The Vellore Municipal Corporation oversees six key departments: General Administration/Personnel, Engineering, Revenue, Public Health, Planning, and Information Technology (IT), all managed under the executive control of a municipal commissioner. Legislative authority resides with a 60-member body of elected councilors, led by an elected mayor and a deputy mayor.

Vellore is represented in the Tamil Nadu Legislative Assembly through the Vellore, Katpadi, and Anaicut constituencies, and in the Lok Sabha through the Vellore and Arakkonam constituencies [1]. Law enforcement is managed by the Vellore subdivision of the Tamil Nadu Police, which includes four police stations, one dedicated to women, alongside specialized task forces [1].

Vellore's economy is notably driven by its strong tertiary sector, which accounts for approximately 83.35% of the workforce in transport, services, and commerce, while manufacturing and household industries employ 13.52%. The city is widely recognized as India's "leather hub," with numerous leather and tannery facilities in and around Vellore, Ranipet, Ambur, and Vaniyambadi, contributing over 37% to India's total leather and leather-related product exports. Major industrial presences include Bharat Heavy Electricals Limited (BHEL) and Tamil Nadu Industrial Explosives Limited (TEL), Asia's largest explosives manufacturing company. International brands like EID Parry, Mitsubishi, and MRF also have manufacturing units in the region.

The Christian Medical College & Hospital (CMCH) is Vellore's largest private employer, significantly boosting the local economy through medical tourism and allied businesses. Rural industries such as weaving, beedi making, and matchstick rolling also contribute to the local income, with military spending from numerous recruits in the Indian Armed Forces providing another substantial economic source [1].

Vellore's business environment is characterized by its significant role in the leather industry, making it a major exporter of finished leather goods in India. The presence of large government-owned enterprises like BHEL and specialized companies such as Tamil Nadu Industrial Explosives Limited highlights the industrial diversity. International manufacturing units, including EID Parry and Kramski Stamping and Molding, underscore the city's appeal to global businesses, particularly in sectors like sanitary-ware, automotive components, and chemicals in the SIPCOT economic zone. The thriving healthcare sector, anchored by Christian Medical College & Hospital, supports a substantial service industry, attracting a large "floating population" and fostering growth in lodging and related businesses.

Additionally, Microsoft Corporation (India) Pvt. Ltd. has established innovation centers in the region, signaling a growing focus on fostering technological expertise. The city's overall economic growth has been marked by a shift from primary to tertiary sector activities, creating diverse employment opportunities across various industries [1].

Vellore benefits from a well-developed transportation network, featuring extensive road and rail connectivity. The municipal corporation maintains over 104 km of roads, and major National Highways (48, 38, 40, 75) pass through or terminate in the city, linking it to major urban centers across Tamil Nadu, Andhra Pradesh, and Karnataka. The city's bus service operates from two main terminals, and a new integrated bus terminus was completed in January 2022.

Utility services include electricity supplied by the Tamil Nadu Electricity Board (TNEB) and water from the Palar River. The municipal corporation manages solid waste collection, though an underground drainage system is absent, relying on septic tanks and open drains. The city also provides healthcare facilities through 24 government and private hospitals and maintains street lighting and a daily market [1].

Vellore is emerging as a significant center for technological advancements and education in India. It is home to the Vellore Institute of Technology (VIT), a highly-ranked private engineering university, and hosts Thiruvalluvar University, which affiliates numerous arts and science colleges in the region. The city established India's first stem-cell translational research center in December 2005 at the Christian Medical College (CMC), a testament to its advanced medical research capabilities. This center has notably achieved breakthroughs, such as reprogramming adult mouse cells to function like human embryonic stem cells. Furthermore, Microsoft Corporation (India) Pvt. Ltd. has launched one of its 14 Microsoft Innovation Centers (MICs) in Vellore, indicating a growing focus on fostering technological expertise.
