Whilst often cited as one of the fastest growing sectors of tourism , no comparable statistics really exist to determine the exact size of the voluntourism market. This is partly due to differences of definition in what constitutes voluntourism, versus volunteerism or tourism, and partly due to immeasurability of its activity .
Various (incomparable) market statistics include:
- In 2004, there were more than 800 organisations providing overseas volunteering in 200 countries. 
- In 2006, voluntourism was estimated to be worth US$150 million.
- In 2008, a Tourism and Research Marketing survey of 300 organisations estimated the market size to be 1.6 million volunteer tourists per year worth £1.3 billion .
- In 2008, the market was estimated to have grown 5-10% in Western Europe over the course of five years .
- In 2009, GeckoGo’s survey of more than two thousand voluntourists worldwide found the UK to be the third largest originating market.
- In 2012, 35% of adults said they would like to try a holiday involving a voluntourism component, in addition to the 6% who had already done so .
- [updated] In 2015 Nancy Gard McGehee(Virginia Tech) estimated 10 million volunteers a year spending up to $2 billion.
- [updated] By the end of the 2010s, it is estimated voluntourism could represent 25 – 30 million worldwide, with the US market alone adding around 1 million additional voluntourists per year since 2007 to reach 10 to 15 million. .
GeckoGo’s 2009 survey also revealed voluntourists’ preferences, although not UK specific include:
- Duration: 44% prefer trips longer than one month, 42% between two weeks and a month.
- Destinations: Peru (23%) and Brazil (14%) topped the polls (though an US respondents skew to shorter distances/cheaper opportunities could be responsible).
- Project types: 62% would like to undertake humanitarian voluntourism, 56% conservation, 56% teaching, 53% community development and 28% construction.
However, without being able to define the scope and extent of the market, it is difficult to determine the best approach for regulation and auditing. Without regulation, negative impacts which may outweigh positive benefits warrant the critical scrutiny of much media coverage, potentially adding greater value to the industry through debating the multi-lateral collaborative stakeholder approach required than any market statistics would ..
