The US, the UK and France remained the leading source countries for inbound travel to India in 2012, as large student and working expatriate populations reside in these countries. Also, the concept of gaining a visa on arrival to India for tourists coming from Singapore and other countries such as Finland, Vietnam and Indonesia among others helped to increase inbound tourism during the year.
Arrivals are expected to rise at a CAGR of 10% over the forecast period. This growth is primarily expected to be driven by arrivals from countries such as Brazil, Nepal, Malaysia and Egypt. These cities in 2012 had small number of arrivals in the country, and hence are expected to witness a stronger growth as compared to the matured markets such as the UK and the USA.
