objective: To examine if the rankings of state HIV age-standardized death rates (ASDRs) changed if different standard population (SP) was used.

Design: A cross-sectional population-based observational study. Setting 36 states in the United States.

Participants: People died from 2015 to 2019.

Main outcome measures: State HIV ASDR using 4 SPs, namely WHO2000, US2000, US2mor020, and Eur2011–2030.

Results: The rankings of 19 states did not change when ASDRs were calculated using US2000 and US2020. Of the 17 states whose rankings changed, the rankings of 9 states calculated using US2000 were higher than those calculated using US2020; in 8 states, the rankings were lower. The states with the greatest changes in rankings between US2000 and US2020 were Kentucky (12th and 9th, respectively) and Massachusetts (8th and 11th, respectively).

Conclusions: State ASDRs calculated using the current official SP (US2000) weigh middle-age HIV death rates more heavily than older-age HIV death rates, resulting in lower ASDRs among states with higher older-age HIV death rates.

The New York Times is releasing a series of data files with cumulative counts of coronavirus cases in the United States, at the state and county level, over time. We are compiling this time series data from state and local governments and health departments in an attempt to provide a complete record of the ongoing outbreak.

Since late January, The Times has tracked cases of coronavirus in real time as they were identified after testing. Because of the widespread shortage of testing, however, the data is necessarily limited in the picture it presents of the outbreak.

We have used this data to power our maps and reporting tracking the outbreak, and it is now being made available to the public in response to requests from researchers, scientists and government officials who would like access to the data to better understand the outbreak.

The data begins with the first reported coronavirus case in Washington State on Jan. 21, 2020. We will publish regular updates to the data in this repository.

As of late 2022, Jeanne Calment was the oldest person who ever lived. Born in Arles, France, in 1875, she died at the age of 122 years and 164 days. The American, Sarah Knauss, followed, having lived 119 years and 97 days. On January 17, 2023, nun Sister André died at the age of 118.

Ageing populations a result of lower fertility rates and higher life expectancies

Population aging indicates a rise in the median age of the population. In 2022, Monaco was the country with the highest percentage of the population aged 65 years and older, amounting to 36 percent. In the same year, Japan recorded the second oldest population globally with 29 percent of the Japanese population over 65. Moreover, Monaco has recorded the highest median age in the world at over 55 years, followed, again, by Japan. In terms of fertility rates, some of the lowest figures can be found across parts of Asia, with Taiwan recording the lowest fertility rate at 1.07 children per woman.

Ageing populations put a strain on the health and social system

Geriatric healthcare refers to the health and care of the elderly. Particularly, this branch of the healthcare system addresses older adults’ healthcare needs and prevents and treats diseases among the older population, such as heart and/or respiratory diseases, cancer, and dementia. For instance, heart diseases and tumors were among the leading death causes in the United States. In most countries, to treat such diseases among others, people need either public or private insurance. In 2022, United Healthcare was the most valuable healthcare service brand worldwide.

In 2023, Italy and Portugal were the European countries with the largest share of elderly population, with 24 percent of the total population aged 65 years and older. Bulgaria, Czechia, and Finland were the countries with the next highest shares of elderly people in their population, while the European Union on average had 21.3 percent of the population being elderly. Iceland, Luxembourg, and Türkiye had the fewest elderly people, with all three having less than 15 percent of their population in this age category.

Monaco is the country with the highest median age in the world. The population has a median age of around 56 years, which is around six years more than in Japan and Saint Pierre and Miquelon – the other countries that make up the top three. Southern European countries make up a large part of the top 20, with Italy, Slovenia, Greece, San Marino, Andorra, and Croatia all making the list. Low infant mortality means higher life expectancy Monaco and Japan also have the lowest infant mortality rates in the world, which contributes to the calculation of a higher life expectancy because fewer people are dying in the first years of life. Indeed, many of the nations with a high median age also feature on the list of countries with the highest average life expectancy, such as San Marino, Japan, Italy, and Lichtenstein. Demographics of islands and small countries Many smaller countries and island nations have populations with a high median age, such as Guernsey and the Isle of Man, which are both island territories within the British Isles. An explanation for this could be that younger people leave to seek work or education opportunities, while others choose to relocate there for retirement.

In 2021, the U.S. states with the highest death rates from Alzheimer’s disease were Mississippi, Alabama, and Vermont. At that time, the death rate due to Alzheimer’s disease in South Dakota was 44 per 100,000 population. However, the state with the highest total number of deaths due to Alzheimer’s disease that year was California, with 16,911 such deaths.

Alzheimer’s disease among the leading causes of death in the U.S. As of 2021, Alzheimer’s disease was the seventh leading cause of death in the United States. The death rate due to Alzheimer’s disease in the U.S. has more than doubled over the past couple of decades, reaching an estimated 37 deaths per 100,000 population in 2019. Age is the biggest risk factor for Alzheimer’s, so it is no surprise that the death rate from the disease increases significantly with age. For example, in 2021, the Alzheimer’s death rate among those aged 85 years and older was 1,244 per 100,000 population, compared to a rate of 214 per 100,000 population among those aged 75 to 84 years.

How many people in the U.S. have Alzheimer’s disease? It was estimated that in 2020, around 6.1 million people aged 65 years and older in the United States were living with Alzheimer’s disease. This figure is expected to increase to around 8.5 million by the year 2030. A rise in life expectancy and the increasing elderly population go some ways in explaining the increase in Alzheimer's in the United States. However, a growing number of Americans are also living with known modifiable Alzheimer’s risk factors such as high blood pressure, obesity, and diabetes.

In 2050, the three East Asian countries Hong Kong (SAR of China), South Korea, and Japan are forecasted to have the highest share of people aged 65 years or more. Except for Kuwait, all the countries on the list are either in Europe or East Asia. By 2050, 22 percent of the world's population is expected to be above 60 years.

Globally, about 25 percent of the population is under 15 years of age and 10 percent is over 65 years of age. Africa has the youngest population worldwide. In Sub-Saharan Africa, more than 40 percent of the population is below 15 years, and only three percent are above 65, indicating the low life expectancy in several of the countries. In Europe, on the other hand, a higher share of the population is above 65 years than the population under 15 years. Fertility rates The high share of children and youth in Africa is connected to the high fertility rates on the continent. For instance, South Sudan and Niger have the highest population growth rates globally. However, about 50 percent of the world’s population live in countries with low fertility, where women have less than 2.1 children. Some countries in Europe, like Latvia and Lithuania, have experienced a population decline of one percent, and in the Cook Islands, it is even above two percent. In Europe, the majority of the population was previously working-aged adults with few dependents, but this trend is expected to reverse soon, and it is predicted that by 2050, the older population will outnumber the young in many developed countries. Growing global population As of 2025, there are 8.1 billion people living on the planet, and this is expected to reach more than nine billion before 2040. Moreover, the global population is expected to reach 10 billions around 2060, before slowing and then even falling slightly by 2100. As the population growth rates indicate, a significant share of the population increase will happen in Africa.

Millennials were the largest generation group in the U.S. in 2023, with an estimated population of 72.7 million. Born between 1981 and 1996, Millennials recently surpassed Baby Boomers as the biggest group, and they will continue to be a major part of the population for many years. The rise of Generation Alpha Generation Alpha is the most recent to have been named, and many group members will not be able to remember a time before smartphones and social media. However, the group already makes up around 42.75 percent of the U.S. population, and they are said to be the most racially and ethnically diverse of all the generation groups, with the oldest Generation Alpha members aging into adolescents this year. Boomers vs. Millennials The number of Baby Boomers, whose generation was defined by the boom in births following the Second World War, has fallen by around seven million since 2010. However, they remain the second-largest generation group, and aging Boomers are contributing to steady increases in the median age of the population. Meanwhile, the Millennial generation continues to grow, and one reason for this is the increasing number of young immigrants arriving in the United States.

According to a population projection based on 2020 Census Data, in 2040, California's population will amount to 42.16 million inhabitants

In 2022, the U.S. states with the highest share of the population that had a disability were West Virginia, Mississippi, and Kentucky. At that time, around 19.5 percent of the population of West Virginia had some form of disability. The states with the lowest rates of disability were Utah, New Jersey, and Colorado.

Disability in the United States A disability is any condition, either physical or mental, that impairs one’s ability to do certain activities. Some examples of disabilities are those that affect one’s vision, hearing, movement, or learning. It is estimated that around 14 percent of the population in the United States suffers from some form of disability. The prevalence of disability increases with age, with 46 percent of those aged 75 years and older with a disability, compared to just 5.8 percent of those aged 5 to 15 years.

Vision impairment One common form of disability comes from vision impairment. In 2022, around four percent of the population of West Virginia had a vision disability, meaning they were blind or had serious difficulty seeing even when wearing glasses. The leading causes of visual disability are age-related and include diseases such as cataracts, glaucoma, and age-related macular degeneration. This is clear when viewing the prevalence of vision disability by age. It is estimated that 8.7 percent of those aged 75 years and older in the United States have a vision disability, compared to 4.3 percent of those aged 65 to 74 and only 0.9 percent of those aged 5 to 15 years.

In 2022, India overtook China as the world's most populous country and now has almost 1.46 billion people. China now has the second-largest population in the world, still with just over 1.4 billion inhabitants, however, its population went into decline in 2023. Global population As of 2025, the world's population stands at almost 8.2 billion people and is expected to reach around 10.3 billion people in the 2080s, when it will then go into decline. Due to improved healthcare, sanitation, and general living conditions, the global population continues to increase; mortality rates (particularly among infants and children) are decreasing and the median age of the world population has steadily increased for decades. As for the average life expectancy in industrial and developing countries, the gap has narrowed significantly since the mid-20th century. Asia is the most populous continent on Earth; 11 of the 20 largest countries are located there. It leads the ranking of the global population by continent by far, reporting four times as many inhabitants as Africa. The Demographic Transition The population explosion over the past two centuries is part of a phenomenon known as the demographic transition. Simply put, this transition results from a drastic reduction in mortality, which then leads to a reduction in fertility, and increase in life expectancy; this interim period where death rates are low and birth rates are high is where this population explosion occurs, and population growth can remain high as the population ages. In today's most-developed countries, the transition generally began with industrialization in the 1800s, and growth has now stabilized as birth and mortality rates have re-balanced. Across less-developed countries, the stage of this transition varies; for example, China is at a later stage than India, which accounts for the change in which country is more populous - understanding the demographic transition can help understand the reason why China's population is now going into decline. The least-developed region is Sub-Saharan Africa, where fertility rates remain close to pre-industrial levels in some countries. As these countries transition, they will undergo significant rates of population growth

As of March 10, 2023, the state with the highest rate of COVID-19 cases was Rhode Island followed by Alaska. Around 103.9 million cases have been reported across the United States, with the states of California, Texas, and Florida reporting the highest numbers of infections.

From an epidemic to a pandemic The World Health Organization declared the COVID-19 outbreak as a pandemic on March 11, 2020. The term pandemic refers to multiple outbreaks of an infectious illness threatening multiple parts of the world at the same time; when the transmission is this widespread, it can no longer be traced back to the country where it originated. The number of COVID-19 cases worldwide is roughly 683 million, and it has affected almost every country in the world.

The symptoms and those who are most at risk Most people who contract the virus will suffer only mild symptoms, such as a cough, a cold, or a high temperature. However, in more severe cases, the infection can cause breathing difficulties and even pneumonia. Those at higher risk include older persons and people with pre-existing medical conditions, including diabetes, heart disease, and lung disease. Those aged 85 years and older have accounted for around 27 percent of all COVID deaths in the United States, although this age group makes up just two percent of the total population
