Labour Market Information (LMI) is not perhaps the most popular subject to talk about. But with the advent of open and linked data, LMI is increasingly being open up to wider audiences and has considerable potential for helping people choose and plan future careers and plan education programmes, as well as for use in research, exploring future skills needs and for social and economic planning.
This is a video version of a presentation by Graham Attwell at the Slovenian ZRSZ Analytical Office conference on “Short-term Skills Anticipations and Mismatch in the Labour Market. Graham Attwell examines ongoing work on mid and long term skills anticipation in the UK. He will bases on work being undertaken by the UK Commission for Employment and Skills and the European EmployID project looking, in the mid term, at future skills needs and in the longer term at the future of work. He explains the motivation for undertaking these studies and their potential uses. He also explains briefly the data sources and statistical background and barriers to the wok on skills projections, whilst emphasising that they are not the only possible futures and can best serve as a a benchmark for debate and reflection that can be used to inform policy development and other choices and decisions. He goes on to look at how open and linked data is opening up more academic research to wider user groups, and presents the work of the UKCES LMI for All project, which has developed an open API allowing the development of applications for different user groups concerned with future jobs and future skills. Finally he briefly discusses the policy implications of this work and the choices and influence of policymakers in influencing different futures.
Only yesterday John Naughton, in an article entitled “We are ignoring the new machine age at our peril“, worried about the impact of self driving cars and other technology on the future of employment. Naughton argued that there are “radical discontinuities that nobody could have anticipated”, driven by “combinatorial” effects of different technology trends coming together. These, he siad, include: “the near-infinite computing power provided by Moore’s law; precise digital mapping; GPS; developments in laser and infrared sensor technology; and machine-learning algorithms plus the availability of massive data-sets on which to train them.”
He warned the outcome could be “that vast swaths of human activity – and employment – which were hitherto regarded as beyond the reach of “intelligent” machines may now be susceptible to automation.” he went on to quote a studyby Dr Carl Benedikt Frey and Michael Osborne, two researchers at the Martin School in Oxford,T heir report, The Future of Employment: How Susceptible Are Jobs to Computerisation?, estimates the probability of computerisation for 702 detailed occupations, based on US government classifications of those occupations. About 47% of total US employment, they conclude, is at risk from technologies now operational in laboratories and in the field.
However a study entitled ‘Are ICT Displacing Workers? Evidence from Seven European Countries‘ by Smaranda Pantea, Federico Biagi and Anna Sabadash from the Institute of Prospective Technologies in Seville comes up with a different answer. Looking at micro data ins even European countries for companies in the manufacturing, ICT producing and service sector the study found “a non-significant relationship between employment growth and ICT intensity among ICT-using firms.: The authors say: “Since our estimates mainly capture the “substitution” effects of ICT on employment (i.e. those due to ICT substituting for some type of labour and to ICT increasing productivity and hence reducing demand for inputs, for constant values of output), our results indicate that these effects are statistically insignificant.”
Of course this study and the American study are not directly comparable. They looked at different things and used different methodologies. One conclusion might be that whilst technology is not being directly substituted for overall employment, it is changing the nature of jobs available. Some labour market studies (for instance based on the US O*Net surveys) have suggested that what is happening is a bifurcation of labour, with an increasing number of high qualified jobs and of low skilled (and consequently low paid) service sector jobs. And of course another impact may be on the ;content’ and different skills required in different jobs. For instance our work in the construction industry through the Learning layers project suggests increasing adoption of technology is leading to the need for new (and higher) skills levels within what was traditionally seen as a lower skills sector. This has considerable implications for vocational education and training. ather than training for presents skills demands VET systems need to be looking at future skills. And by providing those future orein3eteds kills this could provide a workforce and society with the abilities and motivation to shape our use of technology in society, rather than as John Naughton fears that “we’re bound to lose this race against the machine” and in the course “enrich the corporations that own it.”
As promised, a post on our stand and presentation at Alt-C on the LMIforAll Labour Market Data project, sponsored by UKCES. Working together with the Institute for Employment Research at Warwick University and Raycom, we have developed a database and APi providing access to a range of data about a wide variety of different occupations in the UK including data about:
The API is self documenting and is available free of charge to both for profit and not for profit organisatio0ns and developers. Working with Loud Source we have run a competition for Apps built on the API and together with Rewired State we have organised a series of Hack Days and Mod Days. We are currently redesigning the website to provide better access to the data and to the different applications that have been built to date.
One strange thing that took people visiting our stand some time to understand was that we were not selling anything (I think ours and Jisc were the only non commercial stands). The second thing was that we were not trying to ‘sell’ them a shiny out of teh box project. To get added value from our database and API requires some thought and development effort on the part of organisations wanting to use the data. We provide the tools, they provide the effort to use them. But when people got that concept they were enthusiastic. And most interestingly they were coming up with completely new ideas for where the data might be valuable. As you can see in our presentation above, we have largely focused on the use of LMIforAll for careers planning. University and Further Education researchers and developers saw big potential using the API as a planning too for future courses and curriculum. Others saw it as a valuable resource for measuring employability, a big agenda point for many UK institutions. It was also suggested to us that the labour market data could be mashed together with data derived from learning analytics, providing possibly a more learner centred approach to analytics than has previously been deployed.
If you are interested in any of these ideas have a play on the LMIforAll web site. And feel free to get in touch if you have any questions.
Technology Enhanced Learning, at least form a research perspective, has always tended to be dominated by the education sector. Coming from a background in vocational education and training, I was always more interested in how technology could be used to enhance learning in work and in particular informal learning in Small and Medium Enterprises.
Much early work in this area, at least in Europe was driven by a serious of assumptions. We were moving towards a knowledge economy (remarkable how quiet that has gone since the economic crash) and future employment, productivity and profitability, required higher levels of skills and knowledge win the workplace.. Prior to the rise of the World Wide Web, this could be boosted by enhancing opportunities for individual learning through the development of instructional materials distributed on disc or CD ROM. Interestingly this lead to much innovative work on simulation, which tended to be forgotten with the move to the online environment offered by the World Wide Web.
One of the big assumptions was that what was holding back learning in enterprises was the cost of releasing employees for (formal) training. Thus all we had to do was link up universities, colleges and other training providers to enterprises through providing courses on the web and hey presto, the problem would be solved. Despite much effort, it didn’t really work. One of the reasons I suspect is that so much workplace knowledge is contextually specific and rooted in practice, and trainers and particularly learning technologists did not have that knowledge. Secondly it was often difficult to represent practice based knowledge in the more restricted learning environment of the web. A further issue was a failure to understand the relationship between learning nd professional development, work practice and professional (or occupational) identities. That latter issue is the subject on a paper entitled Facilitating professional identity formation and transformation through technology enhanced learning: the EmployID approach, submitted by my colleagues from the EmployID reject, Jenny Bimrose, Alan Brown, Teresa Holocher-Ertl, Barbara Kieslinger, Christine Kunzmann, Michael Prilla, Andreas P. Schmidt, and Carmen Wolf to the forthcoming ECTEL conference. Their key finding is that there is “a wide spectrum of how actual professional identity transformation processes take place so that an ICT-based approach will not be successful if it concentrates on prescribing processes of identity transformation; rather it should concentrate on key activities to support.” They go on to say that “ this is in line with recent approaches to supporting workplace learning, such as Kaschig et al. (2013) who have taken an activity-based approach to understanding and supporting collective knowledge development.”
The following short excerpt from the paper explains their understanding of processes of professional work identity formation:
“Professional work identities are restructured in a dynamic way when employees are challenged to cope with demands for flexibility, changing work situations and skill needs (Brown, 1997). The work activities of practitioners in Public Employment Services (PES) need to be trans- formed due to the changing nature of the labour market. As their roles change, so do their professional identities. Work identities are not just shaped by organisations and individuals, but also by work groups (Baruch and Winkelmann-Gleed, 2002) or communities of practice (Lave and Wenger 1991; Brown, 1997; Ibarra, 2003). PES practitioners in particular need to develop multi-dimensional (individual and collective) professional identities to cope with socio-economic and technological change (Kirpal, 2004). This shift is underpinned by the increased importance of communica-tions skills, a willingness to engage in learning and reflexivity, while reflection on experience over time may be particularly significant in the build-up of implicit or tacit knowledge as well as explicit knowledge (Eraut, 2000). At the individual level, emerging new demands and associated skills shifts generate a potential for conflict with traditional work orientations and associated values, norms, work ethics and work identity patterns of employees. One important focus for support are individuals’ strategies for dealing with such conflicts. While any identity formation process has to be realized by the individual, the process of acquiring a work identity also takes place within particular communities where socialization, interaction and learning are key elements. Therefore, supporting networks, of ‘new’ communities of practice (Lave, 1993; Wenger, 1998; Billett, 2007) and feedback from other practitioners are important aspects on which to focus.”

First the official stuff (from the press release).
“Talented UK students have won three out of four prizes in a worldwide competition to create a new app to help people develop their career.
The CareerHack open data contest was launched in November last year by the UK Commission for Employment and Skills (UKCES), and asked developers around the globe to build an app based on the UK Commission’s “LMI for All” open data, which contains information on the UK labour market, including employment, skills and future job market predictions.
First prize winner for the competition was Tomasz Florczak from Logtomobile in Poland, who won £10,000 for his innovative Career Advisor app, while 16-year-old school student Harry Jones, from Bath, took home a £5,000 prize for his Job Happy entry.
The contest also had a special prize specifically for entrants aged 16-24 in Further Education. In this category 22-year-old IT apprentice Phillip Hardwick won the £5,000 prize for his entry, Career Path. And judges were so impressed with the quality of entrants from the category that they introduced an additional runner-up prize of £2,500, which went to a team effort from students at Barking and Dagenham College in London.
Competition judge Dr Deirdre Hughes OBE, Chair of National Careers Council and a Commissioner for UKCES, said:
“As judges we were all highly impressed at the outstanding contributions made by our winners, and of the talent and ability being displayed by the next generation of up-and-coming developers and programmers.
“The quality of the submissions was so high we felt the need to introduce an additional prize, but all those that entered should be extremely proud of their efforts.”
The judging panel was made up of technology experts from Google, Ubuntu and HP, alongside representatives from the UK Commission and John Lewis. Judges made their decision based on how innovative the entry was, how viable it was as a working app, the potential it had for making an impact on society and the overall quality of the packaged app.
CareerHack judge Matt Brocklehurst, Product Marketing Manager at Google UK said:
“At Google we’re well aware of the importance of making data open and encouraging young, creative talent. CareerHack was a fantastic example of this and we were very impressed by the high standard of entries from everyone who entered – the fact that three of the four winners are young people at the start of their careers is fantastic news. We hope these prizes will enable them to get a head start down whichever career path they choose to follow.”
Fellow CareerHack judge Cristian Parrino, Vice President of Mobile and Online Services at Ubuntu, added:
“The CareerHack competition demonstrated how an set of open data can be used to cater to the needs of people at different stages of their career paths. It was wonderful to see the different flavours of high quality applications and services built on UKCES’s data.”
LMI for All has been developed by the UK Commission for Employment and Skills, working with a consortium led by the Institute for Employment Research at Warwick University and including Pontydysgu, RayCom and Rewired State.”
Pontydysgu’s bit in all this is managing the technical side. I have to say I was a bit sceptical of producing an APi and then opening it up and encouraging contributions through a competition, but having looked at the videos I am gobsmacked by the inventiveness of teh programmers who entered. We will be looking in more depth at what has been produced. We are also seeking feedback from all those who participated and planning more events later in the year. If you would like to know more (and particularly we would be interested in similar approaches to Open data for Labour Market Information in other countries) please contact me at graham10 [at] mac [dot] com.
I don’t normally post press releases on this site. Too much corporate speak. But I make an exception in this case. Regular readers will know that for the last three years I have been playing with the possibility of using open data for people to make choices about their future jobs and careers – whether it be moving to a new area to seek work, changing careers or selecting a university or college course. For the past two years we have been working with Warwick University and Raycom on the UK Commission for Education and Skills sponsored LMI for All project. the project has developed a database and APi providing access to a range of Labour Market Information. The work has proved challenging in terms of negotiating access to different data sets, ensuring the data is non disclosive and cleaning the data and in developing the technical infrastructure to provide easy access but at the same time ensuring the security of the data.
The beta vesrion of the APi was released in June this year. Whilst we provide access to a web based data explorer we do not provide apps. Instead the idea os to Over the autumn we have been upgrading the infrastructure and adding more datasets including the US O*Net data. Whilst we provide access to a web based data explorer we do not provide apps. Instead the idea to encourage third party developers, including careers web sites, to themselves develop web and mobile applications based on the API. And yesterday UKCES, working together with together with Loudsource have launched a CareerHack competition for apps based on the API.
The press release says:
A NEW competition launched today is calling on developers from across the globe to create an app to help people hack into a new career and win a share of £20,000 in the process.
The CareerHack contest, run by the UK Commission for Employment and Skills (UKCES), is asking developers to find innovative and inspiring ways of using data made available through its LMI for All data site. This is a unique portal containing Labour Market Information (LMI) on employment, skills and future job market predictions, which for the first time makes the different sources of information compatible with each other and available in the same place.
The winner will be given £10,000 to spend as they wish, with £5,000 going to the runner-up. A special £5,000 prize is available to college students aged 16-24, giving the opportunity for the tech-leaders of tomorrow to showcase their talents and skills.
Michael Davis, Chief Executive of UKCES said:
“We wanted to find a way to allow as many people as possible to benefit from our open data approach to careers and jobs intelligence. An open innovation contest for developers is the perfect solution and we’re delighted that there is a special category for young people studying in college. I’m looking forward to seeing the creativity of app developers from across the world.”
The LMI for All data portal brings together extensive careers intelligence providing a single point of access to the data needed to answer common career questions such as how many people currently work in a particular job, average salaries and the skills needed for certain careers or roles.
While LMI for All information is already being used in various ways by a number of websites, organisers hope the CareerHack contest will open the resource up to creative individuals from around the world – uncovering new and innovate ways to use data to help people map out their future career.
To help illustrate the ways in which the information can be used a Career Trax website has been created by the UKCES – highlighting just one of the ways the LMI for All data can be used.
All entries must be submitted with a brief YouTube video, showcasing how the app works and illustrating its potential. A panel of judges, including representatives from Google and Ubuntu, Further Education institutions and business leaders, will then pick the overall winner next February.
Both individuals and teams are eligible to enter. You will need to be capable of developing a workable app using LMI for All data. For more information, please visit the contest website at http://careerhack.appchallenge.net
The closing date for entries is 5pm on Friday the 21st of February 2014.

Last week I wrote about projections of future demand for Science, Technology, Engineering and Maths (STEM – or in Germany – MINT) occupations. I suggested that predictions of skills shortages were overstated.
The same applies to computer programmers. According to the European Commission, “many vacancies for ICT practitioners cannot be filled, despite the high level of unemployment in Europe. While demand for employees with ICT skills is growing by around 3% a year, the number of graduates from computing sciences fell by 10% between 2006 and 2010.
If this trend continues, there could be up to 900 000 unfilled ICT practitioners’ vacancies in the EU by 2015.”
This is not the first time the European Commission has predicted skills shortages for ICT practitioners. Prior to the Millennium bug, there were once more predictions of a massive shortage of programmers. And I suspect, with a little internet searching, it would be possible to find annual predictions of skills shortages and unfilled vacancies, especially from industry lobby bodies.
One reason for this, I suggested in my previous article, is that the ICT industry has an interest in keeping wages down by ensuring an over supply of qualified workers. In this respect, a report last week on the size and value of the apps industry in Europe is interesting. The report published by industry trade body ACT, claimed that there are currently 529,000 people in full-time employment directly linked to the app economy across Europe, including 330,000 app developers with another 265,000 jobs n created indirectly in sectors like healthcare, education and media, where apps are increasingly prominent.
At first glance then, this is a rosy area for young people with a good future. But digging deeper into the data suggests something different. According to the Guardian newspaper, “In the UK specifically, the report claims that 40% of organisations involved in developing apps are one-man operations, while 58% employ up to five people. It also points out that 35% of UK app developers are earning less than $1,000 a month from their work.”
1000 dollars a month is hardly a living wage, let alone a sufficient level of remuneration to justify the expense of a degree course. However this does not discourage the industry group who amongst other measures are lobbying the European Commission to strengthen the single market and develop “a flexible and supportive business environment for startups and entrepreneurs.” In other words, more deregulation.
There are a number of problems in looking at skills shortages in this area. My suspicion would be that although the numbers graduating from computer science have fallen, graduates in computer and ICT related courses has risen. And demand for ICT practitioners covers a wide range of occupations. Rather than increasing the number of computer science graduates, more useful would be to ensure that ll graduates are skilled in designing and using new technologies. Of course developing such skills and competences should start at a much younger range. It is encouraging the ICT has been included in the primary school curriculum in England from next year.
The EU policy on future employment is based on the idea of job matching – of trying to match skills, qualifications and vacancies. Of course this does not work. What they should be doing is looking at prospective competences and skills – at giving young people the educations and skills to shape the future of workplace3s and employment. That could include the ability to use technology creatively in a socio-technical sense. But of course that would not suit the various industry lobby groups who are more concerned with protecting there profits than shaping the future of our society.
The debate over skills shortages is looming again. For some years national governments and the European Commission have been warning over shortages of qualified workers in Science, Engineering, Technology and Maths (STEM) . Yet a number of studies refute these claims.
A blog post on SmartPlanet quotes Robert Charette who, writing in IEEE Spectrum, says that despite the hand wringing, “there are more STEM workers than suitable jobs.” He points to a study by the Economic Policy Institute that found that wages for U.S. IT and mathematics-related professionals have not grown appreciably over the past decade, and that they, too, have had difficulty finding jobs in the past five years. He lists a number of studies that refute the presence of a global STEM skills shortage. The U.S. Bureau of Labor Statistics, for one, estimates that there was a net loss of 370 000 science and engineering jobs in the U.S. in 2011.
I doubt that figures in Europe would be much different. One of the issues is how to define a ‘STEM” job. In the UK jobs are classified through a system called Standard Occupational Classification. This itself has its problems. Given the desire for comparability, SOC is only updated every ten years (the last was in 2010). In a time of fast changing occupations, it is inevitably out of date. Furthermore jobs are classified to four digits. This is simply not deep enough to deal with many real occupations. Even if a more detailed classification system was to be developed, present sample sizes on surveys – primarily the Labour Force Survey (LFS) would produce too few results for many occupations. And it is unlikely in the present political and financial environment that statistical agencies will be able to increase sample sizes.
But a bigger problem is linking subjects and courses to jobs. UK universities code courses according to the Joint Academic Coding System (JACS). It is pretty hard to equate JACS to SOC or even to map between them.
The bigger problem is how we relate knowledge and skills to employment. At one time a degree was seen as an academic preparation for employment. Now it is increasingly seen as a vocational course for employment in a particular field and we are attempting to map skills and competences to particular occupational profiles. That won’t really work. I doubt there is really a dire shortage of employees for STEM occupations as such. Predictions of such shortages come from industry representatives who may have a vested interest in ensuring over supply in order to keep wage rates down (more on this tomorrow). For some time now, national governments and the European Union, have had an obsession with STEM and particularly the computer industry as sources of economic competitiveness and growth and providers of employment (more to come about that, too).
However, more important may be the number of occupations which require use of mathematics or programming as part of the job. One of the problems with the present way of surveying occupational employment is that there is an assumption we all do one job. I would be pretty pushed to define what my occupation is – researcher, developer, write, journalist, project manager, company director? According to the statistics agency I can only be one. And then how the one, whichever it is, be matched to a university course. Computer programmers increasingly need advanced project management skills. I suspect that one factor driving participation in MOOCs is that people require new skills and knowledge not acquired through their initial degrees for work purposes.
My conclusions – a) Don’t believe everything you read about skills shortages, and b) We need to ensure academic courses provide students with a wide range of skills and knowledge drawn from different disciplines, and c) We need to think in more depth about the link between education and work.
The future of libraries
The NMC Horizon Project, an ongoing research project designed to identify and describe emerging technologies likely to have an impact on teaching, learning, and creative inquiry has released its library edition. Six key trends, six significant challenges, and six important developments in technology are identified across three adoption horizons over the next one to five years, giving library leaders and staff, they say, a valuable guide for strategic technology planning.
The NMC Horizon Report > 2015 Library Edition identifies “Increasing Value of the User Experience” and “Prioritization of Mobile Content and Delivery” as short-term impact trends driving changes in academic and research libraries over the next one to two years. The “Evolving Nature of the Scholarly Record” and “Increasing Focus on Research Data Management” are mid-term impact trends expected to accelerate technology use in the next three to five years; and “Increasing Accessibility of Research Content” and “Rethinking Library Spaces” are long-term impact trends, anticipated to impact libraries for the next five years or more.
