IBR 2007 - Survey methodology

Size Of Businesses Surveyed

IBR is conducted among medium-large privately held businesses. Definitions of the size of a medium and large business are determined by local government classifications as shown in the table below.

Survey Respondents

IBR surveys the opinions and expectations of chief executive officers, managing directors, chairmen or other senior executives from over 7,800 privately held businesses across 34 economies (title dependent on what is most appropriate for the individual country).

Interview Technique

The research is carried out primarily by telephone interview lasting approximately 15-20 minutes with the exception of Japan (postal), Philippines and Armenia (face to face), mainland China and India (mixture of face-to-face and telephone) where cultural differences dictated a different approach. Telephone interviews enable Grant Thornton International to conduct the exact number of recommended interviews and to be certain that the most appropriate individuals are interviewed in an organisation which meets the profile criteria.

Data collection is managed by Grant Thornton International's core research partner -Experian Business Strategies. Questionnaires are translated into local languages with each participating country asking a small number of country specific questions as well as the core questionnaire.

Participating Countries

In 2008 the IBR survey was conducted in 34 economies and now covers over 7,800 respondents following the addition of Belgium, Denmark and Vietnam. The table below shows the countries that participated in the survey along with the number of respondents interviewed and the definition of "medium to large sized" businesses used to screen the respondents.

Balance Statistic

A balance statistic reports the percentage of respondents who reported a figure rising less the percentage who reported it falling. It not only provides a useful summary statistic, but numerous studies have shown it is well correlated with economic time series data and that it performs as well as highly complex methods of analysing survey data to predicting economic outcomes.

Sample Validity

In deciding upon the number of respondents to interview in each country, consideration was given not only to the size of the country but also to the statistical reliability of the data. In line with this we have placed a minimum of 100 interviews in each country as this is the accepted minimum for statistical reliability. In order to increase the reliability of the data we have exceeded this minimum in the majority of countries. Indeed in some of the larger economies we have interviewed 500 or more. This also allows us to look at various sub-sets such as industry type and regional comparisons.
