Ratings surveys for 2010 have now begun in Australia’s largest capital cities. The Nielsen Company will conduct the usual eight surveys this year for Commercial Radio Australia.

Cities will be in survey for 39 weeks of the year with over 50,000 respondents to be surveyed nationally.

Survey diaries are out in the field for about 5 weeks each survey, with the results being announced about a week after the surveys finish. With Nielsen’s ‘rolling survey methodology,’ two surveys are often rolled together to give a greater sample size and less volatile results.

The first survey books went into the field on 17th January, with Survey 1 results scheduled for release on Thursday Feb 25th.
