6,800-Year-Old Serbian Village Was Remarkably Equal

A Neolithic village in Serbia just got a serious upgrade, twice the size researchers once thought, and, according to a new statistical measure, unusually fair for its time.

Returning to Opovo Without Digging a Single New Trench

Opovo Ugar-Bajbuk sits in Serbia’s Vojvodina region and belonged to the Vinča culture, a network of Late Neolithic communities across southeastern Europe known for large settlements and long-distance trade. Archaeologists first excavated the site in the 1980s, estimating it covered about 5 hectares and supported roughly 200 people. A German-Serbian team led by Fynn Wilkes of Kiel University’s ROOTS Cluster of Excellence returned between 2022 and 2024, this time relying mostly on non-invasive methods: surface finds, geomagnetic surveys to map buried structures, core samples, and new radiocarbon dating, without large-scale excavation.

A Settlement Twice the Size Once Believed

The new survey nearly doubled Opovo’s known footprint to about 9.4 hectares, with between 180 and 220 individual house structures identified across the site. Population estimates rose accordingly, from the original figure of around 200 to a peak of up to 711 people. Refined radiocarbon dates placed the settlement’s main occupation between roughly 4850 and 4725 BC. The site grew in stages: an early phase covering about 4.3 hectares was enclosed by a ditch around 4850 BC, and the community expanded into a second area around 4820 BC, filling in part of the original ditch while building larger ones around the newly expanded settlement.

Measuring Equality Through House Size

To get a sense of Opovo’s social structure, researchers turned to house size as a rough stand-in for material wealth and calculated a Gini index, the same statistical tool economists use today to measure income inequality, running from 0 for perfect equality to 1 for maximum inequality. Opovo came out at 0.22, a figure close to some of today’s most economically equal countries, such as Slovenia or Norway, and well below the roughly 0.40 typical of the United States. The result sits slightly under the average for other Late Neolithic sites across the wider Carpathian Basin, based on a 2025 study in Science Advances. The researchers caution that house size captures only one form of wealth, and other kinds of status or resources would need separate study to complete the picture.

Cooperation Without Coercion

Opovo’s fortifications offer another clue about how the community organized itself. Researchers identified as many as five enclosing ditches built over the settlement’s history, substantial earthworks that would have required considerable coordinated labor. The study found no evidence of forced labor behind their construction, suggesting the community built these defenses through cooperation rather than compulsion by a powerful elite. Why people eventually abandoned Opovo after around 4725 BC remains unclear, and researchers say environmental, economic, or social factors could all have played a role, though current evidence doesn’t point to one specific cause. Future work will study the sequence in which the ditches were built and compare Opovo to other Late Neolithic settlements across the region.
