Recommendations for Measuring International Demographics

a new ESOMAR series

The process of describing and defining populations is currently very varied. Methods differ from one research company to the next, measures go quickly out of data, and research respondents don’t always tell researchers the truth or give a proper answer to some demographic questions, resulting in misrepresentation and poor-quality data.

ESOMAR, through its Professional Standards Committee, is developing a series of recommendations on demographic standards to address inconsistencies that create barriers and inefficiencies in the exchange and evaluation of international data.

The series will cover international best practice recommendations for: 

  • Age validation 

  • Gender

  • Working status measurement 

  • Income measurement 

  • Education level measures by country and inclusive method of assessing education levels 

  • Job and industry definitions 

  • Global wealth range/measures 

  • Social class measurement

Who's working on it?

An expert project team from a range of international suppliers is working together to review best practices to describe demographic questions in as globally consistent a way as possible to develop best practice recommendations for key geographies worldwide. Growing international cross-market research levels will help researchers and clients everywhere to improve research standards. The team is chaired by Judith Passingham, chair of ESOMAR's Professional Standards Committee and Jon Puleston of Kantar, and a member of the Standards Committee.

The recommendations, founded on evidence-based best practices, are designed to improve quality standards and facilitate multi-country research projects and surveys. The proposals will help to produce more meaningful global/regional results that are more comparable from one project/region to another. All recommendations are sent to a Client Sounding Board for review and buy-in.   

Where are we now?

The team is currently finalising how to 'ask the age question' in a way comparable from project to project and is also best practice from a privacy point of view and more considerate of participants. The question should lead to more accurate information, less participant drop-out and less privacy exposure for suppliers and clients. 

For instance, the question about someone’s age can be asked in various ways. Some people might give the wrong answer (they forget how old they are or wish to appear younger), or they do not like being asked a question they have already been asked when signing up for a panel; or if they are older, they don't want to scroll down lots of years to come to their year of birth. Plus, many clients like to use different age bands, depending on the segment they are interested in. All this leads to inconsistencies and issues with the data. Next, we will tackle the gender and working status questions.
