Kajang, a city nestled in the Hulu Langat District of Selangor, Malaysia, lies approximately 22 kilometers southeast of Kuala Lumpur. It is widely recognized as "Satay Town" due to its culinary fame for satay, a popular local dish. The city's history dates back to settlements by Temuan tribes as early as the 16th century, with its modern form emerging in the 1870s, largely influenced by tin mining and rubber plantations [10, 11]. Kajang was officially granted municipal status on January 1, 1997, evolving from the Hulu Langat District Council [1].

Over the years, Kajang has transformed into a dynamic local authority area, experiencing significant population growth and urban development [9]. Its strategic location, bordered by Kuala Lumpur and Putrajaya, enhances its economic potential and connectivity [9]. The city is also a hub for higher education, hosting numerous institutions that contribute to its vibrant academic and social landscape [1]. This blend of historical roots, economic activity, and educational infrastructure makes Kajang a unique and evolving urban center in Selangor.

Kajang, along with much of the Hulu Langat District, falls under the governance of the Kajang Municipal Council (Majlis Perbandaran Kajang, MPKj) [1]. This municipal council was formally established on January 1, 1997, succeeding the Hulu Langat District Council, which had been in operation since 1986 under the Local Government Act 1976 [9]. The administrative jurisdiction of MPKj encompasses Mukim Kajang, Mukim Cheras, Mukim Semenyih, Mukim Beranang, and Mukim Hulu Langat [9].

The Kajang Municipal Council operates with a vision to be a "livable city driving the nation's economy" and a mission focused on balanced development, livability, and sustainable living to foster local economic generation and a prosperous city [9]. It maintains strong relations with both central and state governments, aligning its policies with national frameworks set by the Ministry of Housing and Local Government [9]. The council aims to provide efficient, quality, and responsible municipal management services, emphasizing transparency and customer satisfaction [9].

Kajang's economy has historically been shaped by primary industries such as tin mining and rubber plantations, particularly flourishing in the late 19th century [11]. While direct, up-to-date economic statistics specific solely to Kajang are not readily available, its integration into the larger Selangor state and proximity to Kuala Lumpur, Malaysia's economic capital, signifies a diverse and growing economic landscape [1, 9]. The city serves as a significant residential area, supporting various local businesses and services.

Modern economic activities in Kajang are evident through its multiple shopping complexes like De Centrum Mall, Plaza Metro Kajang, and Metro Point Complex, indicating a vibrant retail sector [6]. The presence of numerous higher education institutions also contributes to the local economy through employment, student spending, and research activities [1]. The Kajang Municipal Council actively promotes a balanced and sustainable development to drive the local economy, aiming for a prosperous urban environment [9].

Kajang boasts a well-developed infrastructure that supports its growing population and economic activities. The city is highly accessible via an extensive network of expressways and federal highways, including Federal Route 1, the Grand Saga Expressway, the SILK Expressway, and links to the PLUS Expressway [1]. These roads form a crucial transport artery, connecting Kajang to Kuala Lumpur and other key towns in Selangor and Negeri Sembilan [1].

Public transport is also a significant component of Kajang's infrastructure, with the Kajang railway station serving as a major interchange for the MRT Kajang Line, KTM Seremban Line, and KTM ETS [1]. While Kajang station is a principal rail hub, the Stadium Kajang MRT station is more centrally located for downtown access [1]. In terms of public services, Kajang Hospital serves as the primary public medical facility, complemented by several private medical centers [1]. The Hulu Langat District Police Headquarters are situated in the town center, along with branches of other federal government agencies such as the National Registration Department and Immigration Department [1].
