Average life expectancy in ancient Rome: Living and dying in the Roman Empire (2024)

Determining the average life span of an Ancient Roman is a difficult task. One of the most difficult problems in this process is that fact that there were a range of different peoples, ages, cultures, and living arrangements, all spread over a thousand years.

Attempting to find the 'average person' in this mix of variables can be tricky. However, there are some elements that historians can use to reach some conclusions.

At the empire's zenith, estimates suggest that the city of Rome itself boasted a population of around one million people, a figure that was unrivaled in the ancient world until well into the Middle Ages.

This urban heart of an expansive empire was a melting pot of cultures, classes, and occupations, each contributing differently to the demographic landscape.

Outside the city, in the rural expanses where the majority of the population resided, life was dictated by the rhythms of agriculture and the seasons.

Here, families tended to be larger, a necessity for the labor-intensive farming that was the backbone of Roman sustenance and wealth.

The rural populace, while less exposed to the urban spread of disease, faced its own set of challenges, from local skirmishes to the whims of nature, which could drastically alter life expectancy.

The divide between rich and poor, free citizen and slave, was stark, with each stratum of society reflecting its own demographic patterns.

Wealthy Romans often enjoyed longer lives, thanks to better nutrition, living conditions, and access to medical care.

Slaves and the poor, on the other hand, faced harsher realities, with their life expectancies significantly shortened by demanding physical labor, inadequate diets, and generally harsher living conditions.

The quest to understand the life expectancy of Ancient Romans is a detective story where the clues are scattered across millennia and the witnesses long silenced.

Quantifying the average lifespan in Ancient Rome is challenging due to the fragmentary and biased nature of the surviving evidence.

The primary sources of data on Roman life expectancy are varied and each comes with its own set of limitations and interpretive challenges.

Literary sources, such as the writings of Pliny the Elder, provide anecdotal evidence and often reflect the perspective of the elite rather than the common populace.

These accounts, while valuable, must be taken with caution, as they can be colored by the author's social standing, political agenda, or philosophical outlook.

Epigraphic evidence, particularly funerary inscriptions, offers more concrete data.

Tombstones frequently included the age at death of the individual, providing a direct insight into life spans.

However, this method is inherently biased toward those who could afford such memorials, typically the wealthier and more prominent citizens.

The epitaphs of the poor, women, and slaves are vastly underrepresented in this archaeological record.

Archaeological findings, including skeletal remains, offer perhaps the most unbiased look at Roman life expectancy.

Through the study of bones, researchers can assess signs of disease, nutritional deficiencies, and physical stress.

Yet, the challenge here lies in the representativeness of the sample. Not all remains have been preserved, and those that have been discovered may not provide a full picture of the diverse Roman population.

Based upon all of this data, historians and archaeologists have pieced together a general picture using the available data from tomb inscriptions, Roman censuses, and skeletal evidence.

The average life expectancy at birth in Ancient Rome was quite low by modern standards, largely due to high infant mortality rates. Estimates suggest that it was between 20 to 30 years.

As a result, the fragility of young life was a specter that haunted every parent, from the plebeian to the patrician.

The perilous journey began at birth, an event fraught with danger for both mother and child.

Without the benefits of modern medical knowledge and hygiene, the chances of surviving the birthing room were far from guaranteed.

For those infants who drew their first breath, the initial years of life were filled with hazards, from malnutrition to the prevalence of infectious diseases.

The lack of effective medical treatments meant that common childhood illnesses could easily prove fatal.

The Roman household gods, the Lares and Penates, were often implored for the protection of these young lives, highlighting the intermingling of hope, religion, and the stark reality of early mortality.

The high infant mortality rate had a profound impact on the average life expectancy figures, skewing them to suggest a much shorter lifespan for the average Roman than for those who survived past childhood.

It's estimated that as many as 25-30% of infants may not have survived their first year of life, and perhaps half of all children would die before reaching adulthood.

In the face of such high rates of child mortality, the Roman state and society developed certain resilience and practicality.

Families tended to be large, both as a result of the value placed on offspring and as a natural response to the expectation that not all children would survive to adulthood.

This demographic strategy was not unique to Rome but was a common feature of pre-modern societies facing similar challenges.

However, if a person survived childhood, their life expectancy would increase significantly.

For example, a Roman reaching the age of 10 could expect to live to around 45 or 50.

Malaria, tuberculosis, and gastrointestinal infections were rampant, exacerbated by the dense urban living conditions and the often inadequate understanding of disease transmission.

The Roman lifestyle, with its public baths and latrines, although advanced in terms of engineering, inadvertently facilitated the spread of pathogens.

The aqueducts, while a marvel that provided fresh water to the city's inhabitants, also had the potential to spread waterborne diseases if not properly maintained.

Nutrition in Ancient Rome varied greatly between the classes. The diet of the average Roman was predominantly cereal-based, supplemented with vegetables, legumes, and occasionally meat, which provided a reasonable nutritional balance.

However, the quality and variety of food available to the poor were far less than that of the wealthy, who could afford a diverse selection of fruits, meats, and exotic spices.

This disparity in diet quality could lead to malnutrition among the lower classes, making them more susceptible to disease and reducing their life expectancy.

Epidemics were another grim reality, with several recorded outbreaks, such as the Antonine Plague and the Cyprian Plague, which swept through the empire with devastating effects.

These outbreaks could decimate populations, disrupt military and economic activities, and create a general sense of fear and helplessness that undermined the social fabric.

While the glory of conquest and the spoils of war were alluring, the reality of military service was often a harsh and perilous existence.

The constant threat of violence was a given, but the soldier's life was also imperiled by the long marches, heavy loads, and the exposure to the elements, all of which took a significant toll on the body.

Campaigns led soldiers far from home, into foreign lands where they faced not only the enemy's sword but also unfamiliar diseases to which they had no immunity.

The crowded conditions of military camps were ideal for the spread of infectious diseases, which could rapidly deplete the ranks.

Dysentery, known colloquially as the 'bloody flux', was particularly feared for its deadly efficiency and the speed with which it could weaken an army.

While specific statistics on soldier mortality are scarce, it's known that military campaigns could be deadly due to battle casualties, accidents, and disease outbreaks.

The Roman military also had a system of medical care for its soldiers, which was notably advanced for its time.

Military doctors, or medici, were assigned to legions and had specialized knowledge in treating battlefield injuries.

However, the effectiveness of such medical care was limited by the state of medical knowledge and the challenges of treating wounds without modern antibiotics.

Wealthier Romans had access to better nutrition, living conditions, and medical care, which likely contributed to a longer lifespan.

It's not uncommon to find records of elite individuals living into their 60s or 70s, and occasionally even beyond.

In contrast, the poor, who made up the majority of the population, faced harsher living conditions and had a lower life expectancy.

Housing for the common people, often in the form of insulae, or apartment blocks, was cramped and frequently lacked basic amenities such as running water and sanitation facilities.

These multi-story buildings were constructed quickly and cheaply, making them prone to collapse and fire.

The close quarters and shared spaces meant that diseases could spread rapidly, and the lack of effective waste disposal contaminated the streets and the Tiber River, which was a source of water for many.

The disparity between the rich and the poor was nowhere more evident than in their living conditions.

The wealthy lived in expansive, well-built domus residences, complete with courtyards, frescoes, and private water supplies.

In contrast, the poor were relegated to the aforementioned insulae, where privacy was scarce and safety concerns were a part of daily life.

The concentration of people and activities in urban centers also meant that when epidemics struck, they did so with lethal efficiency.

The close interaction of people and animals in markets and on the streets facilitated the jump of diseases from animals to humans.

Food supply was another concern; while the city's markets were well-stocked compared to those in the countryside, the reliance on imported grain made the urban population vulnerable to shortages and the inflation of food prices.

Family life was governed by the paterfamilias, the male head of the household, who wielded considerable authority over all members of the family, including extended relatives and slaves.

The emphasis on family was not just a cultural norm but a civic duty, as the Roman state relied on its citizens to produce the next generation of soldiers, workers, and mothers.

Reproduction, therefore, was a matter of state interest as much as personal legacy.

Marriage was encouraged and, in some periods, even incentivized by the state to ensure a steady population growth.

The importance of producing offspring was underscored by the legal and social penalties that could be imposed on those who remained childless.

However, the desire for children was not merely a response to societal pressure; it was also driven by the need for heirs to inherit and continue the family name and estate.

Childbearing was a central expectation of Roman women, and fertility was highly valued.

However, the risks associated with pregnancy and childbirth were significant. Without the understanding of modern obstetrics and the absence of effective pain relief or surgical interventions, maternal mortality was a common and much-feared outcome.

Maternal mortality rates were high due to the lack of hygienic birthing practices and effective medical interventions.

Some estimates suggest that approximately 1 in 50 births resulted in the mother's death, though this figure could vary widely depending on social conditions and the availability of midwifery services.

For those women who survived childbirth, repeated pregnancies could lead to a decline in health, leaving them vulnerable to a range of complications.

Living to the age of 100 in Ancient Rome was an exceptional rarity, but not entirely outside the realm of possibility.

The vast majority of Romans would have considered such a lifespan to be an extraordinary blessing from the gods, a feat akin to Hercules' legendary labors.

While the typical life expectancy was much lower, due to the factors previously discussed, there are records and accounts of individuals who defied the odds and lived to see their centennial year.

These centenarians were noteworthy enough to have their longevity recorded by historians and commemorated by their contemporaries.

For instance, the biographer Pliny the Elder notes instances of individuals living well beyond the norm, and such reports suggest that while reaching the age of 100 was not commonplace, it was celebrated and documented when it did occur.

The few who did reach such an advanced age would have been seen as curiosities, their longevity attributed to a mix of personal habits, genetic predisposition, and the favor of the gods.

They would have been the outliers in a world where many factors conspired to limit the human lifespan.
