The history of the Roman economy covers the period of the Roman Republic and the Roman Empire. Recent research has led to a positive reevaluation of the size and sophistication of the Roman economy.

Gross domestic product [edit]

All cited economic historians stress the point that, given the general paucity of relevant data from antiquity, any estimate can only be regarded as a rough approximation to the realities of the ancient economy.

Total GDP c. 1 AD for different regions.[11]

Italia is considered to have been the richest region, due to tax transfers from the provinces and to the concentration of elite income in the heartland; its GDP per capita is estimated at having been around 40%[10] to 66%[12] higher than in the rest of the empire.


Demography [edit]

In recent years, questions relating to ancient demographics have received increasingly more scholarly attention,[13] with estimates of the population size of the Roman empire at its demographic peak now varying between 60–70 million ("low count") and over 100 million ("high count").[14] When adhering to a more traditional value of ca. 55 million inhabitants, the Roman Empire still constituted the most populous Western political entity until the mid-19th century and likely remained unsurpassed worldwide until the 2nd millennium AD.[15]

Industry [edit]

Mining and metallurgy [edit]

World production of lead, estimated from Greenland ice cores, peaked in the 1st century CE, and strongly declined thereafter.[16] World production would only surpass Roman levels in the middle of the 18th century.

The invention and widespread application of hydraulic mining, namely hushing and ground-sluicing, aided by the ability of the Romans to plan and execute mining operations on a large scale, allowed various base and precious metals to be extracted on a proto-industrial scale only rarely, if ever, matched until the Industrial Revolution.[17]

Annual metal production in metric tons
Output per annum Comment
Iron 82,500 t[18] Based on "conservative estimate" of iron production at 1.5 kg per head, assuming a population size of 55m[19]
Copper 15,000 t[20] Largest preindustrial producer[21]
Lead 80,000 t[22] Largest preindustrial producer[23]
Silver 11,200 t[24] At its peak around the mid-2nd century AD, Roman stock is estimated at 10,000 t, five to ten times larger than the combined silver mass of medieval Europe and the Caliphate around 800 AD.[25]
Gold 11,119 t[26] Production in Asturia, Callaecia, and Lusitania (all Iberian Peninsula) alone


The most common fuel by far for smelting and forging operations, as well as heating purposes, was wood and particularly charcoal, which is nearly twice as efficient.[27] In addition, coal was mined in some regions to a fairly large extent: Almost all major coalfields in Roman Britain were exploited by the late 2nd century AD, and a lively trade along the English North Sea coast developed, which extended to the continental Rhineland, where bituminous coal was already used for the smelting of iron ore.[28]

Agriculture [edit]

Roman agriculture was self sufficient for most of the Roman population.[29] The Romans improved crop growing by watering growing plants using aqueducts and there is an increasing amount of evidence that some parts of the industry were mechanised. For example, extensive sets of mills existed in Gaul and Rome at an early date to grind wheat into flour. The most impressive extant remains occur at Barbegal in southern France, near Arles. Sixteen overshot water wheels arranged in two columns were fed by the main aqueduct to Arles, the outflow from one being the supply to the next one down in the series.

Trade [edit]

Number of Mediterranean shipwrecks, 8 BC – 15 CE[30]

According to archaeological evidence there was a large increase in the volume of long distance trade during Hellenistic and early Roman Imperial times followed by a large decrease. This is evidenced in the archaeological data on the number of shipwrecks found in the Mediterranean Sea.

Industrial output [edit]

The majority of the people of the Roman Empire lived in destitution, while the small fraction of the population that engaged in commerce was much poorer than the elite. Industrial output was minor, due to the fact that the majority poor could not pay for the products. Technological advance was severely hampered by this fact. Urbanization in the western part of the empire was also restricted by low overall population density and the poverty of the region. Low labour costs brought about by slavery may also have contributed to the lack of development in mechanical means of production.[31]

"the empire's commercial classes remained small and enjoyed neither wealth nor the status of the landowning aristocracy...most production in the empire was small scale and under-capitalized, the rich preferring to invest in land. It is in any case doubtful, in view of the poverty of most of the empire's population, whether the markets existed to support a greater degree of industrial production. This is probably on of the factors behind the surprising lack of technological innovation in the empire...The ready availability of cheap slave labor may also have deterred investment in expensive machinery....But most of the west was too poor and underpopulated to support this level of urbanization and towns remained primarily administrative or military centers."
