Special Notices

Mediamark Research has been providing average issue audience information for magazines since 1979. These data, along with more extensive data on other media, demographic, psychographic and consumption data, are published every six months. 

In mid-2006, MRI began fielding a companion study to the National Study that moves beyond the average issue measure to provide audience information for each issue of a title. Based on the assumption that not every issue of a magazine yields the same audience size, this Issue Specific Study has as its primary objective the measurement of audience variability from issue-to-issue. Additionally, the Issue Specific Study is updated and released weekly to provide users with more up-to-date information on actual issues of a title.  For weekly magazines, these updated releases will likely include the audience for another issue of the magazine.  For other publication frequencies, new issue audiences will not be available for two weeks or more.

It is important to note, the Issue Specific Study is not intended to replace the MRI National Study as the audience currency. The Issue Specific Study is a companion to the MRI National Study and, in fact, works with this well-established study.

I.       Methodology

a.      Sample

The sample used for the Issue Specific Study is Survey Sampling International’s (SSI) Survey Spot Panel. As of June 13, 2007, the panel had a total of approximately 1.2 million members.[1]

The techniques that SSI uses to grow and maintain the Survey Spot panel are similar to those that other panel companies use. SSI creates a process that aims to limit bias and limit ineffective survey response/participation (i.e. fraud, etc.). SSI recruits Survey Spot panelists through thousands of websites and does not concentrate that recruitment among a limited number of sources.

SSI lists the Survey Spot membership restrictions in its “Summary of Panel Management Practices”. This document asserts that panelists must:

·        Have clearly and actively indicated their intention to join

·        Be 18 years of age or older

·        Have received a welcome message with the opportunity to opt out

·        Not be a duplicate of another panelist (based on email and postal address matching)

·        Possess confirmed validated data (geography and demographics) matched to postal address files and correct geographic assignment

·        Be assigned a unique panelist ID which is their identifier and can be used for deduping, recontacts and for post-survey analysis, if needed

·        Understand that survey participation through SSI panels will not serve as a means to supplement their income

·        Agree to keep confidential information such as new product concepts disclosed to them in surveys

SSI varies the rewards it issues for participation based on population segments. For example, younger members (18-24) receive small cash incentives for participation, while other segments receive no cash incentive but rather points or charitable donations.

b.      Demographic Breakdown: Survey Spot Panel Versus the National Profile

Comparing the demographic breakdown of the Survey Spot panel against the national profile (using data from the MRI Spring 2007 National Study) shows the limitations and biases associated with an Internet panel. For example, while the U.S. adult population (18+) is split 51.8% female and 48.2% male the corresponding sex split of the panel shows a greater skew toward females (74.7% female and 25.3% male).  

The following tables compare the U.S. demographic profile to that of the Survey Spot panel (as of June 9, 2007).

The Survey Spot panel is skewed younger than the general U.S. adult population. It should also be noted that .07% of the Survey Spot panel did not report their age, so there is a small amount of missing information.

While the proportion of individuals who are not employed is quite close, there are slightly more individuals who are employed part time on the panel compared to the U.S. adult population. Conversely, there are slightly fewer individuals who are employed full time on the panel compared to the U.S. adult population. Again, a small percentage of panelists have not reported their employment status.

The preceding table demonstrates that the panel is skewed in the direction of more education versus the overall U.S. adult population.

Back to Index

Missing household income data, 28.33%, among Survey Spot panelists are much greater than for other demographic variables. Comparing the available information with the MRI National Study data shows fewer individuals in the higher household income ranges than in the general adult population.

The disparities between the general population and the demographic make-up of the Survey Spot panel are undeniable. However, these disparities are consistent from week to week of the survey. It is important to remember that Internet panels, in general, are non- representative samples of the general population.

c.      Sample Selection Process

Every week on Tuesday, SSI selects a random national sample of panelists. This selection process includes the following parameters:

4,200 males 18-24

3,300 females 18-24

45,600 males 25 or older

34,400 females 25 or older

These panelists are screened against completed respondents (those who have completed an Issue Specific survey within the last six months).

Every Wednesday at 3 PM EST, SSI emails invitations for the Issue Specific Study to this pulled sample at a rate of 40,000 per hour (as will be discussed below, the survey opens every Wednesday at 3 PM).

Every Thursday, depending on the number of completes generated overnight, SSI either sends a reminder to the sample already invited and/or selects additional, supplemental sample. Supplemental sample is usually pulled for males only. The number of reminders and/or the size of the supplemental sample vary depending on the response rate from the first night (Wednesday) of data collection.

d.      Invitation

The MRI Issue Specific Study was first fielded on May 31, 2006. Data from this first field period through the May 24, 2007 field period comprise the first release of this study (this amounts to 52 weeks of data collection).

As detailed above, members of the SSI Survey Spot panel are invited to participate in the Issue Specific Study. Invitations are sent out via email every Wednesday at 3 PM EST. A copy of the two invitations is included in Appendix 2.[2] Embedded within the invitation email is a link to the online survey. Depending on the rate at which the survey is yielding completes, a reminder email may be sent out sometime on Thursday. This reminder email is identical to the original email invitation with only a change in the subject heading of the email from “Media Behavior Study” to “Reminder: Media Behavior Study”.

The survey is open from Wednesday afternoon each week until Thursday night. Around 2,500 completed surveys are obtained every week.[3] (See Appendix 3 for actual data on mail-out and cooperation rates.) The final number of invitations that are mailed out each week to generate that quota of completes varies. For example, in November/December of 2006 it was necessary to send out more invitations in order to complete 2,500 surveys. Evaluating all of the field weeks to date produces a cooperation rate range of between 1.60% and 3.58%. The average range of cooperation for the first 53 weeks of data collection is 2.83%.

Each week is an independent sample of completed surveys. Once a respondent has participated in the survey, he/she is not eligible to be invited back for six months.

e.      Questionnaire

The survey begins with the six-month screen question using black and white logos for each magazine as the recall stimulus. This procedure mimics the MRI National Study personal interview. Approximately 20 logos are placed on the grid on each screen. Logos are placed randomly within the grid each time the survey is started by a respondent. This ensures that every logo has an equal chance of being placed in every position of the survey. Respondents are asked to select which, if any, of the magazines, whose logos are on the screen, they have read or looked into in the last 6 months. There is a “none of the above” option given on each screen. A respondent must select at least the “none of the above” option on each screen in order to advance to the next screen.

Back to Index

Currently, the logos from the Wave 57 National Study field period are being used in the Issue Specific Study. All logos included in the National Study are included in the Issue Specific Study, excluding logos for the Spanish language titles and the airline titles. There are a total of 246 logos included in the study currently.

This is a screen shot of the first set of screens in the study (the six month screen question). Note, one cannot see the twenty logos on the screen shot above. Computers have different screen resolutions and sizes, so this may differ by computer. One can see the scroll bar on the far right-hand side of the screen shot that indicates there is additional information (i.e. additional logos) below. The “none of the above” option is found at the bottom of the logo grid box.

The Sunday magazines are included in the Issue Specific Study. In this study, the Sunday magazines are measured directly. These titles are found on a screen separate from the other magazines with a modified description. Randomization of the Sunday magazine logos is also conducted so that each title has an equal chance of appearing first in the grid or in any other position of the logo grid. At the outset of the study, there were a total of four Sunday magazines included in the study.  With the demise of Life Magazine, three Sunday supplements remain in the study.

Back to Index

Once respondents have indicated the titles they have read or looked into in the last six months, the survey proceeds to the issue specific section (see two example screen shots below). Respondents are shown the most recent covers for those titles they have identified as having read or looked into in the last six months. For weekly and bi-weekly titles, the respondent is shown the eight most recent covers. For tri-weeklies, monthlies and bi-monthlies, the respondent is shown the four most recent covers.

Covers are ordered from the least recent (left side of the screen) to the most recent cover (right side of the screen). Each cover is accompanied by its on-sale date. Additionally, the size of the covers has been maximized in order to give respondents the most information about the issue of the title. Therefore, on most covers, the respondent is able to read the major articles that are represented by headings on the cover.

There are magazines that produce split covers for all or particular issues. There are different types of splits: newsstand/subscriber, geographical, demographic, etc. MRI can only include one cover per issue in the study. Take the example of a newsstand/subscriber split in cover. If there is such a split in an issue(s) of a title, MRI requests that the magazine provide the cover representing the bigger proportion of its circulation (e.g., if the title has a bigger proportion of subscribers, MRI requests the subscriber cover in this case).

 Back to Index

In the case of geographical splits, MRI is currently exploring along with BUS Design, the company which programs the Issue Specific Study, a possible method of dealing with this issue. If it is possible to map the geographical split down to the zip code level, for example, and then link the particular cover for that geography, it may be possible to program a resolution to this split situation.

There are many different permutations of splits/cover treatments employed by magazine publishers. It is important that MRI shows the covers representing the largest percentage of the magazine’s circulation. In cases where this is impossible, there are implications for release of that given issue of the title (see release standards in Appendix 1 and list of non-released magazines and issues in Appendix 4).

In the issue specific section of the survey, the respondent is asked to select which, if any, of the issues shown on a screen they have ever read or looked into. Again, a “none of the above” option is provided to the respondent. And, the respondent must log in some data on each screen in order to advance to the next screen.

Back to Index

The screen shot above is an example of a screen for a weekly title. As established above, respondents see the eight most recent issue covers for weekly and bi-weekly titles. Every week, unless there is no new issue being published, the oldest cover drops out of the study and the new cover is introduced sending all the remaining covers down one position in the line. Weekly covers remain in the study for about eight weeks.

This second screen shot example is of a monthly title. Respondents see the four most recent issue covers for monthly, tri-weekly and bi-monthly titles. Similar to the example provided for the weeklies, the monthly covers are ordered from the oldest of the covers (far left-hand side of the screen) to the newest (far right-hand side of the screen). In the case of a monthly, approximately every four weeks (or upon the introduction of a new issue of the title) the oldest cover drops out of the study and a new one is introduced. Monthly covers remain in the study for approximately sixteen weeks.

Back to Index

The issue specific section of the survey is followed by two qualitative questions: the where read and how obtained questions. These questions are asked generically of a title rather than of each specific issue. These questions are asked generically so as not to create a burden for the respondent, thereby potentially having the respondent terminate the survey midway through,
invalidating the survey. (Only completed surveys are included in the 2,500 quota each week.)

The respondent may select both of the options if he/she so chooses. In the case where the respondent does select both options for this question, he/she is asked a follow-up question about where he/she reads or looks into the magazine most often. The respondent can only select one of the response options in the follow-up question.

Back to Index

Similar to the description of the “where read” question above, a respondent may select multiple response options for the “how obtained” question. In cases where multiple responses are selected, the respondent is asked a follow-up question to determine where he/she most often obtains the copy of the title.

The respondent is then asked two Internet related questions: how often he/she uses the Internet in a week and where he/she is taking the survey. Finally, the survey ends with a series of demographic questions:

·        Sex,

·        Age,

·        Marital status,

·        Employment status,

·        Education,

·        Household income[4],

·        Race[5], and

·        Hispanic.

The survey takes on average about twelve minutes to complete.

II.       Results and Analysis

a.      Weighting

The following variables were used for the standardization of the Issue Specific data. MRI used the average of the first twenty weeks of data collection to develop these standardized targets for each variable. Standardizing the weights provides consistent demographic profiles for each week’s sample without substantially impacting the effective sample size of the study. All variables were standardized within sex. 

·        Hispanic Origin

·        Race

§         White only

§         Not White only

·        Household Income

§         Under $25,000

§         $25,000-$49,999

§         $50,000-$74,999

§         $75,000-$99,999

§         $100,000 or more

§         Prefer not to say

·        Education

b.      Examples of data spreadsheets

The following data tables depict how MRI sees the data generated in the Issue Specific Study. The week-to-week index information shown here is not included
 in the deliverable; only the final indices found on the far right of each table (in the gray shaded column) are shown. The final index is an average index for a given issue across all the weeks that this issue was in the field.

The first example is for a weekly magazine.

Table 1

Example of Data Input for Weekly Magazine

Table 1 shows indices for each of 10 issues of a magazine over 8 weeks.[6] After eight weeks in the field, MRI can compute 8 independent indices for each issue, representing the issue’s relative performance against all other issues of the magazine during that period.  These replicated comparisons provide a robust database for producing issue specific information.  For example, issue 1 produced an average index of 121. Compared with all other issues for this title, this issue did 21% better than average. Note that, in a substantial majority of instances, issues that do well tend to do well across all or close to all of the weeks in the comparative database. For issue 1, six out of the eight weeks demonstrated much higher indices than average. The same can be said of Issue 7 which produced a final index of 139. Conversely, the same consistency is found when issues do worse than average.  Issue 3, for example, produced a final index of 80, and had seven out of the eight weeks of measurement yielded indices under 100, as well.

Back to Index

The second example, below, is for a monthly magazine.

Table 2

Example of Data Input for Monthly Magazine

This example shows much the same as the example of the weekly magazine. There are cases where an issue over performs in respect to the average (e.g. Issue 4). Again, when an issue does better than average it tends to do so over the majority of weeks in the field. In the case of Issue 4, ten weeks out of ten produced higher than average indices. Similarly, if an issue performs worse than average, Issue 9, it does so consistently. In the case of Issue 9, nine measures out of ten consistently under performed from average.

c.      Approaches to Modeling

As is described in detail elsewhere, the input data for estimation process to determine the relative issue-to-issue is based on successive week samples of approximately 2,500 persons.  For weeklies there are 8 successive weekly samples for each issue and for monthlies there are 16 successive weekly samples.  The basic sample of 2,500 is weighted on the basis of all demographic variables each week.

For the i^th magazine, the relative weekly measurement RWM for the k^th relative week across all of the issues (j=1,…J) extracted.  A mean, standard deviation and coefficient of variation are computed for the each of the K relative weeks.  Let CV(i,k) denote the observed coefficient of variation for k^th relative week of the i^th magazine.

For the k^th relative week of the i^th magazine, we compute the probable coefficient of variation PCV(i,k).  This probable coefficient of variation is computed under the assumption that there is “no variation” in the actual audience of the i^th magazine at the k^th relative week of issue life.

Back to Index

Finally by subtracting the probable coefficient of variation from observed coefficient of variation we obtain ISCV(i,k) the issue specific coefficient of variation for the k^th relative week of the i^th magazine.  These issue specific coefficients of variation are averaged over the k included weeks.  This average produces ISCV(i) the issue specific coefficient of variation for the i^th magazine.

Within each of the k relative weeks each of the means for the various issues are converted into indicies.  These indicies are averaged across the various included weeks to produce an initial issue specific index value.   Let INDX(i,j) denote the initial average index for the j^th issue of the i^th magazine.  Using a power transformation SINDX(i,j) = INDX(i,j)^p, we solve for p so that the coefficient of variation of the resulting SINDX(i,j) values is equal to ISCV(i)

d.      The MRI National Study and the Issue Specific Study

As asserted above, the Issue Specific Study is not intended to replace the MRI National Study. Rather, the two studies work together. In effect, the Issue Specific Study introduces the variability from one issue to another using the average issue audience from the National Study as the base to demonstrate that variability.

Average issue data by title from the National Study are used as references for the Issue Specific data. Once an issue is tied to a reference National Study, that reference is never changed. For example, all issues released in the first Issue Specific release (June 19, 2007) will be referenced to the Spring 2007 National Study. Once the Fall 2007 National Study is released, it replaces the Spring 2007 as the reference. Every issue released in the Issue Specific Study subsequent to the Fall 2007 release will be referenced to the Fall 2007 National Study. Those issues that were released prior to the release of the Fall 2007 will always remain referenced to the Spring 2007.

From the Issue Specific Study, MRI establishes an index[7] for each issue of every released title. This index represents the performance of that given issue in respect to other issues of that title (indices substantially over 100 are those that perform better than average, those substantially below 100 are those that perform worse than average, and those around 100 perform about average).

In general, a twelve-month aggregation of issue specific data will serve as the reference baseline for the initial and subsequent six months of measured issues in the Issue Specific Study. Every six months, consistent with the release of the new MRI Fall or Spring National report, a new baseline is created by dropping the oldest six months of issue specific data and replacing them with the most recent six months of collected issue specific data. Therefore, MRI generates issue indices against a baseline of data collected during the same period of interviewing in the National Study.

Back to Index

Multiplying the index and the average issue audience from the National Study produces the issue audience for each issue (this is done for total adult, male and female using the average issue audiences from the National Study for each of the three groups).

For example, a hypothetical weekly magazine (MAGAZINE A) has a 20 million audience in the Spring 2007 National Study. Let’s assume this magazine had an issue (ISSUE 1) that over performed and produced an index of 120 in the Issue Specific Study. The issue audience would be calculated in the following way:[8]

                                                                   X                           =

e.      Deliverable

The initial deliverable is provided online. Users are given username and password information in order to log into the online spreadsheet. The spreadsheet includes indices for adult, male and female. Additionally, the spreadsheet will publish the issue audience for each released issue (the calculation of which is demonstrated above in the box).

The male and female indices come directly from the Issue Specific Study. Male and female issue audiences are calculated using these indices. The total adult issue audience is calculated by summing up the male and female issue audience. Finally, the total adult index for an issue is calculated by dividing the total adult issue audience by the total adult average issue audience figure from the MRI National Study.

In order to enhance the data provided, each magazine cover is linked within the spreadsheet as a reference for the user.

The first release will include data for total adults, male and female for each released issue by title (see Appendix 4 for titles and issues not released). In the future, MRI will evaluate the release of additional demographic data such as age, income, and education.

III.       Disclaimers

(1)  Non-responding and non-reporting persons may have media habits which differ from those of respondents.  Therefore, non-responding persons and other limitations in the original sample may create additional bias in data.

(2) The sample, sample design and /or response patterns may preclude proportional representation of certain groups within the population such as ethnic groups, racial groups, persons in certain income or education groups or persons whose primary language is other than English.  Such persons may have media habits which differ from other persons.

(3) Human and computer processing errors may occur before or after Mediamark Research Inc receives the survey data. .

(4) Defects and limitations found in data and covers supplied by others (e.g., Survey Sampling Inc., clients sending covers, etc.) are inherent in MRI estimates based thereon.

Appendix 1: Modeling/Release Standards

DATE: JUNE 19, 2007

There are two levels of release evaluated for the Issue Specific Study. First, does a magazine meet the requirements for release? Second, if the magazine is released, do all the issues of the magazine meet the requirements for release? There is an interplay between these two levels of assessment in that, for example, if not enough data are present to release a minimum number of issues of a potentially released title, that title will not be released. The release standards are as follows:

1.      MRI will use Spring 2007 as the reference period for all magazines. If a magazine is not released in the Spring 2007 report, it cannot be released in the Issue Specific study.

2.      MRI is freezing the analysis for the first release as of May 31, 2007. 

3.      MRI cannot include magazines in the service if they have less than 4 issues that can be delivered at the reporting date and/or if the reference period for the data begins after August 2006.[9]

4.      MRI must remove all known split cover issues that were not handled properly, frequency change magazines and magazines with inconsistency execution of split covers from reporting.[10]

5.      Magazines not released in the first report are not available for release review until November (with the fall release).

If a magazine meets initial requirements for release, its data will be modeled for release. Certain principles guide the modeling of the Issue Specific data:

1.      Each issue must have a minimum 5 weeks of measurements for weeklies

2.      Each issue must have a minimum 8 weeks of measurements for bi-weeklies, tri-weeklies, monthlies and bi-monthlies

3.      MRI cannot have more than 25% of a day missing to be included

4.      For weeklies, 56 days are used as a maximum period for comparison.

5.      For bi-weeklies, 70 days are used as a maximum period for comparison. 

6.      For tri-weeklies, 78 days are used as a maximum period for comparison.

7.      For monthlies, 85 days are used as a maximum period for comparison.

8.      For bi-monthlies, 120 days are used as a maximum period for comparison.

9.      MRI cannot model later weeks for an issue; only recent issues that have met a days old requirement completely (no modeled numbers at the end) can be included

10. MRI will trim all indices at 72 and 140.

If an issue of a released title violates any of these modeling rules, it cannot be included in the model (and is thereby not released). This, in turn, may have implications for the release of the title (if too many of the issues have to be suppressed for violating these rules, for example).

Appendix 4: titles and issues not published

The following is a list of items not published in the first release of the MRI Issue Specific Study. This list includes whole titles where no data is being released. A magazine title listed below without any date information is not released at all.

The list also includes specific issues not released for titles that are otherwise released (this is noted when the title is followed by a date(s)). The rationale for not publishing information for the listed issues can be found on the deliverable. It should be noted that MRI is dependent on client information regarding the presence of a split cover. It is possible that there are issues of a title released in the Issue Specific Study that were, in fact, split and should not be released. In such cases, it is important for the client to let MRI know as soon as possible so that we evaluate the situation and make a decision about the issue data.
