A frequent question is why there is such a range of different readers-per-copy estimates, particularly for publications which appear to have much in common.
The relationship between readership and circulation is notoriously difficult to unpick. There are many factors involved, some of which may work together and some in opposite directions. The content and characteristics of a publication will play their role, but probably the most important single factor is the opportunity for pass-on readership outside the home.
The potential for pass-on readership outside the household
The potential for pass-on readership by people other than whoever originally obtained the copy is central to the number of RPC. A high number of pass-on readers translates into a high RPC. The starting point for any investigation into RPC is therefore ‘source of copy’, particularly the proportion of readership that takes place outside the home.
A copy which is delivered to the home and never leaves the home only has the potential to be read by adults living in that household, and any visitors there may be.
On the other hand, a copy which is in a public place – e.g. an office, a library, a hair salon, or a café – has the potential to be read by many more adults. If the copy is taken out and about – to work, shown to a friend, left on a train, etc. – this also gives the opportunity for pass-on readership and additional readers-per-copy.
Two publications may have very similar content, pricing and reader profiles, but if one is more freely available in public places, that is likely to make a difference to their relative RPCs.
NRS collects some information on source of copy, including whether the reader has obtained their own copy, seen it within their own household, read someone else’s copy, or seen a copy at work, in a public place or somewhere else. This is valuable information in starting to understand RPCs.
However, not all public place reading is equal. Some locations and situations will generate significantly more pass-on readership than others. It might just be one or two additional RPC – and it might be very many indeed, with the effect of increasing the overall average RPC. A study of outof-home reading in the United States found that public place copies generated on average 30 readers per-copy, and as many as 50 in some locations.
If publishers are using marketing strategies which increase the likelihood that the publication will be available in public places with a high potential for pass-on readership, this too can have an impact.
Household size and profile
For copies that are kept within the home, household sizes will be relevant to RPC. The average household size in Great Britain is 2.35 adults aged 15+ per household, and over time this has been falling with an increase in single person households. However, differences in the average household size for readers of individual publications tend to be overshadowed by any differences in out-ofhome reading.
Demographics and lifestyle may also be relevant, particularly if they mean that the publication is more likely to be shared outside the home. For instance, workers may be more likely to take copies out of the home and pass them around in their workplaces, those with a wide circle of friends and social activities may be more likely to share content, and so on.
Pricing and promotions
Pricing and promotions are other factors to consider, particularly when they influence the availability (and perceived availability) of the publication.
If a publication is free (or low cost) and everyone can get their own copy if they want, this can result in a low RPC as there is no need to read someone else’s copy.
Zero or low cost may also affect perceptions of the publication. Because there is no significant cost attached, the publication may be perceived as relatively disposable. If so, this doesn’t necessarily mean that it is not actively acquired and enjoyed by the initial reader, it is just that there are likely to be fewer opportunities for pass-on readership.
Price cuts and promotions such as gifts, cover mounts and competitions may also have a negative effect on reader-per-copy. This is because previous pass-on readers are encouraged to buy their own copy, thereby reducing the pool of pass-on readers, at least temporarily.
On the other hand, while high cover prices may be less of an inhibitor to owning one’s own copy than they once were, in some cases they may still encourage sharing, or extend the life of a publication.
The competitive situation
The competitive situation may also have a bearing on RPC. If one publisher is having a promotion, advertising heavily, or launching a new title, this may take readers from the pool of pass-on readers for a similar title.
New titles launched into an already busy market sector may find they struggle to develop pass-on readership and do not reach the RPC levels of more established titles. Established titles may see their RPCs fall as their sector becomes saturated.
As will be apparent, there are a wide range of factors affecting RPC, some of which it is possible for the publisher to influence, and others less so.
NRS can provide some clues as to what is happening – by looking at the long-term trends for RPC and the source of copy data. The complexity of the relationship between readership and circulation means that it is usually not possible to establish all the factors involved in a specific situation, and their relative importance.
However capturing the differences in RPC is the reason why a readership survey is vital to give a measure of the true reach of each publication, which circulation data alone cannot do.
