The Middle Ages is a periodization of European history from the 5th century to the 15th century. The Middle Ages follows the fall of the Western Roman Empire in 476 and precedes the Early Modern Era.

, including population trends and movements. Demographic changes helped to shape and define the Middle Ages. Population trends in Europe during the Middle Ages can be roughly categorized:
  • 150–400: population decline
  • 400–1000: stable at a low level.
  • 1000–1250: population boom and expansion.
  • 1250–1350: stable at a high level (with the exception of the Great Famine

Land was plentiful while labour to clear and work the land was scarce; lords who owned the land found new ways to attract and keep labour.

  • A Marxist alternative is that by 1250, the increasing population led to competition for land, and a great imbalance between landowners and workers. Thus rents went up, and wages fell, further redistributing wealth towards rich property owners and away from poor tenant farmers. The economic condition of the poor prevented further population growth and increased mortality from epidemics. Once the population had decreased, wages increased, as did mobility of labour and redistribution of wealth. Landowners tried to resist change through wage freezes and price controls. This struggle was partly responsible for continued popular uprisings
    Popular revolt in late medieval Europe
    Popular revolts in late medieval Europe were uprisings and rebellions by peasants in the countryside, or the bourgeois in towns, against nobles, abbots and kings during the upheavals of the 14th through early 16th centuries, part of a larger "Crisis of the Late Middle Ages"...

     argues that the rise of absolutism weakened competing power centers, notably church and feudal authority. Resulting weakened property rights reduced incentives to maintain the level of capital stock required to support the population. Thus the centralization of power leading to weak property rights is the disease, the symptoms of which are events such as the Black Plague's resulting from decreased expenditure on sanitation infrastructure.


Regardless of the cause, populations continued to fall and remained low into the 16th century.

Science and art of medieval demography

Medieval demography is a fairly new area of study. The sources traditionally used by demographers, such as marriage, birth and death records, are generally not available for this period, so scholars rely on other sources: field data (archaeological) and available written records.

Examples of field data include the physical size of a settlement, and how it grows over time, and the appearance, or disappearance, of settlements

, participants in an oath. However these cannot be relied on as accurate, and are most useful as supporting evidence rather than being taken factually on their own.

The most important written accounts are those contained in administrative records. These accounts are more objective and accurate because the motivation for writing them was not to influence others. These records can be divided into two categories: surveys and serial documents. Surveys cover an estate or region on a particular date, rather like a modern inventory. Manorial surveys were very common throughout the Middle Ages, in particular in France and England, but faded as serfdom gave way to a money economy. Fiscal surveys came with the rise of the money economy, the most famous and earliest being Domesday Book

 in 1086. The Book of Hearths from Italy in 1244 is another example. The largest fiscal survey was of France in 1328. As kings continued to look for new ways to raise money, these fiscal surveys increased in number and scope over time. Surveys have limitations, because they are only a snapshot in time; they do not show long term trends, and they tend to exclude elements of society.

Serial records come in different forms. The earliest are from the 8th century and are land conveyances such as sales, exchanges, donations, and leases. Other types of serial records include death records from religious institutions and baptismal registrations. Other helpful records include heriot
