Athens operates under a mayor-council government system. The Municipality of Athens is responsible for managing the city’s administration, public services, and infrastructure. The city is divided into seven districts, each having local administrative responsibilities. The Mayor of Athens, currently Haris Doukas, is elected for a four-year term and oversees municipal governance. The mayor is responsible for implementing policies, managing city services, and representing Athens at national and international levels.

The Athens City Council consists of elected representatives who debate and approve policies, budgets, and development plans. The council works closely with the mayor’s office to address urban planning, public transportation, and environmental policies.

Athens is also part of the Attica Region, governed by the Regional Governor, who manages broader regional issues such as transport infrastructure and economic development. The Greek central government, based in Athens, oversees national policies, with the Hellenic Parliament playing a key role in legislative decisions.

Law enforcement is managed by the Hellenic Police, ensuring public safety. Judicial matters are handled by local courts, including the Athens Court of First Instance. Public services such as waste management, utilities, and transportation are provided by municipal and regional agencies.

Athens, the capital city of Greece, serves as the country's primary economic hub, contributing significantly to the national economy. As of 2025, Greece's Gross Domestic Product (GDP) is projected to reach approximately $265.171 billion USD, with Athens accounting for a substantial portion of this figure.

The city's economy is diverse, encompassing sectors such as finance, tourism, shipping, and manufacturing. Athens is home to the Athens Stock Exchange and the headquarters of numerous prominent Greek companies, including Hellenic Petroleum and Alpha Bank. The port of Piraeus, located in Athens, is one of the busiest in Europe, playing a crucial role in both passenger travel and cargo shipping.

Tourism remains a vital component of Athens' economy. In 2018, the city welcomed over 5 million tourists, with 1.4 million visiting for short stays. This influx contributes significantly to local businesses, including hotels, restaurants, and retail establishments.

In recent years, Athens has experienced economic growth, with projections indicating a continuation of this trend. The International Monetary Fund (IMF) projected Greece's economy to grow by 2.1% in 2025, primarily driven by investment. This growth is supported by structural reforms, increased investments, and a robust tourism sector.

Despite these positive developments, challenges persist. The unemployment rate, although declining, remains a concern. Efforts to enhance tax compliance and reduce public debt are ongoing, aiming to strengthen the economic stability of both Athens and Greece as a whole.
