There are not 120,000 "troubled families"

This zombie statistic refuses to die.

The Department for Communities and Local Government has released a report focusing on so-called "troubled families", which presents a compelling case that the worst of these families have problems which need urgent intervention. But it also takes the opportunity to revive one of the department's favourite zombie statistics. A report which is based on formal interviews with 16 families ("although she met and talked with many more") is generalised out to cover 120,000.

This six-figure number is one of the DCLG's favourites. It has been pushing it since at least February, when NIESR's Jonathan Portes first drew attention to the problems with the definition of "troubled". When the Prime Minister quoted the figure, he called these families:

The source of a large proportion of the problems in society. Drug addiction. Alcohol abuse. Crime. A culture of disruption and irresponsibility that cascades through generations.

As Portes pointed out, the actual definition of troubled families focuses far more on them being families with troubles, rather than families causing trouble. The DCLG has an explanatory note on the topic, which defines the families as any holding five or more of the following characteristics:

a) no parent in work
b) poor quality housing,
c) no parent with qualifications,
d) mother with mental health problems
e) one parent with longstanding disability/illness
f) family has low income,
g) Family cannot afford some food/clothing items                                                        

So back in February, the overarching problem with the statistic was how it was used, rather than the number itself. Whether or not there were 120,000 of them, these troubled families are in no way "irresponsible".

But last month, the dishonesty became clearer. Perhaps realising that the rhetoric didn't match up with the definition, the department published a new explanatory note, which claimed that troubled families were:

Characterised by there being no adult in the family working, children not being in school and family members being involved in crime and anti-social behaviour.

That definition does sound much more like one of a family suffering "a culture of disruption and irresponsibility", certainly. But normally, when one changes a definition of something, the number of cases falling under that definition also changes. Not so with the troubled families. The department continued – and continues – to refer to "120,000" of them.

Even worse, when the Prime Minister first referred to the families (using the kinder definition), he did so with an extraordinary level of granularity, saying:

There are an estimated 4,500 of these families in Birmingham, 2,500 in Manchester, and 1,115 here in Sandwell.

Once the definition changed, had the location? Like hell.

As Jonathan Portes concluded his post:

It is difficult to conclude anything except that the Department, and the governnment, have become hung up on the 120,000 number despite the fact that they are well aware that it is now completely discredited, either as a national estimate of the number of "troubled families" or as a sensible guide to local policy.

The release of today's report just confirms that feeling. The figure of 120,000 is mentioned exactly twice in the 30,000 word report (pdf), once in author Louise Casey's foreword and once in the introduction. It is also mentioned twice in the 600 word press release, and twice in each of the Guardian and Mail's reports on the topic. It seems like something which has little to do with the content of the report (an admirable qualititative study of what it's like to live in an incredibly disfunctional household, but one which offers little guidance as to how widespread the problems are) and everything to do with a need to push a continuing narrative.

People like to put numbers on things, so here's one: with the actual information the DCLG has put out, we know of just 16 troubled families, the ones interviewed by Casey. Pick a number any higher than that and you're getting into the same voodoo mathematics the government has been performing for the last six months.

An unmatched font of knowledge

Edinburgh’s global reputation as a knowledge economy is rooted in the performance and international outlook of its four universities.

As sociologist-turned US Senator Daniel Patrick Moynihan recognised when asked how to create a world-class city, a strong academic offering is pivotal to any forward-looking, ambitious city. “Build a university,” he said, “and wait 200 years.” He recognised the long-term return such an investment can deliver; how a renowned academic institution can help attract the world. However, in today’s increasingly globalised higher education sector, world-class universities no longer rely on the world coming to come to them – their outlook is increasingly international.

Boasting four world-class universities, Edinburgh not only attracts and retains students from around the world, but also increasingly exports its own distinctively Scottish brand of academic excellence. In fact, 53.9% of the city’s working age population is educated to degree level.

In the most recent QS World University Rankings, the University of Edinburgh was named as the 21st best university in the world, reflecting its reputation for research and teaching. It’s a fact reflected in the latest UK Research Exercise Framework (REF), conducted in 2014, which judged 96% of its academic departments to be producing world-leading research.

Innovation engine

Measured across the UK, annual Gross Value Added (GVA) by University of Edinburgh start-ups contributes more than £164m to the UK economy. In fact, of 262 companies to emerge from the university since the 1960s, 81% remain active today, employing more than 2,700 staff globally. That performance places the University of Edinburgh ahead of institutions such as MIT in terms of the number of start-ups it generates; an innovation hothouse that underlines why one in four graduates remain in Edinburgh and why blue chip brands such as Amazon, IBM and Microsoft all have R&D facilities in the city.

One such spin out making its mark is PureLiFi, founded by Professor Harald Haas to commercialise his groundbreaking research on data transmission using the visible light spectrum. With data transfer speeds 10,000 times faster than radio waves, LiFi not only enables bandwidths of 1 Gigabit/sec but is also far more secure.

Edinburgh’s universities play a pivotal role in the local economy. Through its core operations, knowledge transfer activities and world-class research the University generated £4.9bn in GVA and 44,500 jobs globally, when accounting for international alumni.

With £1.4bn earmarked for estate development over the next 10 years, the University of Edinburgh remains the city’s largest property developer. Its extensive programme of investment includes the soon-to-open Higgs Centre for Innovation. A partnership with the UK Astronomy Technology Centre, the new centre will open next year and will supply business incubation support for potential big data and space technology applications, enabling start-ups to realise the commercial potential of applied research in subjects such as particle physics.

It’s a story of innovation that is mirrored across Edinburgh’s academic landscape. Each university has carved its own areas of academic excellence and research expertise, such as the University of Edinburgh’s renowned School of Informatics, ranked among the world’s elite institutions for Computer Science. 

The future of energy

Research conducted into the economic impact of Heriot-Watt University demonstrated that it generates £278m in annual GVA for the Scottish economy and directly supports more than 6,000 jobs.

Set in 380-acres of picturesque parkland, Heriot-Watt University incorporates the Edinburgh Research Park, the first science park of its kind in the UK and now home to more than 40 companies.

Consistently ranked in the top 25% of UK universities, Heriot-Watt University enjoys an increasingly international reputation underpinned by a strong track record in research. 82% of the institution’s research is considered world-class (REF) – a fact reflected in a record breaking year for the university, attracting £40.6m in research funding in 2015. With an expanding campus in Dubai and last year’s opening of a £35m campus in Malaysia, Heriot-Watt is now among the UK’s top five universities in terms of international presence and numbers of international students.

"In 2015, Heriot-Watt University was ranked 34th overall in the QS ‘Top 50 under 50’ world rankings." 

Its established strengths in industry-related research will be further boosted with the imminent opening of the £20m Lyell Centre. It will become the Scottish headquarters of the British Geological Survey, and research will focus on global issues such as energy supply, environmental impact and climate change. As well as providing laboratory facilities, the new centre will feature a 50,000 litre climate change research aquarium, the UK Natural Environment Research Council Centre for Doctoral Training (CDT) in Oil and Gas, and the Shell Centre for Exploration Geoscience.

International appeal

An increasingly global outlook, supported by a bold international strategy, is helping to drive Edinburgh Napier University’s growth. The university now has more than 4,500 students studying its overseas programmes, through partnerships with institutions in Hong Kong, Singapore, China, Sri Lanka and India.

Edinburgh Napier has been present in Hong Kong for more than 20 years and its impact grows year-on-year. Already the UK’s largest higher education provider in the territory, more than 1,500 students graduated in 2015 alone.

In terms of world-leading research, Edinburgh Napier continues to make its mark, with the REF judging 54% of its research to be either world-class or internationally excellent in 2014. The assessment singled out particular strengths in Earth Systems and Environmental Sciences, where it was rated the top UK modern university for research impact. Taking into account research, knowledge exchange, as well as student and staff spending, Edinburgh Napier University generates in excess of £201.9m GVA and supports 2,897 jobs in the city economy.

On the south-east side of Edinburgh, Queen Margaret University is Scotland’s first university to have an on-campus Business Gateway, highlighting the emphasis placed on business creation and innovation.

QMU moved up 49 places overall in the 2014 REF, taking it to 80th place in The Times’ rankings for research excellence in the UK. The Framework scored 58% of Queen Margaret’s research as either world-leading or internationally excellent, especially in relation to Speech and Language Sciences, where the University is ranked 2nd in the UK.

In terms of its international appeal, one in five of Queen Margaret’s students now comes from outside the EU, and it is also expanding its overseas programme offer, which already sees courses delivered in Greece, India, Nepal, Saudi Arabia and Singapore.

With 820 years of collective academic excellence to export to the world, Edinburgh enjoys a truly privileged position in the evolving story of academic globalisation and the commercialisation of world-class research and innovation. If he were still around today, Senator Moynihan would no doubt agree – a world-class city indeed.
