Chandigarh and Mohali are two of North India’s most well-planned and rapidly growing cities. Renowned for being sector-planned, these cities are urban development models. But if you are new in the area or just curious, one question that usually comes to mind is: how many sectors in Chandigarh and Mohali?
This piece deconstructs the sectoral composition of the two cities, points out a few interesting facts, and gives a simple explanation that can be understood by everybody.
Understanding the Sector System
Let’s begin by understanding what a “sector” really means in these two cities.
A sector is a planned city area that typically consists of residential areas, markets, parks, schools, and occasionally government buildings. The idea was taken from the master plan of Le Corbusier, the master planner of Chandigarh. Each sector was designed to be self-sufficient and pedestrian-based, which simplified city life and made it convenient.
How Many Sectors Are There in Chandigarh?
Chandigarh is further divided into sectors 1 to 63, but with a twist — all these numbers haven’t been used. Some have been left out or kept aside for a special purpose.
Here’s a breakdown:
- Sectors 1 to 30 are the first planned sectors which were built during the early times.
- Sectors 31 to 47 are the later additions as the city expanded.
- Sectors 48 through 63 are more recent developments, some of which continue to develop in terms of infrastructure.
Sector Numbers That Don’t Exist in Chandigarh:
- Sector 13 does not exist because of the superstitions with the number.
- Sectors 55 to 57 are part of Panchkula administration, not UT Chandigarh.
- Sector 60 and above are still in development or are on the outskirts.
Final Count:
If we exclude overlapping or undeveloped sectors, usable and developed sectors in Chandigarh are approximately 50.
How Many Sectors Are There in Mohali?
Mohali, also known as Sahibzada Ajit Singh Nagar, is a part of Punjab but closely associated with Chandigarh. It was established to alleviate the population pressure on Chandigarh and is now a city in its own right.
In contrast to Chandigarh, Mohali follows a sector numbering system that is a continuation of Chandigarh. Therefore, the sectors in Mohali start from Sector 48 and increase.
Current Sector Numbers in Mohali:
- Sectors 48 to 80 are numbered as part of Mohali.
- Some areas beyond Sector 80 are under development and may not have official sector status yet.
Unique Planning in Mohali:
- Sector planning in Mohali is less formal than Chandigarh’s.
- Commercial hubs like Phase 3B2, Phase 5, and Sector 70 are well-developed and populated.
- Many sectors remain in the planning or construction stage.
Final Count:
As of 2025, Mohali has around 33 to 35 official sectors, though the number is expected to grow as urbanization continues.
