So we do know a fair amount which groups are the biggest or smallest police in various areas do have an idea of numbers in street prostitution and this is much smaller than those working indoors (in massage parlours, saunas, agenicies or independently etc). Other sources are information are the numbers who engage with support services here also information from counting prostitutes advertisements here and here, plus we do have estimates of the number of clients of prostitutes from NATSAL surveys here.
Thank you for the links. They are all PDF files and for safety sake I never download PDFs and always view them via the archive.
Your first link is to a PDF file located at
eprints.bbk.ac.uk/17962/1/17962.pdf
It does not work in the wayback machine or at the archive. I am not sure why. Can you C&P the relevant text here?
Your second link is to this document
Project Acumen
Setting the Record:The Trafficking of Migrant Women in England and Wales off-street prostitution sector
August 2010

I have not read it all but noticed the caveat on page 10, which I did read and which explains that "in some areas it [the report] may deviate from conventional academic research methods and standards. The report utilises statistics in a variety of ways throughout, but should not be viewed as a statistical report in the classical sense; rather as an inessential analysis which draws on statistics where appropriate.”
Further caveats follow
It may very well be a valuable document that can provide some insights into some aspects of what it calls “off-street prostitution”, however the report includes, quite correctly, caveats as to the limited and provisional nature of the data and conclusions published. I will sit down and read it all carefully when i have a moment and report back.
Your 3rd link is a duplicate of the 2nd
Your 4th link is to a BMJ paper titled "
The prevalence of, and factors associated with, paying for sex among men resident in Britain: findings from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3)"

I am a little confused as to what the relevance of the paper is to our current discussion. I skim read it and while it reported interesting data in relation to men who pay for sex (MPS) one of the most interesting findings (for me at least) was that the majority of MPS reported paying for sex in foreign territories, as sex tourists, rather than in the UK, thus somewhat compromising the ability of the paper to report on trends within the UK sex industry.
Your 5th link looks interesting and the conclusions drawn seem entirely reasonable. Anyone with even the most rudimentary and provisional understanding of how sex workers market themselves appreciates that photos, descriptions, ages, and all manner of other information used to market the sex worker are more often than not wildly inaccurate. Researchers posing as customers or harvesting data from websites advertising sexual services are unlikely to harvest useful data for this reason.
I admit I have not sat down for a few hours to study all the material in your links I have skim read the ones I could access.
The conclusions I have gained from doing so are that, while some researchers can provide some provisional conclusions some of the time, there are many unhelpful rabbit holes researchers can fall into if they are not careful that are likely to result in wildly inaccurate reporting.
This makes sense to me and I would not disagree with it. I will take another look at the documents when i have a moment, however it seems to me that none of these documents claim to provide authoritative data or conclusions as to the exact numbers of people working in any particular aspect of the sex industry.
Having said this I suspect that your claim that there are far more people working off-street than on a typical prostitution “beat" is likely to be correct, however there are further difficulties and complexities that render it pretty much impossible to gain accurate data regarding numbers.
Some of these challenges have been noted in your links.
There is an additional difficulty inasmuch as there are various kinds of transactional sex that may or may not be considered to be sex work by either the parties involved or by outside observers. Sugar daddies, sugar mummy, sugar babies, mistresses, courtesans, “arrangements”, sex in exchange for rent, survival sex, there are many varied and complex forms of transactional sex that are unlikely to be included in any research.
Some are at the more privileged end of the continuum, e.g. courtesans, some, survival sex are at the most disempowered. However, regardless of the level of financial remuneration the power imbalance between the person providing renumeration and the person receiving it I think a centrally important factor in determining the likelihood of abuse and exploitation.
