Regions of Greece – Decentralized Administrations

Greece is divided into 13 administrative regions. The administrative regions of Greece are the thirteen first-level administrative units of the country that play an important role in decentralizing governance and promoting regional development.

These regions were established in 1986 to provide a modern structure for the country’s administration. This restructuring was based on earlier divisions, but adapted to the country’s evolving needs. The creation of these regions was a strategic move to strengthen local governance and promote balanced regional development.

Greece covers an area of 50,949 square miles and is home to approximately 10.4 million people. The administrative regions of Greece serve as the backbone of the country’s administrative structure. These regions not only facilitate effective governance, but also contribute to the country’s economic development and cultural identity.

For example, Attica/Athens, the capital region, is the political, economic and cultural center of the country. On the other hand, regions such as the Aegean Islands and Crete are renowned for their natural beauty, attracting tourists from all over the world. These regions, with their unique characteristics and offerings, form the diverse tapestry of Greece, contributing to its rich cultural heritage and robust economy.

Regional Governance

Each region in Greece is governed by a popularly elected regional governor and a regional council, both of whom serve five-year terms. This democratic system of regional government was introduced to replace the prefectures and decentralize power. Many of the powers of the prefectures were transferred to the regional level, allowing for more efficient administration and better representation of regional interests.

For example, the regional governor of Attica/Athens is responsible for addressing the specific needs of this densely populated urban region, while the regional governor of the Aegean Islands would focus on promoting tourism and preserving the natural environment. In this way, the regional governance system allows for tailored strategies and policies to meet the specific needs and characteristics of each region.

Administrative Regions and their Populations

  • Attica is the most populous administrative region in Greece, which includes the Athens metropolitan area and is home to approximately 3,750,000 people.
  • Central Macedonia follows as the second most populous region with a population of about 1,874,590 people.
  • Thessaly is the third most populous region, with about 730,730 inhabitants.

The distribution of population across these administrative regions has implications for various sectors, including infrastructure, healthcare and education.

For example, the high population density in Attica requires robust urban infrastructure and extensive public services. Conversely, regions with lower population densities, such as the Aegean islands, may require a different approach focused on sustainable tourism and environmental protection. Understanding the distribution of population across Greece’s administrative regions is therefore key to effective planning and policy-making.

Size of the Administrative Regions

In terms of geographical size, Central Macedonia leads as the largest region in Greece, covering an area of about 7,262 square miles. Central Greece follows as the second largest region with an area of about 6,003.62 square miles. The different sizes of the administrative regions have a significant impact on the distribution of resources and the development of infrastructure.

For example, larger regions such as Central Macedonia may require more extensive transportation networks to facilitate connectivity within the region. On the other hand, smaller regions may focus more on the development of specific sectors, such as tourism in the Aegean islands. Thus, the size of administrative regions influences strategic planning and development initiatives in Greece.

Decentralized Administrations of Greece

In addition to the administrative regions, Greece also has seven decentralized administrations (link). These decentralized administrations group regions under a government-appointed Secretary General. They are designed to ensure the effective implementation of state policies at the regional level and serve as a bridge between the central government and the regional authorities.

This system of decentralized administrations facilitates greater coordination and cooperation between different levels of government. For example, during a national crisis, the secretary general of a decentralized administration can work closely with regional governors to ensure a unified and effective response. This system therefore plays a crucial role in the smooth functioning of public administration in Greece.
