Formed in 2020 through the merger of the former Asker, Røyken, and Hurum municipalities, it ranks as Norway's eighth-largest municipality by population and serves as a prosperous commuter suburb to the capital. Often referred to as a peninsula just outside Oslo, Asker is renowned for its affluent residential areas, high-end shopping, cultural institutions, and natural beauty, including fjords, lakes, and forests. The municipality's coat of arms features a blue wave on a silver background, symbolizing its coastal heritage. As one of Norway's wealthiest regions, Asker emphasizes sustainability and circular economy initiatives, positioning itself as a model for urban-rural integration. In 2025, with ongoing development in green technologies and community events, Asker continues to attract residents and visitors seeking a blend of urban convenience and outdoor lifestyles.
Asker spans 364.4 square kilometers, encompassing a diverse landscape of coastal fjords, rolling hills, forests, and agricultural lands. Situated on a peninsula along the inner Oslofjord, it borders Bærum to the northeast, Lier to the northwest, and Drammen to the west, with marine boundaries on the Oslofjord to the east and south. Key geographical features include the Semsvannet Lake, a popular recreational area, and marinas like Vollen, which provide access to boating and waterfront activities. The terrain varies from sea-level fjord shores to inland elevations up to 500 meters, supporting biodiversity in wetlands and woodlands. Asker's proximity to Oslo (about 30 minutes by train) makes it an ideal commuter hub, with major transport links including the E18 highway and the Asker Line railway. This location fosters a temperate climate moderated by the fjord, while offering scenic views of the surrounding Scandinavian landscape.
Asker's history dates back to prehistoric settlements, with evidence of Stone Age and Viking-era activity along the fjord. The area developed as agricultural and fishing communities in the Middle Ages, with Asker proper gaining prominence in the 19th century as a rural district. The original Asker municipality was established in 1838 under Norway's formannskapsdistrikt law. Industrialization in the late 1800s brought railways and growth, transforming it into a desirable suburb for Oslo's elite. During World War II, Asker served as a resistance hub, with local forests hiding partisans. Post-war, rapid urbanization occurred due to Oslo's expansion, leading to affluent residential developments. The pivotal 2020 merger with Røyken and Hurum created the modern municipality, enhancing administrative efficiency and regional cooperation. In recent years, Asker has focused on sustainable projects, including circular economy pilots, reflecting Norway's environmental priorities. By 2025, this evolution underscores Asker's role as a modern, integrated community preserving its historical charm.
In 2025, Asker Municipality has an estimated population of 100,492, marking a 1.3% annual growth rate from 2020.

The population is diverse, with a balanced gender ratio (about 50.1% male) and an average household size typical of suburban Norway. Residents, known as Askerfolk, include a mix of professionals commuting to Oslo, families, and retirees, drawn by high living standards.

Demographic trends reflect national patterns, with an aging population offset by influxes from urban expansion and family-friendly policies.
Asker's economy thrives on its proximity to Oslo, with many residents employed in finance, technology, and services in the capital. Locally, sectors include retail, with high-end shopping districts, and emerging green industries under circular economy frameworks. Agriculture persists in rural areas, while tourism boosts revenue through fjord activities and cultural sites. Major employers encompass public services, education, and small businesses in manufacturing and IT. As one of Norway's wealthiest municipalities, Asker benefits from high property values and low unemployment. In 2025, amid Norway's projected mainland GDP growth of 1.5-2.3%, Asker focuses on sustainable initiatives, such as waste reduction and renewable energy, aligning with national oil revenue investments in green transitions. Challenges include housing affordability, addressed through development projects.
