There are two types of regions – formal and functional regions.
1. A formal region is also known as uniform region or homogeneous region. It is an area in which everyone shares in common one or more distinctive characteristics. It can be common physical characteristic such as relief or climate of the region. It can be socio-cultural or economic activity such as common language. For example, rice producing regions.
2. In some formal regions, there are boundaries. Thus, district, state or country may be formal region. For example, USA and Canada are the examples of formal regions.
3. In functional regions characteristics are not important but functions are more important.
4. In one functional region, there may be many political or physical regions but due to one common function it is said to be functional. For example, Mumbai metropolitan or Pune metropolitan regions.
