Why Urbanisation Vocabulary Matters for IELTS
Urbanisation questions appear in Writing Task 2 (e.g. “What problems does urbanisation cause and how can they be solved?”) and are also common in Task 1 Academic (describing population growth charts). Speaking Part 3 may ask about city vs rural life. The topic connects to environment, transport, government, and society, making it highly versatile.
