SAARF RAMS release 6 for 2012

Objectives:

More specifically, the objectives covered:

• Radio stations listened to during a seven-day period
  
• Times listened to each station, for each day of the week, for each quarter hour of the day from 00h00 to 24h00
  
• Radio stations listened to in the past four weeks
  
• Favourite radio stations

Universe:

As of 2009, SAARF expanded the AMPS/RAMS universe to include 15 year-olds.

The survey covers adults aged 15 years and older, who are living in the nine provinces of South Africa.

Method:

Radio self-completion diaries were placed with respondents to complete in their homes over a seven-day period,
for which they were offered a small incentive.

Respondents were instructed on how to complete the SAARF RAMS Diary.

Sample design:

A probability sample stratified by area was drawn.

The sample was equally apportioned between males and females with the exception of mines, hostels and domestics. At each sampling point a cluster of two addresses was drawn.

In each household, the main respondent was selected by means of a random grid. Four calls were made before substitution could occur.

During the survey period, household "flooding" was implemented. In addition to placing a diary with the main respondent, supplementary diaries were placed and completed by all other members of the household aged 15 years and over.

As of 2009, the flooding methodology was expanded to include the small urban and rural areas.

The main advantage of flooding is to allow for reporting on a more robust sample. A total of
24,893 diaries were collected over the two fieldwork waves.

Fieldwork:

The large urban fieldwork for this sixth release wave of 2012 was conducted in two parts: the first part from end August to mid-October 2012, and the second from mid-October to mid-December 2012. The small urban/rural fieldwork for this release was conducted from mid-January to end June 2012.

The 2009-2013 SAARF RAMS contract was awarded solely to Nielsen. Fieldwork since 2009 has been conducted solely by Nielsen. A 20% back-check was conducted on all interviewers.

Analysis of results:

All findings in the Radio Services report are based on adults 15 years and over.

Reporting is on the combination of the two waves of interviewing. Results were weighted up to total population.

Special Note: Population figures were updated in May 2012, using the population estimates provided by IHS Global Insight. It should be noted that the methodology employed in the IHS demographic model is different to the previous BMR model in a number of technical areas.

Users should also note that when there is a universe update, the figures in thousands that one looks at may not be directly comparable with one another.

Comparisons in thousands with RAMS surveys previous to the May 2012 release should be treated with caution.

Analysis of results was provided in total, and by demographic breakdowns as follows:
- Age
- Community size
- Sex
- Home language
- Household income
- Household purchaser
- Languages understood
- Languages spoken (Other)
- Level of Education
- Living Standards Measure
- Metropolitan area
- Population group
- Province
- Mothers' status
- Work status

In addition to the trended figures, the latest RAMS release also includes two additional columns:

• After the % column (reflecting % of adults who listen to a particular station) is a +/- % column which indicates the possible range of this audience %, with a statistical certainty of 95%.

• After the '000 column (reflecting a station's audience in thousands) is a +/- '000 column which indicates the possible range of this audience figure, with a statistical certainty of 95%.
