We currently undertake the research (now in its 11th year in New Zealand), in 31 countries across Europe, Asia-Pacific and the Americas. To ensure the research is objective, we select the 150 largest companies in each of those chosen countries. The selection criteria is companies with more than 1,000 employees. This list is presented to a representative cross section of relevant respondents based on region, age and gender between the ages of 18-64. There is a slight emphasis towards respondents under 40 as the survey's main target audience are potential employees. In New Zealand, the number of respondents is 4,276.
